II. Introduction
The LCT-XX Sensor Transmitter is a sophisticated processor and transmitter housed in
a compact rugged case which facilitates storage, transportation, and concealment. This
unit is ideal for long term deployment from 3 months to one year or longer depending on
configuration. Constructed of injection-molded plastic, the watertight and corrosionproof case may either be deployed above ground or buried for security and stealth.
Only the antenna needs to be above ground for proper operation.
A single LCT-XX unit receives, processes, and transmits information generated by
contact closure/open, seismic (SPS-21), passive infrared (PIR), or dual-axis
magnetometer (MS-10) probes either individually or in various combinations of
deployment, giving the system maximum flexibility. A classify/detect switch combined
with PORT SELECT switches control how the inputs are processed. Four standard
models are available with the following designations and inputs:
LCT-DS
1 Directional + 1 Seismic + 1 Pair N.O. Contacts
LCT-DD
2 Directional
LCT-SS
2 Seismic + 1 Pair N.O. Contacts
LCT-CC
3 Pairs N.O. Contacts + 3 Pairs N.C. Contacts
The LCT-XX was optimized to operate on two 6 VDC lantern batteries and can transmit
over 90,000 alarms before battery replacement is required. Other power supply options
are available and include rechargeable batteries as well as an external power input for
sources such as an external battery, solar-panel, or other 12 VDC supply. Proper
selection of these options depends on environmental conditions and the length of time
the unit is to be deployed. For further information, contact Monitron, Inc.
Alarm Format
When an intrusion is detected and classified, an alarm is encoded using the following
format:
XXXX-P, where: XXXX = unit’s address, P = alarm Port number generated by
the processor. When the LCT-XX generates a self test alarm, or a test alarm is
manually sent, P is the unit’s programmed port number.
The letter “B” is added to the end of the alarm message when the batteries need
to be replaced.
NOTE: Although Monitron equipment is 100% backwards compatible with earlier
Sparton sensor products still in use, Sparton repeaters and monitors are limited to
addresses in the range of 0000 through 1999.

III.Connections & Controls
Input connectors and the standard BNC
jack for the antenna are located on the
lid of the LCT-XX. Note that input J1 is
closer to the handle and J2 is closer to
the hinge.
Control functions for channel select, alarm repeat, selftest time, and address are set using decimal format rotary
switches, which are clearly labeled and easily read.
Each sensor input has user selectable individual
sensitivity gain setting and alarm number (Port). A slide
switch controls operation in either classify or detect mode.

IV.
Antenna Preparation
Using the Allen wrench included with the antenna, loosen the set screw in the side of
the BNC connector and remove the whip. Refer to the Rod Cutting Chart included with
the antenna and cut the whip to the length appropriate for the frequency the LCT-XX will
be transmitting on. Insert the whip into the connector and tighten the set screw.
V. Battery Installation
The LCT-XX has been impedance matched for use with two Duracell ProCell 6 volt
lantern batteries (PC915). The use of inferior batteries may significantly shorten
operational time.
Connect the red wire of the battery wire harness to the positive terminal of the first
battery (Figure 1) and the black wire to the negative terminal of the second battery.
Connect the black jumper wire to the remaining two terminals. Tape the batteries
together (Figure 2) to prevent unnecessary movement.
Figure 1
Figure 2
Insert the batteries on their side into the cutout section of foam in the bottom of the LCTXX case. Orient the batteries so that the screw terminals are in the center of the case.
Install the antenna BEFORE plugging the battery into the into ET board socket, as
shown in Figure 3. NOTE: It is normal for the LCT-XX to transmit one to three “false”
alarms right after the batteries are connected. It also transmits the first self-test within
one minute of powering up.

VI.
Encoder/Transmitter Settings
All Encoder/Transmitter functions are set via the decimal-format rotary switches. To
avoid damage to the switch, adjustments should ONLY be made with a standard, flatblade 2.5 mm screwdriver. The triangle points to the current switch position. There are
also detents at each position providing a tactile indication that the switch is properly set.
Failure to have the switch settled in the detent will lead to erratic behavior. Switch
functions are as follows:
Channel:
Valid settings are 1-8. Channel settings implement the channel
frequencies that have been pre-programmed into the transmitter.
Setting Channel select to 0 or 9 does not cause a malfunction; 9 is
equivalent to channel 1, and 0 is equivalent to channel 8.
Repeat:
Valid settings are 0 through 3.
0 – No repeat. One message sent for every alarm or self test.
1 – 1 repeat. 2 messages total per alarm.
2 – 2 repeats. 3 messages total per alarm.
3 – 3 repeats. 4 messages total per alarm.
Settings 4-9 are reserved. Setting Repeat to these positions will not cause the unit to
malfunction, but should be avoided as they may be used to implement future diagnostic
modes.
Self-Test:
Settings are 0 through 9.
0 – No self-test is sent.
1 – Self-test sent once per minute.
2 – Self-test sent once every five minutes.
3 – Self-test sent once every 65 minutes.
4 – Self-test sent once every 360 minutes (6 hours).
5 - Self-test sent once every 1500 minutes (25 hours). DEFAULT
6 – Self-test sent once every 25 hours w/transmit inhibit 5 seconds
7 – Self-test sent once every 25 hours w/transmit inhibit 10 seconds
8 – Self-test sent once every 25 hours w/transmit inhibit 15 seconds
9 - Self-test sent once every 25 hours w/transmit inhibit 25 seconds
o The processor reads the self-test switch once a minute to check for a change in
setting. When a change is detected the LCT-XX transmits a Port 4 alarm and the
new self test interval begins.
o Self-test transmissions begin within 60 seconds after the operator changes the
Self-Test switch.
o After an alarm is sent, the Transmit Inhibit, selectable by positions 6-9, prevents
the LCT-XX from sending any alarms for the specified time.
Address:
Set the desired four-digit unit address, reading from top to bottom.
The address can be any number between 0000 and 9999.

VII. Setting Gain Level
Gain Switch Locations
Gain switches adjust the sensitivity of the sensor. One (1) is the lowest gain level and
eight (8) is the highest level. To select a gain, press the switch in towards the board. It
is important to use ONLY the minimum gain needed for the area under
surveillance to reduce the possibility of false alarms. For directional inputs, set
both gain switches for a particular input to the same value. The picture above is for an
LCT-DS. For LCT-DD transmitters, the Seismic Gain switches on the right are replaced
by two sets of Directional Gain switches like those on the left. For LCT-SS transmitters,
the two sets of Directional Gain switches on the left are replaced by a single bank of
Seismic Gain switches.
GAIN WARNINGS:
•
For Directional Gains, both the Right and Left channels must be set.
•
Gain for an unused input must be set to one for the LCT-XX to function
properly.
•
There is no “zero” gain. If a gain is not selected, background noise is
amplified by a factor of 700,000 rendering the LCT-XX inoperative until the
gain is correctly set.
LCT-XX L5 USER’S MANUAL

VIII. Selecting Classify or Detect Mode
In Classify Mode, the LCT-XX generates alarm codes based on the TYPE of signal the
probe sees, regardless of the input source. Although there are special situations where
two probes provide the most effective intrusion detection, Classify Mode is utilized
primarily with a single probe to:
•
•
Discriminate between pedestrian and vehicular seismic signals
Determine direction of travel in front of infrared and magnetic probes
In Detect Mode, the LCT-XX generates alarm codes based on which input SOURCE (J1
or J2) is stimulated, but does not distinguish the type (vehicle/pedestrian or direction of
travel) of the signal. Detect mode can be used with either one or two probe inputs.
NOTE: Contact Closure (CC) sensor boards do not have Classify/Detect modes.
IX.
Selecting Output Ports
A sensor board’s output ports are the three lines of communication from it to the
Encoder/Transmitter board. Alarm pulses generated by the sensor board are (or are
not) sent to the Encoder/Transmitter board depending on which PORT SELECT
switches are turned on. To turn a switch on, press it down towards the circuit board.
Only select one Port for each function. Do not select duplicate Ports for different
functions as this prevents the alarm from being sent. To prevent a particular function
from being sent, do not select a Port for it. The Contact Closure (CC) switches are only
used when a normally open contact closure probe is connected to J1 on LCT-DS and
LCT-SS models. The pictures on the next page show the PORT SELECT switch
assignments for all models except the LCT-CC which do not have selectable ports.

X. LCT-CC Contact Closure Transmitters
The LCT-CC provides three sets of inputs for external devices that signal detected
activity by means of opening or closing a switch. Unlike other LCT-XX models, there
are no sensor board switches to set with these transmitters. Instead, alarm pulses are
automatically assigned to the Ports associated with the inputs. For each of the three
Ports, there is a normally closed pair of contacts in J1 and a normally open pair of
contacts in J2.

XIII. Deployment Tips
A. LCT-XX
•
When changing batteries or settings, it is important to make sure that
the case O-ring and mating surface are clean. Debris between the Oring and mating surface creates a leak path which allows water to enter
the unit.
•
The LCT-XX should only be buried deeply enough to cover the input
connectors. If it is buried too deeply, the antenna’s signal is
significantly attenuated.
•
Maximum transmit range is achieved when the LCT-XX has an
unobstructed line of sight to the receiver’s or repeater’s antenna.
When circumstances permit, use coax to remote-mount the antenna in
an elevated location to improve performance in difficult terrain.
B. Seismic Probes (SPS-21)
•
Although the probe’s cable is shielded, strong sources of
electromagnetic energy can be conducted to the LCT-XX’s seismic
amplifiers. Excess coiled cable should be placed under the unit to
avoid picking up alarm transmissions. The unit should also be
deployed away from other strong EM sources such as high-power
transmission lines, power transformers, and radio towers.
•
To reduce the possibility of non-target alarms, deploy probes well away
from sources of ground noise such as: heavy traffic; windblown trees,
signs, etc.; pumps, compressors, and other machinery; livestock and
animal trails.
•
Vibrations travel farther and retain more energy in hard or rocky
ground. If the probe seems too sensitive with the LCT-XX on the
lowest gain setting (switches 1 and 2 down), one or more of the
following techniques should be used:
o Use a shorter spike on the probe or eliminate it altogether.
o Dig an oversized hole for the probe an fill it with a softer
material like potting soil.
o Connect an attenuator cable between the probe cable and
transmitter to cut the signal in half.
o Connect additional probes end to end to form a line string.
Line strings may be composed of up to six probes.
•
Vibrations dampen out quickly soft or wet soil. To increase the probe’s
sensitivity, replace the probe’s spike with a longer one or with a length
of 3/8”-16 all-thread.
LCT-XX L5 USER’S MANUAL
Page 16 of 19
C. Dual-Axis Magnetometer Probes (MS-10)
•
Magnetic probes generate an alternating magnetic field and react to
ferrous metals and other magnetic fields moving within that field. If the
magnetometer is deployed above ground, it must be rigidly secured to
prevent movement. Whether above or below ground, the MS-10 must
not be deployed near sources of interference such as: windblown
fencing, guy wires, signs, etc.; power lines and transformers; and
electric motors.
•
Under certain circumstances, the temperature of the MS-10’s may be
elevated above its operational limit of 60°C (140F°). This typically
occurs during very hot weather and when the MS-10 is in direct
sunlight or is shallowly buried in an unshaded area. If the probe gets
too hot, false alarms may be generated. To eliminate false alarms,
bury the probe a few inches deeper or deploy it in a shaded location.
D. Passive Infrared Probes (PIR)
•
Passive infrared probes react to changes in temperature in the
direction they are pointed. False alarms may be generated if the probe
is pointed where there is background or animal movement, heat
waves, or excessive incident light.
•
It is important that the probe be rigidly mounted so that its own
movement does not cause false alarms.
•
NOTE: under no circumstances should an infrared probe be pointed
where it will see direct or strongly reflected sunlight.
