1.3
Paging the Loudmouth™ receiver and PA speaker
The Loudmouth™ receiver and PA speaker can be paged with 2-way radios programmed for Quiet Call (CTCSS),
Digital Quiet Call (DCS), 2-Tone Paging, or Selcall paging formats. Each format offers a unique method of paging
™
the Loudmouth receiver and PA speaker.
Refer to the Programming section of this manual for specific instructions on programming your Loudmouth™
receiver and PA speaker to one of these selective signaling formats.
Ritron strongly recommends operation of the Loudmouth™ receiver and PA
speaker with one of the following selective signaling formats enabled.
Paging the Loudmouth™ with Quiet Call (CTCSS) only:
•
To page the loudspeaker a user simply presses the 2-way radio’s PTT and speaks while on the
Loudmouth™ channel.
•
Your 2-way radio must be programmed for a channel dedicated to Loudmouth™ operation. Only those
™
radios programmed with the Loudmouth channel will be able to access the loudspeaker.
•
The 2-way radio’s Loudmouth™ channel and the Loudmouth™ receiver must be programmed for the
same QC code. All Ritron radios offer 50 different field-programmable QC codes from which to choose.
™
Paging the Loudmouth with Digital Quiet Call (DCS) only:
•
To page the loudspeaker a user simply presses the 2-way radio’s PTT and speaks while on the
™
Loudmouth channel.
•
Your 2-way radio must be programmed for a channel dedicated to Loudmouth™ operation. Only those
™
radios programmed with the Loudmouth channel will be able to access the loudspeaker.
•
The 2-way radio’s Loudmouth™ channel and the Loudmouth™ receiver must be programmed for the
same DQC code. All Ritron radios offer 104 different field-programmable DQC codes from which to
choose.
™
Paging the Loudmouth with 2-Tone Paging:
•
To page the Loudmouth™ the 2-way radio must first send the correct 2-Tone Paging code. Once
access to the loudspeaker is accomplished, the user simply presses the 2-way radio’s PTT and speaks
while on the Loudmouth™ channel. After a period of inactivity the Loudmouth™ is automatically reset,
and will then require the correct 2-Tone Paging code to re-gain access.
•
Only 2-way radios programmed to send the correct 2-Tone code on the Loudmouth™ channel can
access the Loudmouth™ wireless PA speaker. However, once access is gained, any 2-way radio that
™
operates on the Loudmouth channel can access the loudspeaker up until the time that the
™
Loudmouth has automatically reset.
•
Can be used in conjunction with QC or DQC for added security. The 2-way radio and the Loudmouth
receiver must be programmed for the same QC or DQC code.
™
Paging the Loudmouth™ with Selcall:
•
To page the Loudmouth™ the 2-way radio must be programmed to send the correct Selcall code every
time the PTT is pressed. The user simply presses the 2-way radio’s PTT and speaks while on the
Loudmouth™ channel.
•
™
Only 2-way radios programmed to send the correct Selcall code on the Loudmouth channel can
™
access the Loudmouth wireless PA speaker.
•
Can be used in conjunction with QC or DQC for added security. The 2-way radio and the Loudmouth
receiver must be programmed for the same QC or DQC code.
Section 1
™
Getting Started
Ritron recommends the use of a dedicated channel frequency for
Loudmouth™ operation.
When operating on unique frequencies dedicated to loudspeaker operation:
•
Your 2-way radios must be programmed for a channel dedicated to loudspeaker operation.
•
Loudspeaker operation is limited to radios programmed with the dedicated Loudmouth™ channel.
•
™
The use of 2-tone or Selcall paging to address the Loudmouth is not required, but can still be used if
additional access security is desired.
•
Without 2-tone or Selcall paging the loudspeaker can be addressed by simply selecting the
Loudmouth™ channel on your 2-way radio and pressing the PTT button to talk.
•
You may need to license additional frequencies (not necessary with LM-V150 programmed for MURS
frequencies, see Table 1 in the Programming section).
When operating on your normal 2-way communication frequencies:
1.4
•
Messages broadcast on the Loudmouth™ are also heard on your 2-way radios.
•
Loudspeaker messages are not possible when the channel is being used for 2-way communications.
•
The use of 2-tone or Selcall paging is required to address the Loudmouth™, otherwise all 2-way
communication is heard on the loud speaker.
•
Any user on your 2-way channel can broadcast over the loudspeaker once it is activated, even if their
2-way radio is not programmed with the correct 2-tone paging code.
•
There is no need to license additional frequencies.
Compatibility with other RITRON model radios
The Loudmouth™ receiver and PA speaker is available in both VHF (LM-V150, 150-165 MHz) and UHF (LM-U450,
450-470 MHz) business band frequencies. Loudmouth™ can be accessed with radios programmed for Quiet Call
(CTCSS), Digital Quiet Call (DCS), 2-Tone Paging, or Selcall paging formats. The following chart can be used to
determine compatibility with existing Ritron radios.

Determine the volume setting
Selecting the correct volume level is critical to the performance of the Loudmouth™ receiver and PA speaker.
Carefully consider the following before deciding on the appropriate volume setting. Refer to the Programming
section of this manual for specific instructions on programming the Volume Level.
Ambient (average) noise level should be considered first when selecting the
volume level.
Increasing the volume level in an effort to cover a wider area will result in:
•
•
•
Undesirably high volume when near the speaker.
Low volume at the outer edges of the coverage area.
A calling radio must be a greater distance from the Loudmouth™ speaker to prevent feedback.
(Feedback is the result of Loudmouth™ speaker audio getting into the calling radio’s microphone.)
When coverage of a large area is required, additional Loudmouth™ speakers may be necessary for
satisfactory performance. See the Installation section of this manual for details on how to install 2 speakers
™
using a single Loudmouth receiver, or multiple receivers and speakers.
1.
Refer to the horizontal shaded bars on the chart below to
determine the sound level that best represents your
location. This should be the ambient, or average sound
level. We will consider the maximum sound level when
we locate the speaker.
2.
Estimate the maximum distance (in feet) that the
loudspeaker must be heard. Locate that distance on the
chart below and follow it up to find the line that is in the
middle of your shaded bar. This line indicates the
optimum Loudmouth™ volume level setting.
EXAMPLE: In the Ritron factory we
need to cover a maximum distance of 50
feet on the factory floor with an ambient
sound level similar to a warehouse. I
find the vertical line at the bottom of the
chart indicating 50 feet, and follow it up
to the shaded bar indicating Warehouse.
The 50% and 75% lines are in the middle
of the Warehouse bar, indicating a
required Loudmouth™ volume setting
between 50 - 75%.

Installation
Proper installation of the Loudmouth™ wireless PA speaker is critical to the
performance and overall satisfaction with your system. With careful consideration
and planning Loudmouth™ will cover up to 100 feet with a single speaker, and can
cover an even wider range with multiple speakers and receivers. This section will
help you plan an installation that is best suited for your environment.
2.1
Selecting the PA speaker location
Speaker location is critical to the performance of the Loudmouth™ receiver and PA speaker. Consider the
following factors before selecting a speaker location.
•
The speaker can be installed either indoors or outdoors.
•
Be sure there is a convenient source of 110VAC power for the RPS-1A power cube and that the radio receiver
box can be located inside, out of the elements. The speaker has a 25 ft. cable, if you need more a standard
RCA phono cable and coupler can be used (ie. Radio Shack Catalog #: 42-2363 and Catalog #: 274-1553).
•
The speaker should not be in an area where the 2-way radio user addressing the speaker will typically be
located. If the radio user is too close to the Loudmouth™ speaker, feedback can occur due to loudspeaker
™
audio getting into the radio microphone. This is a problem related to the 2-way radio, not the Loudmouth
speaker. The use of the Record & Play feature will eliminate this problem.
The speaker must be located at least 10 feet above head level.
At near range the Loudmouth™ speaker is capable of sound levels that can cause
permanent hearing loss and should never be installed in a location where a person
could be directly in front of the speaker.
Install the Loudmouth™ speaker close to the noisiest area you plan to cover.
™
If there is an area with a significantly higher ambient noise level, the Loudmouth
speaker should be located as close as possible to this area. The speaker volume
must be 6 db higher than the ambient noise level in order to be heard.
If the speaker is not close to the highest source of noise, the
volume level will be too loud for the quieter areas.
Section 2
Installation
The Loudmouth™ speaker should be mounted as high as practical and
pointed toward the farthest location you need to cover.
Large obstructions will significantly reduce the coverage area.
Do not place the speaker behind large, tall objects.
Section 2
Installation
2.2
PA Speaker installation
The speaker mount can be installed vertically on a wall,
flat post or support column; or can be mounted
horizontally from a ceiling or rafter beam.

Once the speaker location has been determined the
Speaker Mounting Template may be used to mark the
mounting surface. When using the Speaker Mounting
Template keep in mind that the speaker wire exit is toward
the floor on a wall mounted installation, and toward the
front of the speaker in a ceiling mounted installation.
™
The Loudmouth speaker may be secured to a variety of
surfaces, with each installation presenting unique
requirements for mounting hardware. With this in mind,
mounting screws or hardware are not included with the
Loudmouth™.

Guidelines for mounting the Loudmouth™ speaker:
•
The Loudmouth™ speaker can be safely mounted to concrete, metal or wood surfaces. Other surfaces are
possible provided they can support the weight of the speaker. If mounting to a drywall or concrete surface
the use of expansion anchors is recommended.
•
Secure the speaker tightly to the mounting surface, using all 6 mounting holes if possible. At high audio
output levels the speaker can generate significant vibration and must be rigidly secured. This is particularly
critical with drywall surfaces, which are highly susceptible to vibration damage.
•
Be sure the speaker wire exits cleanly from under the speaker mounting bracket through the wire exit
tunnel provided. Pinching the speaker wires could cause a short that will destroy the Loudmouth™ receiver
audio amplifier.
•
Route the speaker wire closely against a wall or support
beam. Speaker wire hanging in free space is easily
™
snagged and could be pulled from the Loudmouth
receiver or worse yet, pulled from the speaker itself
causing permanent damage.
•
1 inch long, #8 or #10 round-head screws should be
used to mount the speaker. Wood screws, sheet metal
screws, machine screws with nuts, or drywall anchors
and screws will all work well depending on your specific
requirements. Pan-head screws should not be used to
prevent damage to the mounting bracket due to overtightening.

The Loudmouth™ speaker should be mounted
horizontally for the widest coverage
™
When mounted horizontally the Loudmouth
speaker will provide 90° horizontal and 60°
vertical coverage without significant loss of sound
level. Refer to the SPL chart on page 25 for
typical sound levels at full volume.
Installing Concrete Expansion Anchors
1. Drill hole of recommended
diameter, see chart below, into the
base material to a depth equal to,
or slightly deeper than the length
of the expansion shield. Clean out
the hole of all dust and cuttings.
2. Place the Single Expansion
anchor, nut end first, into the hole.
The top end of the anchor should
be flush or slightly below the base
material surface.
3. Place the object to be fastened
over the anchor in the base
material and bolt into place. The
bolt should engage 2/3 of the
threads of the anchor.
2.3
Loudmouth™ radio receiver installation
Installation of the Loudmouth™ receiver is critical to the effective radio coverage of the radio loudspeaker system.
™
Without proper installation the maximum possible distance between the calling radio and the Loudmouth
receiver will be significantly reduced.
Guidelines for installing the Loudmouth™ receiver:
•
The radio receiver box must be located inside, out of the elements.
•
Be sure there is a convenient source of 110VAC power for the RPS-1A power cube.
•
The Loudmouth™ receiver should be installed in a central location and as high up as possible for best radio
coverage.
•
For maximum radio coverage the antenna should be in a vertical orientation and should not be touching or
surrounded by large metal objects. The receiver box can be mounted horizontally as long as the antenna is
in a vertical position.
•
™
Do not install the Loudmouth receiver in a high traffic location with the possibility that the receiver box
would be struck, become unplugged, or the speaker be disconnected.
•
Do not wind, loop or otherwise allow the power cord from the RPS-1A power cube to contact the antenna.
The power cord should be routed away from the antenna.
Radio range can be extended with the use of an external
antenna.
The antenna can be installed at a higher elevation than is possible with the
attached antenna.
The Ritron RAM-1545 VHF/UHF magnet-mount antenna has a 25 ft.
cable to allow optimum antenna location.
Section 2
Installation
2.4
Installing two PA speakers with a single Loudmouth™ receiver
Many locations may require the installation of two speakers with a single Loudmouth™
receiver. Two speakers are used when:
•
Coverage is required over a large area.
•
Large obstructions limit the effective range of a single speaker.
•
A wall separates two coverage areas.
•
The ambient noise level is low and individual speaker volume must be reduced
(i.e. Hospital).
•
The calling radio is in the area where the speakers are located and speaker
volume must be reduced to prevent feedback.
You can connect 2
speakers to a single
Loudmouth™ receiver
using an RCA phono
type Y-connector.
(i.e.Radio Shack
Catalog # 274-881)
In some installations a single Loudmouth™ receiver can be used to drive two
speakers, while others will require a separate receiver for each speaker.
To cover a large area, or an area with large obstructions, place 2 speakers
back-to-back in a central location.
•
The speakers should be mounted as high as possible and pointing away from each other.
•
™
The 2 speakers can be driven by a single Loudmouth receiver.
•
Volume level may be reduced compared to a single speaker, making the system less susceptible to
feedback.
Use 2 Speakers to reduce volume level
Surprisingly, the use of 2 speakers powered by a single
Loudmouth™ receiver can allow you to reduce the volume
level in a quiet environment.
By covering an area with 2 centrally located speakers,
installed back-to-back, the volume level can be cut in half.
Section 2
Installation

2.5
Installing multiple Loudmouth™ receivers and PA speakers
Many locations may require the installation of multiple Loudmouth™ receivers and PA speakers. Multiple receivers
and PA speakers are used when:
•
Paging separate buildings is required.
•
The coverage area is too large for a single receiver and PA speaker.
•
Zone paging is required.
•
Paging is required in more than one location.
Zone paging, or paging in more than one location requires a separate
Loudmouth™ receiver for each area.
•
With zone paging all radios can operate on the same Loudmouth™ radio frequency.
•
Each Loudmouth™ receiver can be programmed for a unique paging code, allowing selective paging to
each zone.
•
The Loudmouth™ receivers can be programmed for an All Call* code that allows paging of all zones at
once, or Group Call* to page more than one zone.
•
Zone paging allows for volume levels that are programmed to the specific needs of that area.
•
™
If zone paging is not necessary, all Loudmouth receivers can be programmed for the same paging
code.
* All Call and Group Call code programming requires the Ritron Loudmouth™ PC Programmer.
Zone 2 – Cafeteria
Zone 1 – Warehouse and loading dock
• Single Loudmouth receiver with 2 speakers.
• Single Loudmouth receiver with 1 speaker.
• One speaker is located inside the warehouse and the
other is located outside for the loading dock.
• The speaker is located inside the cafeteria area.
• Speaker volume is set to 50% for the warehouse
environment.
• Speaker volume is set to 25% for the restaurant
environment.
Zone 3 – Sales office
• Single Loudmouth receiver with 1 speaker.
Example of Zone paging
Section 2
Installation
• The speaker is located inside the Sales office.
• Speaker volume is set to 10% for the office environment.
11
2.6
Vehicular installation
The Loudmouth™ receiver can be powered with an optional Ritron model CCL-M cigarette lighter adapter for use in
mobile applications.
•
Route the CCL-M power cord away from the antenna and speaker wires.
When the speaker is mounted on the roof of a vehicle at head
level the volume level should be reduced to 50% or less to
prevent hearing damage.
2.7
CCL-M
Temporary outdoor installation
The Loudmouth™ receiver can be temporarily installed outdoor with the use of weatherproof enclosures.
The Ritron model LMH-100 is a weatherproof, fiberglass reinforced polyester enclosure
™
designed to house the Loudmouth receiver and antenna. Speaker and power
connections are routed from the bottom of the enclosure through electrical conduit.
The LMH-100 includes:

Program Paging Codes
For paging, it is desirable to program the wireless speaker for 2-Tone or Selcall operation. The user is able to field
program the radio for one of the 9 pre-determined 2-tone pairs specified in Table 4, or for a 3-7 digit Selcall code.
2-Tone codes correspond to field programmable 2-Tone encode (transmit) codes available in other RITRON
portable and base radios. In our example we will program an LM-U450 to operate with 2-Tone Paging Code 94
frequencies of 389.0 and 669.9 Hz.
94
1.
Refer to Table 4 to determine the two-digit code for 2-tone decode on 389.0 and 669.9 Hz
and write it down.
2.
Loosen the (4) captive screws in the front corners of the case. These screws are captive to
the housing; to prevent damaging them, DO NOT remove the screws from the housing.
3.
Separate the case front from the case back, leaving the RPS-1A power supply or backup
battery connected to the radio.
NOTE: The voltage of the batteries must be greater than 6 VDC to program properly.
4.
Press and HOLD the PROGRAM button. A "P" will appear on the program display as you
enter program mode and the radio will beep rapidly.
5.
Release the PROGRAM button after the beeping has stopped. The radio will emit a triple
beep indicating that the radio is in program mode and a hyphen will appear on the program
display.
6.
Scroll to the character “C” by clicking the PROGRAM button until the program display
shows the correct character. Pause—the radio will sound a low tone and show a hyphen
across the center of the display to indicate that it is ready to accept the first digit of the 2Tone or Selcall code.
7.
Enter the 1st digit of the 2-Tone or Selcall code by clicking the PROGRAM button until the
program display shows the desired number. Pause—the radio will sound a low tone and
show a hyphen across the center of the display to indicate that it is ready to accept the
next digit.
8.
nd
Enter the 2 digit of the 2-Tone or Selcall code by clicking the PROGRAM button until the
program display shows the desired number. Pause—the radio sounds a low tone and
show a hyphen across the center of the display to indicate that it is ready to accept the
next digit.
9.
FOR SELCALL CODES ONLY – Enter the 3rd, 4th, 5th, 6th, and 7th digits of the Selcall code
by clicking the PROGRAM button until the program display shows the desired number.
Pause—the radio sounds a low tone and will show a hyphen across the center of the
display to indicate that it is ready to accept the next digit.
10. Press and release the ENTER button to save your programming. A triple beep will sound to
indicate that programming was successful and a hyphen will appear on the program
display. The radio is now ready for another program entry.
NOTE: An error tone will sound if you attempt to save an incorrect code, an "E" will appear
on the display. Check the digits you are attempting to enter, then re-enter.
11. Once you have made your final program entry, press the ENTER button a final time to exit
programming mode. The Program display will be blank and the radio will be ready for use.

channel can talk over the speaker without the need for 2-tone paging.
•
After a 2-tone code has been successfully decoded, the programmable Two-Tone Reset Time sets the
length of time the Loudmouth™ receiver can go without receiving a signal before 2-tone is once again
required for access. Factory default Two-Tone Reset Time is 5 seconds.
•
Can be used in conjunction with QC or DQC for added security. The 2-way radio and the Loudmouth™
receiver must be programmed for the same QC or DQC code.
Record and Play (20 seconds of record time MAXIMUM)
When 2-way radios are used in the same area as the Loudmouth™ speaker, feedback may result that can render
™
the system unusable. For those applications the Loudmouth can be programmed to record the incoming
messages and play them back over the speaker when the PTT button is released on the 2-way radio. Set the
™
portable, base station, or mobile radio to the Loudmouth channel.

Section 4
Operation
22
4.5
Weather Alert
VHF models of the Loudmouth™ can automatically play emergency weather warnings from the National Weather
Service that is broadcast on one of the seven NOAA weather frequencies. The Loudmouth™ will listen for
™
emergency weather broadcasts any time it is not being used. To use this feature the Loudmouth must first be
programmed for your local NOAA weather frequency.
With Weather Alert operation:
•
The Weather Alert feature is only available on the LM-V150 model.
•
Your local NOAA weather frequency must be programmed into the LM-V150 and the Weather Alert feature
must be ON per the instructions in the Programming section of this manual.
•
If a severe weather notification from NOAA weather service occurs while the LM-V150 is in use the Weather
Alert operation will not be activated.
•
When a severe weather notification from NOAA weather service activates Weather Alert operation, the LMV150 will broadcast the NOAA weather alert message non-stop until an end-of-message signal is received
or 2 minutes elapses. The Loudmouth™ cannot be used for regular paging operation as long as the weather
alert message is being played.
•
The maximum Weather Alert Time is set at the factory for 2 minutes, but is PC programmable from 20
seconds to 4 minutes. This time only matters if an end-of-message signal is not received from NOAA
weather service.
The Loudmouth™ receiver and PA speaker is not intended for use as a standalone weather receiver.
4.6
Battery Powered Operation
The Loudmouth™ receiver comes equipped with the BP-LM9 emergency backup battery that can temporarily
power the radio if primary power from the RPS-1A is interrupted. The BP-LM9 is an 800mAH rechargeable battery
pack that is trickle charged by the Loudmouth™ receiver and is not intended to operate the radio for an extended
period of time. For applications where AC power for the RPS-1A is not available, the Loudmouth receiver must be
powered by an external +12 VDC battery. The Loudmouth™ can then be configured for battery powered operation
to maximize battery life.
Battery Operation Enable
Enabling this feature will put the audio amplifier into a standby mode except when a message is played.
•
Depending on usage, this may double the battery life.
•
The caller must wait approximately 1 second before speaking to allow the audio amplifier to turn on.
•
If the Record and Play feature is used the caller does not need to wait before speaking.
Power Save
™
Enable this feature whenever the Loudmouth is battery powered to extend battery life. When enabled the
™
Loudmouth receiver is in a low current “sleep” state the majority of the time, waking up periodically to see if
there is an incoming message to be broadcast.
•
Depending on usage, this may double the battery life.
•
The length of time the Loudmouth™ can “sleep” before it checks for a message is PC programmable from .5
to 8 seconds.
•
With Power Save enabled the caller must wait approximately 2 second before speaker to allow the radio to
wake up.
Low Battery Alert Tone
Enable this feature whenever the Loudmouth™ is battery powered and a short tone will be heard at the end of
each broadcast to indicate that the batteries need replacement or recharging.
Section 4
Operation
23
4.7
Loudmouth™ Options
Certain Loudmouth™ options affect operation as follows:
Pre-Announce Tone
With this feature enabled the Loudmouth™ will sound a short tone prior to each broadcast to notify listeners that
a page is forthcoming.
One Speaker / Two Speakers
™
Set the Loudmouth for one or two speaker operation to set the correct audio output level from the audio
amplifier.
4.8
How to Minimize Feedback
Feedback is the result of the Loudmouth™ speaker audio getting back into the microphone of the radio being used
™
™
to access the Loudmouth . This is a problem with the calling radio, not the Loudmouth receiver. Although the
™
Loudmouth is not intended to be used in the same area as the calling radio, steps can be taken to minimize the
feedback effect.
™
Reduce Loudmouth speaker volume
Do not set the Loudmouth™ volume any high than is necessary to cover the intended area.
Use multiple speakers
The use of multiple speakers means you don’t have to cover as large an area with each speaker, consequently,
speaker volume can be reduced.
Maintain distance between the calling radio and the Loudmouth™ speaker
In general, the calling radio should be at least 50 feet away from the speaker when the Loudmouth™ is set for
50% volume. The necessary distance increases if the volume is turned up and decreases if the volume is
turned down.
Make sure the radio microphone is turned away from the speaker
You do not want the speaker pointing directly into the microphone. Using your hand to shield the microphone
can also reduce feedback.
Use a noise canceling microphone
Equip your calling radio with an optional noise-canceling microphone.
Record and Play feature eliminates feedback
The Record and Play feature completely eliminates feedback by recording your
message and playing it back immediately after you have finished sending it to the
Loudmouth™ receiver. See page 18 to enable the Record and Play operation.
The calling radio is not transmitting while the message is broadcast, so speaker
audio cannot get into the calling radio microphone.

Getting Started
The LPA-Series receiver is designed for interface to existing wired Public Address
systems to allow PA announcements using VHF or UHF business band, FRS, or
MURS radios.
Major Benefit:
The LPA receiver allows all the wired speakers in a PA/Intercom system immediately accessible via a
2-way radio/base station/ etc. The LPA receiver can be connected to an existing wired system. An
LM and LPA receiver system can be used side-by-side on the same frequency.
What is The Difference b/w The LM-V150/U450 Receiver and The LPA-V150/U450 Receiver?
•
The LM Receiver (#LM-V150/U450) has a built-in audio amplifier. The built-in audio amplifier allows the LM receiver
by itself to drive up to 2 Ritron PA horn speakers. The LM receiver and included PA Horn speaker is what we call a
stand-alone wireless PA system.
•
LPA Receiver (#LPA-V150/U450) does not have a built-in PA amplifier. The LPA receiver is designed to be
connected to an existing PA/intercom system with its own PA amplifier and wired speakers.
•
The LPA receiver does not include a back-up battery since it is merely a component of a larger system usually
powered by AC and its own battery back-up system.
Features/Benefits:
•
Available in VHF (150-162 MHz) and UHF (450-470MHz) frequency bands. Provides compatibility with business
band 2-way radios, License-FREE VHF business band radios (MURS), Family Radio Service and GMRS radios.
•
Provides interconnection to the Public Address amplifier through a high impedance, unbalanced AUX input OR a
600Ω, balanced MIC input. Allows personnel to remain mobile while providing access via 2-way radio access to
existing PA speakers located throughout the facility.
•
If the AUX input of the PA/Intercom amplifier is already used (ie: stereo tuner for background music) the LPASeries is installed in-between the audio source (stereo tuner) and the PA/Intercom amplifier. When the LPA-Series
receives a message the audio source is interrupted and the received message is sent to the PA/Intercom amplifier
instead.
•
“Record and Play” allows use of radios in close proximity to PA speakers without feedback. The LPA-Series
records/buffers received messages up to 30 seconds in length, then plays them over the PA immediately after
releasing the PTT button on the radio.
•
Easy “Plug and Play” installation.
•
Programmable volume control adjusts
audio output level 5-99%. Allows custom
adjustment for most applications.
•
Selective signaling includes QC, DQC,
Selcall, 2-Tone to provide an added layer
of access control to the PA system.
•
Pre-announce tone (similar to existing PA
systems) with programmable on/off and
volume level.
•
NOAA Weather Alert (VHF only).
•
Field or PC programmable to frequencies
within the respective band (i.e. 150-165
MHz, 450-470 MHz).
•
The LPA-Series is for interface only to an
existing PA system, it cannot drive a
loudspeaker by itself.
•
The LPA-Series is for indoor use ONLY.

1.2
Paging the LPA-Series receiver
The LPA-Series receiver can be paged with 2-way radios programmed for Quiet Call (CTCSS), Digital Quiet Call
(DCS), 2-Tone Paging, or Selcall paging formats. Each format offers a unique method of paging the LPA receiver.
Refer to the Programming section of this manual for specific instructions on programming your LPA receiver to one
of these selective signaling formats.
Ritron strongly recommends operation of the LPA-Series receiver with one
of the following selective signaling formats enabled.
Paging the LPA-Series receiver with Quiet Call (CTCSS) only:
•
To page the LPA receiver a user simply presses the 2-way radio’s PTT and speaks while on the LPA
channel.
•
Your 2-way radio must be programmed for a channel dedicated to LPA receiver operation. Only those
radios programmed with the LPA channel will be able to access the loudspeaker.
•
The 2-way radio’s LPA channel and the LPA receiver must be programmed for the same QC code. All
Ritron radios offer 50 different field-programmable QC codes from which to choose.
Paging the LPA-Series receiver with Digital Quiet Call (DCS) only:
•
To page the LPA receiver a user simply presses the 2-way radio’s PTT and speaks while on the LPA
channel.
•
Your 2-way radio must be programmed for a channel dedicated to LPA receiver operation. Only those
radios programmed with the LPA channel will be able to access the loudspeaker.
•
The 2-way radio’s LPA channel and the LPA receiver must be programmed for the same DQC code.
All Ritron radios offer 104 different field-programmable DQC codes from which to choose.
Paging the LPA-Series receiver with 2-Tone Paging:
•
To page the LPA receiver the 2-way radio must first send the correct 2-Tone Paging code. Once
access to the LPA receiver is accomplished, the user simply presses the 2-way radio’s PTT and speaks
while on the LPA channel. After a period of inactivity the LPA receiver is automatically reset, and will
then require the correct 2-Tone Paging code to re-gain access.
•
Only 2-way radios programmed to send the correct 2-Tone code on the LPA channel can access the
LPA receiver. However, once access is gained, any 2-way radio that operates on the LPA channel can
access the LPA receiver up until the time that the LPA receiver has automatically reset.
•
Can be used in conjunction with QC or DQC for added security. The 2-way radio and the LPA receiver
must be programmed for the same QC or DQC code.
Paging the LPA-Series receiver with Selcall:
•
To page the LPA receiver the 2-way radio must be programmed to send the correct Selcall code every
time the PTT is pressed. The user simply presses the 2-way radio’s PTT and speaks while on the LPA
channel.
•
Only 2-way radios programmed to send the correct Selcall code on the LPA channel can access the
LPA receiver.
•
Can be used in conjunction with QC or DQC for added security. The 2-way radio and the LPA receiver
must be programmed for the same QC or DQC code.
Section 1
Getting Started
Ritron recommends the use of a dedicated channel frequency for LPA
operation.
When operating on unique frequencies dedicated to LPA operation:
•
Your 2-way radios must be programmed for a channel dedicated to LPA operation.
•
LPA-Series receiver operation is limited to radios programmed with the dedicated LPA channel.
•
The use of 2-tone or Selcall paging to address the LPA receiver is not required, but can still be used if
additional access security is desired.
•
Without 2-tone or Selcall paging the LPA receiver can be addressed by simply selecting the LPA
channel on your 2-way radio and pressing the PTT button to talk.
•
You may need to license additional frequencies (not necessary with LPA-V150 programmed for MURS
frequencies, see Table 1 in the Programming section).
When operating on your normal 2-way communication frequencies:
1.3
•
Messages received by the LPA-Series receiver and broadcast on the wired PA system are also heard
on your 2-way radios.
•
LPA operation is not possible when the channel is being used for 2-way communications.
•
The use of 2-tone or Selcall paging is required to address the LPA receiver, otherwise all 2-way
communication is heard on the wired PA system.
•
Any user on your 2-way channel can broadcast over the wired PA system once the LPA receiver is
activated, even if their 2-way radio is not programmed with the correct 2-tone paging code.
•
There is no need to license additional frequencies.
Compatibility with other RITRON model radios
The LPA-Series receiver is available in both VHF (LPA-V150, 150-165 MHz) and UHF (LPA-U450, 450-470 MHz)
business band frequencies. LPA receivers can be accessed with radios programmed for Quiet Call (CTCSS),
Digital Quiet Call (DCS), 2-Tone Paging, or Selcall paging formats. The following chart can be used to determine
compatibility with existing Ritron radios.

Installation
Proper installation of the LPA-Series receiver is critical to the performance and
overall satisfaction with your system. With careful consideration and planning the
LPA-Series can receive a radio signal from up to a mile away and broadcast it over
your wired PA system. This section will help you plan an installation that is best
suited for your environment.
2.1
Radio coverage site survey
Ritron recommends that you do a “radio coverage site survey” before
permanently installing the LPA-Series receiver.
This will require 2 people and 2 charged portable radios.
Every building is different, and therefore, no “single” rule applies when it comes to where to install the LPA receiver
and antenna for optimal coverage. Ideally, you would like to install the LPA-Series receiver in close proximity to
the wired PA amplifier for easy installation. Begin your site survey by locating person #1 at the wired PA amplifier
to see if a simple installation is possible. If that is not possible, an alterative site must be found where:
1.
2.
AC power is available for the LPA receiver.
A shielded, twisted pair cable can be routed from the LPA receiver to the PA amplifier.
In general, the antenna of the LPA receiver is the “pivot” point for all communication. We’re trying to optimize the
location of the antenna in order to reduce the obstructions and distance the radio signal must travel in order to get
from any point in the desired coverage area to the antenna connected to the LPA receiver. By attempting to install
the ANTENNA for the LPA receiver “in the center” of the desired coverage area, we reduce the distance the radio
signal must travel by ½. If you’re attempting to cover a high rise building (e.g. 15 floors), go to a location half way
up (e.g. 7th floor), and in the center of the building.
Radio range can be extended with the use of an external
antenna.
The antenna can be installed at a higher elevation than is possible with the
attached antenna.
The Ritron RAM-1545 VHF/UHF magnet-mount antenna has a 25 ft.
cable to allow optimum antenna location.
Preparing for the radio coverage site survey:
1.
Charge the radio batteries for at least 12 hours.
2.
When charged, make sure both radios are set to the same channel.
Note:
Section 2
If you do not intend to route LPA communications through a repeater, the portable radios should be set to
a channel programmed for direct radio-to-radio communication, NOT through the repeater.
Installation
Conducting the radio coverage site survey:
1.
Person #1 will take one portable radio and go to the location you would “most likely” install the antenna for the
LPA receiver (see FIG-2). This person will “simulate” the type of coverage you can expect, IF, the antenna for
the LPA receiver was installed in this location. If necessary, position this person on a ladder to more
accurately mimic the height you intend to mount the antenna.
BE ADVISED – you may have to try several heights and/or locations before settling on the best location.
2.
While person #1 remains stationary, person #2 will take the second radio and “walk the site”. While “walking
the site” person #2 must attempt to maintain radio contact periodically with person #1. This survey process will
reveal whether or not radio coverage is acceptable IF you install the antenna at the person #1 location.
Generally speaking, coverage will be slightly better when the LPA receiver and antenna are permanently
installed.
3.
If coverage is inadequate, Person #1 will need to relocate to a new location and repeat the process until range
and coverage are optimized.
Hints: Typically, the higher the antenna the better but, NOT always. Every site is different. Thick, reinforced
concrete, steel walls and vertical fire panels in ceilings can work to block the penetration of radio signals
creating dead spots. You may want to gradually lower the height of the antenna and/or its location and repeat
your site survey to see if coverage improves. It is best to change one variable at a time e.g. antenna height,
location and then repeat the process.
4.
For sites where coverage is desired in multiple buildings, such as an office complex, an external mounted
antenna may be required. Before considering an external installation of the antenna, a site survey should be
attempted with person #1 positioned inside a centrally located building at the highest possible elevation (see
FIG-3). Person #2 will “walk the site”, communicating with person #1 from inside all buildings and at all
outside areas where radio coverage is desired.
Person #1 remains at the
location you will install the
LPA receiver, possibly on
a ladder to simulate the
location of an external
mounted antenna.

Installation
Installing a Magnetic Mount Antenna for the LPA-Series Receiver
A magnetic mount antenna should be installed in a location, which is at, or as close as possible to the best location as
determined by the site survey. The antenna’s magnetic base must be attached to a piece of metal (i.e. steel or iron).
The antenna comes with 12 feet of attached co-axial cable* so you can remotely locate the antenna up to 12 feet away
from the LPA-Series receiver. The antenna cable MUST run directly away from the LPA receiver.
* Do NOT attempt to cut, shorten or splice this cable in any way.
For best performance the magnetic mount antenna must be:
•
Mounted on a metal surface e.g. steel or iron. This metal mounting surface MUST be at least 2 feet square with
the antenna positioned in the center. The antenna’s internal magnet will secure it to the surface. Do NOT place
adhesives between the bottom of the antenna mounting surface and the metal mounting surface itself.
•
Orient the antenna so that the element itself is vertical. The antenna can be mounted upside down with no affect
on performance. Just make sure the antenna element is vertical.
•
Mounted away from other metal objects, walls, and structures. Avoid surrounding the antenna or “shielding” it by
locating it too closely to metal walls, inside an elevator shaft, in recessed girders, firewalls or ceilings.
2.2
LPA-Series radio receiver installation
Installation of the LPA receiver is critical to the effective radio coverage of the radio PA
system. Without proper installation the maximum possible distance between the calling
radio and the LPA receiver will be significantly reduced.
Guidelines for installing the LPA-Series receiver:
•
The radio receiver box must be located inside, out of the elements.
•
For best radio coverage the LPA receiver should be installed in a central
location and as high up as possible.
•
For maximum radio coverage the antenna should be in a vertical orientation
and should not be touching or surrounded by large metal objects. The receiver
box can be mounted horizontally as long as the antenna is in a vertical
position.
•
Do not install the LPA receiver in a high traffic location with the possibility that
the receiver box would be struck, become unplugged, or disconnected from the
PA amplifier.
•
If connection to the PA amplifier is via it’s AUX IN, the
LPA receiver must be within 6 ft. of the PA amplifier.
•
Do not wind, loop or otherwise allow the power cord from the RPS-1A
power cube to contact the antenna. The power cord should be routed
away from the antenna.
•
Be sure there is a convenient source of 110VAC power for the RPS1A power cube.

Section 2
Installation
2.3
LPA-Series AUX IN installation
The LPA-Series receiver can connect to the AUX INPUT of a public address
amplifier if the LPA receiver is installed in close proximity to the PA amplifier.
•
The RCA phono cables required for interconnection should be no longer than 6 feet. Installations requiring
LPA receiver location greater than 6 feet from the PA amplifier must use the 600Ω balanced output.
•
If the AUX INPUT of the PA amplifier is already used, the LPA receiver is connected between the AUX audio
source (stereo tuner, cd player, tape player, etc.) and the PA amplifier as shown.
•
Audio from the AUX audio source will be routed to the PA amplifier as normal when the LPA receiver is not
in use. When an LPA radio message is received, the LPA receiver will disconnect the AUX audio source
and replace it with the radio transmission. Once the radio message is complete the AUX audio source is reconnected to the PA amplifier.
•
When using the PA amplifier AUX INPUT it is important to remember that received messages from the LPA
receiver will be treated exactly the same way any other audio device connected to the AUX INPUT. On
many PA amplifiers the AUX INPUT audio is automatically muted whenever audio is present on the MIC
INPUT. Check the owner’s manual for the PA amplifier to determine AUX INPUT operation and the effect it
will have on LPA operation.

LPA-Series 600Ω BALANCED installation
The LPA-Series receiver can be connected to the 600Ω balanced MIC INPUT of
a public address amplifier when the LPA receiver is not located close to the PA
amplifier.
•
When an LPA radio message is received, the LPA receiver will send the audio to the 600 Ω microphone input
of the PA amplifier.
•
A typical balanced cable contains two identical wires, which are twisted together and then wrapped with a third
conductor (foil or braid) that acts as a shield. The wires are twisted together, to reduce interference from
electromagnetic induction. Twisting makes the loop area between the conductors as small as possible, and
ensures that a magnetic field that passes equally through adjacent loops will induce equal but opposite
currents, which cancel out. The separate shield of a balanced audio connection also yields a noise rejection
advantage over an unbalanced two-conductor arrangement (such as AUX IN) where the shield must also act
as the signal return wire. Any noise currents induced into a balanced audio shield will not therefore be directly
modulated onto the signal, whereas in a two-conductor system they will be. This also prevents ground loop
problems, by separating the shield/chassis from signal ground.
NOTE: To minimize noise it is often necessary to connect the ground shield at only one end of the cable.

If a 5 digit is displayed, the LPA receiver has been programmed for DQC and the last three digits indicate the
DQC code; see Table 3 on page 16. In this example an LPA-U450 was programmed to operate on the
“Brown Dot” frequency of 464.500 MHz (Frequency code “04”) with a DQC code of “723”.

If more than 5 digits are displayed, the radio has been programmed for Selective Signaling Decode. The
frequency and tone codes will be displayed, followed by a “C”, then the radio will display either the 2-digit, 2Tone paging code (see Table 4 on 16) or the 3-7 digit Selcall code. In this example an LPA-U450 was
programmed to operate on the “Brown Dot” frequency of 464.500 MHz (Frequency code “04”) with 100.0 Hz
tone (Tone code “12”) and 2-tone paging decode frequencies of 330.5 Hz and 569.1 Hz (2-Tone code “91”)

Program Paging Codes
For paging, it is desirable to program the LPA-Series receiver for 2-Tone or Selcall operation. The user is able to
field program the radio for one of the 9 pre-determined 2-tone pairs specified in Table 4, or for a 3-7 digit Selcall
code. 2-Tone codes correspond to field programmable 2-Tone encode (transmit) codes available in other RITRON
portable and base radios. In our example we will program an LM-U450 to operate with 2-Tone Paging Code 94
frequencies of 389.0 and 669.9 Hz.
94

Program LPA-Series Volume
The LPA-Series receiver can be field programmed for any volume level between 05-99% by entering the volume
level as a 2-digit code. The LPA receiver is set from the factory with a 50% volume setting. If your PA amplifier
has independant volume control you should not have to adjust the LPA receiver volume. If there is no volume
control, or if the PA amplifier volume control is pre-set for background music, you can adjust the input level to the
PA amplifier by adjusting the LPA receiver volume. Field programming Volume Level sets both the voice and the
pre-announce tone volume levels. The PC programmer is required for independent programming of the voice and
the pre-announce tone volume.
In our example we will program an LPA-U450 for 25% Speaker Volume Level.

Operation
Once installed, operating the LPA-Series radio receiver requires no human contact.
Portable, base station or mobile 2-way radios can deliver voice messages directly
to a PA system with a simple press of the PTT button for either live or recorded
playback. This section describes the subtle differences in operation for various
LPA-Series options and installations.
4.1
Basic Operation
Basic operation is defined as a LPA-Series receiver programmed on a dedicated radio frequency with a QC or
DQC code. The receiver is also programmed for 50% volume and a pre-announce tone.

4.2
Move to an area that is away from any PA system speaker to prevent feedback.
Be sure the microphone on the calling radio is pointed away from any PA system speaker.
Set the portable, base station, or mobile radio to the LPA channel.
Monitor the channel before transmitting to be sure there are no other radio users on the LPA frequency.
Press and hold the PTT button and pause for about 1 second, allowing the pre-announce tone to be heard.
Speak into the radio microphone to broadcast your message over the PA system speakers. If other radios
are operating on the LPA channel they will also hear your message.
Release the PTT button when your message is complete.
Return the portable, base station, or mobile radio to the normal operating channel.
Selcall Paging
To access the LPA-Series receiver the 2-way radio must be programmed to send the correct Selcall code every
time the PTT is pressed. The user simply presses the 2-way radio’s PTT and speaks while on the LPA channel.
Only 2-way radios programmed to send the correct Selcall code on the LPA channel can access the PA system.

2-Tone Paging
To access the LPA-Series receiver the 2-way radio must first send the correct 2-Tone Paging code. Once access
to the PA system is accomplished, the user simply presses the 2-way radio’s PTT and speaks while on the LPA
channel. After a period of inactivity the LPA receiver will automatically reset, and will then require the correct 2Tone Paging code to re-gain access.

Move to an area that is away from any PA system speaker to prevent feedback.
Be sure the microphone on the calling radio is pointed away from any PA system speaker.
Set the portable, base station, or mobile radio to the LPA channel.
Monitor the channel before transmitting to be sure there are no other radio users on the LPA frequency.
Send the correct 2-Tone Paging code. Refer to your 2-way radio’s user manual to determine how you send
2-tone paging codes.
6. Wait until the entire 2-tone code has been sent.
7. Press and hold the PTT button and pause for about 1 second, allowing the pre-announce tone to be heard.
8. Speak into the radio microphone to broadcast your message over the PA system speakers. If other radios
are operating on the LPA channel they will also hear your message.
9. Release the PTT button when your message is complete.
10. If the radio PTT is pressed again before the LPA receiver has reset, the message will be heard on the
speaker without the need for a 2-tone Paging code.
11. Return the portable, base station, or mobile radio to the normal operating channel.
With 2-Tone Paging operation:
4.4
•
Once LPA receiver has decoded the correct 2-tone code any radio on the LPA channel can talk over
the speaker without the need for 2-tone paging.
•
After a 2-tone code has been successfully decoded, the programmable Two-Tone Reset Time sets the
length of time the LPA receiver can go without receiving a signal before 2-tone is once again required
for access. Factory default Two-Tone Reset Time is 5 seconds.
•
Can be used in conjunction with QC or DQC for added security. The 2-way radio and the LPA receiver
must be programmed for the same QC or DQC code.
Record and Play (20 seconds of record time MAXIMUM)
When 2-way radios are used in the same area as the PA system speakers, feedback may result that can render
the system unusable. For those applications the LPA-Series receiver can be programmed to record the incoming
messages and play them back over the PA system speakers when the PTT button is released on the 2-way radio.
Set the portable, base station, or mobile radio to the LPA channel.
1.
2.
3.

6.
Monitor the channel before transmitting to be sure there are no other radio users on the LPA frequency.
Press and hold the PTT button on your 2-way radio.
Speak into the radio microphone to record your message into the LPA-Series receiver. If other radios are
operating on the LPA channel they will hear your message as you record it.
Release the PTT button when your message is complete.
The pre-announce tone will be heard and the PA system speakers will begin playing your recorded
message.
When finished, return the portable, base station, or mobile radio to the normal operating channel.
With Record and Play operation:
•
Recorded messages are limited to a maximum of 20 seconds.
•
Any of the selective signaling options can be used in conjunction with Record and Play.
•
The LPA receiver cannot record (buffer) an incoming message while in the process of playing a
message on the speaker.

Weather Alert
VHF model LPA-V150 can automatically play emergency weather warnings from the National Weather Service
that is broadcast on one of the seven NOAA weather frequencies. The LPA-V150 will listen for emergency
weather broadcasts any time it is not being used. To use this feature the LPA-V150 must first be programmed for
your local NOAA weather frequency.
With Weather Alert operation:
•
The Weather Alert feature is only available on the LPA-V150 model.
•
Your local NOAA weather frequency must be programmed into the LPA-V150 and the Weather Alert feature
must be ON per the instructions in the Programming section of this manual.
•
If a severe weather notification from NOAA weather service occurs while the LPA-V150 is in use the
Weather Alert operation will not be activated.
•
When a severe weather notification from NOAA weather service activates Weather Alert operation, the LPAV150 will broadcast the NOAA weather alert message non-stop until an end-of-message signal is received
or 2 minutes elapses. The LPA-150 cannot be used for regular paging operation as long as the weather
alert message is being played.
•
The maximum Weather Alert Time is set at the factory for 2 minutes, but is PC programmable from 20
seconds to 4 minutes. This time only matters if an end-of-message signal is not received from NOAA
weather service.
The LPA-Series receiver is not intended for use as a stand-alone weather
receiver.
4.6
Battery Powered Operation
For applications where AC power for the RPS-1A is not available, the LPA-Series receiver can be powered by an
external +12 VDC battery. The LPA receiver can then be configured for battery powered operation to maximize
battery life.
Power Save
Enable this feature whenever the LPA receiver is battery powered to extend battery life. When enabled the LPA
receiver is in a low current “sleep” state the majority of the time, waking up periodically to see if there is an
incoming message to be broadcast.
•
Depending on usage, this may double the battery life.
•
The length of time the LPA receiver can “sleep” before it checks for a message is PC programmable from .5
to 8 seconds.
•
With Power Save enabled the caller must wait approximately 2 second before speaker to allow the radio to
wake up.
Low Battery Alert Tone
Enable this feature whenever the LPA receiver is battery powered and a short tone will be heard at the end of
each broadcast to indicate that the batteries need replacement or recharging.
Section 4
Operation

4.7
LPA-Series Options
Certain LPA-Series options affect operation as follows:
Pre-Announce Tone
With this feature enabled the LPA receiver will sound a short tone prior to each broadcast to notify listeners that
a page is forthcoming.
4.8
How to Minimize Feedback
Feedback is the result of the PA system speaker audio getting back into the microphone of the radio being used to
access the LPA receiver. This is a problem with the calling radio, not the LPA receiver. Although the LPA receiver
is not intended to be used in the same area as the calling radio, steps can be taken to minimize the feedback
effect.
Reduce LPA receiver speaker volume
Do not set the LPA receiver volume any high than is necessary to clearly hear the PA messages.
Maintain distance between the calling radio and the PA system speakers
In general, the calling radio should be at least 50 feet away from the speaker when the LPA receiver is set for
50% volume. The necessary distance increases if the volume is turned up and decreases if the volume is
turned down.
Make sure the radio microphone is turned away from the speaker
You do not want the speaker pointing directly into the microphone. Using your hand to shield the microphone
can also reduce feedback.
Use a noise canceling microphone
Equip your calling radio with an optional noise-canceling microphone.
Record and Play feature eliminates feedback
The Record and Play feature completely eliminates feedback by recording your
message and playing it back immediately after you have finished sending it to the
LPA receiver. See page 18 to enable the Record and Play operation.
The calling radio is not transmitting while the message is broadcast, so speaker
audio cannot get into the calling radio microphone.
