LGCell Installation
System Requirements
An LGCell system has location, space, power, and safety requirements for
installation. The Dual Band LGCell requirements for space and power are different
from those for a single-band system and are noted below.
System Location
The LGCell Main Hub and Expansion Hub mount into a standard 19" equipment
rack in a wiring, telecom, or electrical closet, which may contain other Ethernet,
telephony, or miscellaneous equipment.
•
•
Standard wiring closet temperatures: 0-45° C
Does not require special air conditioning
Space Requirements
The LGCell Main Hub and Expansion Hubs are installed into a standard 19” rack.
•
•
•
The Main Hub height is 1.7” (44.5 mm). The Dual Band Main Hub is 3.5”
(88.9 mm) high.
The Expansion Hub height is 1.7” (44.5 mm). The Dual Band Expansion Hub
is 3.5” (88.9 mm) high.
Allow at least one inch (25 mm) clearance between each hub, between any
existing equipment in the rack, and between the bottom shelf of the rack and
the hub.
Power Requirements
The LGCell requires AC voltage/current. LGC Wireless recommends connecting it
to a UPS (Uninterruptable Power Supply), which may exist in the wiring closet.
Dual-Band equipment requires twice as much power as single-band equipment.
•
•
•
•
LGCell operates with 88-264 VAC 50/60 Hz.
The Main Hub uses a maximum of 1.6 A of electrical current.
The Expansion Hub uses a maximum of 1.6 A of electrical current.
The RAUs are powered from the Expansion Hubs via the UTP/STP cable and
they use 12V DC.
4-3
Underwriters Laboratory Installation Guidelines
Use the following guidelines when rack mounting the LGC Cell:
Do not exceed the maximum ambient air temperature of 45° C during
operation. Provide sufficient airflow and cooling within the rack to prevent
heat build-up from exceeding this limit.
Be careful when servicing these products. If you are removing the system from
the rack, turn it off and remove the power cord first. There are no user
serviceable parts inside the hubs or RAUs.
Do not compromise the amount of airflow required for safe operation of the
equipment when installing it in a rack. Both the Main Hub and the Expansion
Hub draw in air on the left side and exhaust heated air at the rear. The hubs
pass approximately 6 cu. ft. of air per minute through themselves and only
dissipate a maximum of 25 watts of heat from their internal circuitry.
The AC input current consumption of the hubs is rated at 1.6 A at 110 VAC.
The internal power supply has internal fuses that are not user replaceable.
Consider the worst-case power consumption shown on the product labels when
provisioning the rack’s AC power source and distribution.
Fiber Port Safety Precautions
Suggested safety precautions for working with LGCell Fiber Ports follow. For
information about LGCell compliance with safety standards, see Appendix C –
Compliance Information.
•
Viewing fiber: Observe the following warning about viewing fiber ends and
ports.
Do not stare with unprotected eyes at the connector ends of the fibers or
the ports of the hubs. Invisible infrared radiation is present at the front
panel of the Main Hub and Expansion Hub. Do not remove the Fiber
Port dust cover unless the port is in use. Do not stare directly into a Fiber
Port.
4-4
•
Test fiber cables: When you use test fiber optical cables, connect the optical
power source last and disconnect it first.
•
Fiber ends: Cover any unconnected fiber ends with an approved cap. Do not
use tape.
•
Broken fiber cables: Do not stare with unprotected eyes at any broken ends of
the fibers. Report any broken fiber cables and have them replaced.
•
Cleaning: Use only approved methods for cleaning optical fiber connectors.
•
Modifications: Do not make any unauthorized modifications to this fiber
optical system or associated equipment.
LGCell Installation
•
Live work: Live work is permitted on the LGCell as it is a Class 1 hazard.
•
Signs: No warning signs are required.
•
Test equipment: Use Class 1 test equipment.
Cable and Connector Requirements
The LGCell equipment operates over standard TIA/EIA 568-A specification,
Category 5 (CAT 5), or better, Unshielded Twisted Pair (UTP) or Shielded Twisted
Pair (STP) and standard 62.5µm/125µm Multi-Mode Fiber cable (MMF), at a
wavelength of 1300 nanometers (nm).
These cables are widely used industry standards for Local Area Networks (LANs).
The regulations, guidelines, and standards for cable installation are identical to
those specified by the TIA/EIA 568-A standard for LANs. See Appendix B – TIA/
EIA 568-A Cabling Standard.
LGC Wireless recommends Plenum rated CAT 5 UTP/STP and MMF cable and
connectors for conformity to building codes and standards.

Alarm Report Monitor
A separately orderable option for use with LGCell, the Alarm Report Monitor is an
alarm monitoring, reporting, and remote control system. Up to 255 remote-ARM
monitoring units can monitor up to 2,040 LGCell systems. Each remote-ARM unit
communicates with the ARM software through a dial-up modem connection, using
an external or internal modem. A database of these devices is set up in a PC, with a
unique address for each device.
The ARM supports multiple users and tracks responsibility through log-in and logout procedures, using four security levels to protect critical system functions. It
features a graphic color status display, remote system reset control, alarm history
and control logs, security code management, and journal printer and paging options.
For ARM installation instructions, see Appendix E – Alarm Report Monitor

Connectivity
Connecting Multiple LGCell Systems
Connecting multiple LGCell systems increases the total number of Remote
Antenna Units (RAUs). Multiple LGCells can be stacked to increase the total
number of RAUs through the use of power combiner/dividers.
LGC Wireless provides Integration Modules which may be used with the LGCell
to efficiently centralize additional radio capacity inside a facility. These Modules
provide the connection between the radios for the facility and the LGCell system.
Because the Integration Modules distribute all available radio capacity
automatically among all antennas within a cell, available capacity is dynamically
allocated throughout the entire coverage area, thus providing an improved grade of
service without the need to conduct ongoing traffic monitoring and analysis.
Specific installation information on all available Integration Modules may be found
in the Integration Module Installation and Reference Manual.
Connecting two LGCells
Connecting two LGCells increases the total number of RAUs from 16 to 32. A 2x1
or 2x2 hybrid power combiner/divider is required (see graphic below).

From LGCells to Hybrid Power
Combiner/Divider
Connect the DUPLEX, FORWARD, or
REVERSE connector of one of the Main
Hubs to an input/output port on the power
combiner/divider using an N-male to Nmale coaxial cable jumper.
To Roof-Mounted Antenna, Repeater,
or MBS
Connect the combined port of the power
combiner/divider to a roof-mounted antenna,
repeater, or MBS using an N-male to N-male
coaxial cable jumper.
Connect the DUPLEX, FORWARD, or
REVERSE connector of the second Main
Hub to the second input/output port on the
power combiner/divider using an N-male to
N-male coaxial cable jumper.
Check Main Hub LEDs
After connecting the LGCells, check all Main Hub LEDs to ensure that the
system is operating properly.
Connecting More Than Two LGCells
Repeat this procedure to connect any number of LGCell systems. For three systems,
use a 3x1 power combiner/divider, and so on.
Connecting LGCell to Base Stations, Microcells, or
Picocells
One or more LGCell systems can connect with any base station, microcell, or
picocell. Before connecting an LGCell system to one of these, confirm the
following items:
•
Connector type (LGCell uses N-type connectors)
•
Power distribution (LGCell supports either duplex or simplex)
•
Maximum power output (dBm) (Do not exceed the maximum input power into
the Main Hub. If the input power is too high, an attenuator might be required.)
For more information about connections to microcellular base stations or picocells,
including connections to multiple base stations, see the Integration Module
Installation and Reference Manual.

Make sure that there is a reasonable amount of power at the
input of the Main Hub. Measure the output power of the
coaxial cable using a power meter.
The LGCell is intended for a different frequency band.
Verify that your system corresponds to the desired
frequency spectrum (for example, 800 MHz, 1800 MHz, or
1900 MHz). Check the part number of each unit.
The LGCell is factory set for different bands of operation.
Please be sure you have the proper band.
The system gain is lower than
specification.
The optical fiber connector is dirty. Clean the fiber STconnector, using the manufacturer’s recommended cleaning
procedure.
There are two types of Multi-Mode Fiber (MMF), 62.5/
125 µm and 50/125 µm. Make sure the vertical run MMF is
the 62.5/125 µm type of fiber.
Remote Antenna Unit (RAU)
power LED (green LED) stays
off after you plug in the twisted
pair cable.
The Expansion Hub provides power to the RAU. Make sure
the Expansion Hub is on.
The LGCell performance is
intermittent when you use it for
the CDMA application.
The uplink and downlink gain is not balanced. A CDMA
system performs active power control between the base
station and the mobile unit. It is important to maintain a
balanced link from the base station ports to the RAU ports
(equal uplink and downlink gain) to optimize the
performance of the LGCell.
Make sure that the twisted-pair (TP) cable wiring conforms
to the TIA/EIA 568-A standard. (For information about the
standard, refer to Appendix B – TIA/EIA 568-A
Cabling Standard.) Use a standard local area network
(LAN) cable tester to perform this test. Possible errors are
wrong wiring and/or cable length.

Diagnostic Procedures
Use the following table when diagnosing system problems. While troubleshooting,
you can copy the blank table on page 12 and use it to record the LED colors on the
Main Hub, the particular Expansion Hub indicating a fault, and the RAUs
connected to it. This is necessary because the Main Hub, Expansion Hubs and
RAUs might be geographically distributed.
To determine where the fault might be
6-8
Go to the Main Hub and record the LEDs. The Main Hub indicates which
Expansion Hub may be faulty by lighting one of its port LEDs red.
Go to the Expansion Hub attached to the port that has a red LED.
Record that Expansion Hub’s LEDs. The Expansion Hub indicates which
RAU(s) may be faulty by lighting its antenna LED red.
Go to the RAU(s) connected to the Expansion Hub port indicating a fault.
Record the error.
Compare your filled in table to the Diagnostic Table below and begin
troubleshooting according to the notes indicated for your situation.

•
6-10
If the cable is OK, replace the RAU.
The Expansion Hub is not properly receiving the synchronization signal from
the Main Hub.
• The MMF cable connection might not be good or if system was working,
the MMF downlink cable is pulled out or cut. Switch MMF cables.
•
If the problem persists, switch to a different Main Hub port. If this solves
the problem, the Main Hub port is malfunctioning.
•
If the problem persists, there is an Expansion Hub problem.
•
If switching MMF cables is not practical, switch the uplink and downlink
pairs. (A connection error may have been made when connecting the Main
Hub UP port to the Expansion Hub UP port, and similarly for the DOWN
ports.)
•
If the Expansion Hub SYNC LED turns green, one of the MMF cables was
bad or the connection between the Main Hub and Expansion Hub was done
incorrectly. If both are bad, this test will not help. Switch to a different
Main Hub port.
The Expansion Hub is not properly receiving the synchronization signal from
the Main Hub.
Too much loss on downlink MMF. Might be due to MMF pairs not attached to
the proper connector.
•
Check that the “down” cable end is in the DOWN port connector on both the
Main Hub and on the Expansion Hub. Same for the “up” cable end and
connectors for the UP port.
•
If the problem persists, check the integrity of MMF cable using an Optical
Time Domain Reflectometer. If the fiber is faulty, replace it.
•
If the MMF cable is OK, try using a different Main Hub port.

Common Problems, Troubleshooting, and Frequently Asked Questions
Frequently Asked Questions
The following list provides answers to some frequently asked questions about
LGCell:
What is the LGCell Distributed Antenna System?
The LGCell Distributed Antenna System (DAS) contains multiple low-power
radiating elements that are deployed around indoor facilities to improve
coverage and capacity. The unique, patented architecture of the LGCell DAS
provides an inexpensive solution to the cellular and PCS provider for coverage/
capacity upgrades and private microcell applications.
What is twisted pair cable? Will it pick up spurious emissions?
Twisted pair (TP) cable is the standard cable that you find at the back of your
computer for the network hookup. TP cable is the most ubiquitious cable in any
office building. Furthermore, TP cable is inexpensive and easy to install. The
twisting nature of the cable creates a transmission line for efficient signal
transfer and rejection of spurious emissions The LGCell uses a state-of-the-art
common-mode rejection device that reduces pickup of spurious emissions on a
TP cable by a factor of 10,000.
Can a single LGCell simultaneously support multiple access standards (such
as 800 AMPS/TDMA?
Yes. The LGCell is a frequency selective product. The LGCell system is
transparent to the protocol that the base station and mobile unit use. You can
view the entire system with all the cables together as a frequency selective
repeater with a specified gain.
What is the bandwidth of the LGCell?
LGCell selects from the RF bandwith, which can help prevent amplification of
an unwanted signal, such as a competitor’s signal. Refer to the data
specifications for the RF bandwith of the system. Another interpretation of
bandwidth is the amount of data that the LGCell system can transmit. The
microcellular or macrocellular base station to which the LGCell is connected
limits the bandwith or capacity of the LGCell, which is a transparent system.
Total, composite output power and spurious emissions are the only constraints
that limit the amount of channels that an RAU can radiate. Furthermore, the
LGCell system shall not limit the data rate of the modulation transmitted
through the system.
Can the LGCell support multiband operation?
The LGCell provides a wide variety of single-band products, including the U.S.
800 MHz, European GSM 900, DCS 1800, Korean PCS 1800, U.S. PCS 1900
systems, and iDEN. You can use these systems together to provide multiband
services. In addition, LGCell has a Dual Band 900/1800 system available.
6-13
6
Can the LGCell system share the same UTP Category 5 Cable with the
Ethernet network?
No. The LGCell system can use the existing unused cabling inside the building;
however, you cannot use the same cable to connect an RAU and a computer.
What is the minimum power input to the Main Hub?
The coverage area of an RAU is directly related to the input down link power
at the Main Hub. Therefore, an input power that generates an output power of
0dBm per channel optimizes the coverage area of an RAU.
What is the minimum detectable power of an RAU?
The minimum detectable power of system with 1 RAU is -114 dBm in a 30 kHz
bandwidth, -106 dBm in a 200 kHz bandwidth, and -98 dBm in a 1.25 MHz
bandwidth, without taking into account the processing gain of different access
standards.
What is the difference between connecting the LGCell to a roof-mounted
antenna and to a microcellular base station?
Connecting the LGCell to a roof-mounted antenna increases the coverage of the
indoor environment. Connecting the LGCell to a microcellular base station
improves both the coverage and the capacity in the building and might also
provide a private wireless office application for the customer.
10 Does each Main Hub require a separate coaxial feed to the base station?
A typical RF input power per channel to the Main Hub is 0 dBm. This provides
a lot of margin (link budget margin) for interfacing with antennas through a
base station that typically has an output power of 20 dBm. Therefore, a power
combiner/splitter might be installed between the MH and the base station. This
enables one base station to connect to multiple Main Hubs. For details, refer to
Section 2, LGCell Equipment.

Appendix
– TIA/EIA 568-A Cabling Standard
This appendix is a summary of the TIA/EIA 568-A Commercial Building
Telecommunications Cabling Standard.
The TIA/EIA 568-A commercial building cabling standard addresses the need for
a common criterion covering cabling in commercial buildings. The standard was
drafted to ensure support for a wide variety of applications, devices, and vendor
products.
The TIA/EIA 568-A standard assures a flexible cabling scheme which permits the
planning and installation of communications cable without prior knowledge of the
user's needs. This is especially valuable for new building construction and
renovation where it is less costly and less disruptive to install a universal cabling
system prior to occupancy.
The need for a building cabling standard was recognized in the early 1980s. It
resulted from the changes brought on by new technologies. The purpose of the
original drafting committee was to provide a non-proprietary cabling system for
both new and existing facilities.
In 1985, the Computer Communications Industry Association approached the
Electronic Industry Association (EIA) in regard to the market's confusion over
cabling systems. The EIA and later its offspring, the Telecommunications Industry
Association (TIA), addressed this via technical working groups comprised of
industry participants. The resulting standard 568 addressed performance and safety
issues related to technology and utilized many recognized and proven standards.
The TIA/EIA 568-A standard defines the categories of UTP cabling, the categories
of connecting hardware, patch cables, and provides guidelines on cabling practices.
The TIA/EIA 568-A standard describes six sub-systems within a facility
telecommunications cabling system summarized below. (This is intended as a
summary only and is meant to provide a better comprehension of the standard. The
complete TIA/EIA 568-A standard is available for purchase. Call 1-800-854-7179.)
Horizontal Wiring
The horizontal cable is the portion of the cabling system which extends from the
work area outlet to the telecommunications closet. The horizontal cabling is a star
topology, with a maximum cabling run of 90 meters (295 feet), independent of
media type.
Voice
4-pair 100 ohm UTP cable
Data
4-pair 100 ohm UTP/STP
2-pair 150 ohm STA
62.5/125 µm fiber optic cable
The horizontal cable amounts to the greatest quantity of individual cables in the
building. Although the TIA/EIA 568-A standard helps limit cabling options,
consideration should be given to media type in order to support possible future
needs. The cable selected should accommodate more than one network planning
period.
Backbone Wiring
The backbone cabling provides the interconnection between the telecommunications closets and the equipment rooms and entrance facilities. The
backbone cabling is also a star topology with the maximum cable length being
media and applications dependent.
The backbone cable is typically second to horizontal cables in terms of amount of
cable deployed. The cable selected should accommodate a minimum of one to
several network planning periods.

Work Area
The work area interconnects the horizontal cabling at the wall outlet to the desktop
devices. The maximum allowable distance for patch cables is three meters (9.8
feet), based on the cable being of the same type as the horizontal cable.
Telecommunications Closet
The telecommunications closet is the area in a building dedicated to
telecommunication equipment. The functions which take place in the closet include
the interconnection point between horizontal and backbone cabling systems, the
interconnection of two or more backbone cabling systems, and/or the
interconnection of the entrance facility to the overall telecommunications cabling
system.
B-3
Equipment Room
The equipment room is the area in a building where telecommunications equipment
is located. Parts of or all of the telecommunications cabling system terminate here.
Entrance Facilities
The entrance facility is where outside telecommunications service enters the
building, and interconnects with the building's internal telecommunications
systems. In a campus or multi-building environment, the entrance facility may also
contain the building's backbone interconnects.
Unshielded Twisted Pair Cable Termination
All UTP (Unshielded Twisted Pair) shall be terminated according to the TIA/EIA
568-A standard.

Part 2 of IEC 60825 provides requirements and specific guidance for the safe use of
optical fiber communications where optical power may be accessible at some
distance from the optical source. In this part of IEC 825, light emitting diodes
(LED’s) are included whenever the word “laser” is used.
Description of LGCell System
The LGCell is a distributed antenna system. It consists of three main components.
A Main Hub, which is connected by dual mode fiber optic cables to one or more
Expansion Hubs. Each Expansion Hub is connected by UTP CAT 5 cable to a
Remote Antenna Unit. Because LED’s are used to send a signal over the fiber optic
cable, the LGCell is covered under the IEC 60825 specification.
Requirements under IEC 60825
Under IEC 60825, LGC Wireless is required to determine the Class of operation of
the LGCell system, the Hazard level of the LGCell system and any special
instructions that must be included in an operators manual as well as any warning
labels that may be required on the LGCell system.
The LGCell is covered only under these definitions of section 3 of 60825.
3.2 enclosed system: A system in which, during normal operation, the optical
radiation is totally enclosed, by light proof cabinets, components, total internal
reflection or optical fiber cables and connectors.
3.3 end user: The person or organization using the optical fiber communication in
the manner the system was designed to be used. The user cannot necessarily control
the power generated and transmitted within the system.
3.4 hazard level 1: A hazard level 1 is allocated to any part within an optical fiber
communication system at which, under reasonably foreseeable circumstances,
human access to laser radiation in excess of the accessible emission limits (AEL) of
class 1 for the applicable wavelengths and emission duration will not occur.
3.10 light emitting diode (LED): Any semiconductor device which can be made
to produce electromagnetic optical radiation in the wavelength range from 180nm
to 1mm. (The optical radiation is produced by the process of spontaneous emission,
although some stimulated emission may be present.)
3.13 location with controlled access: A location where access to the protective
housing (enclosure) is controlled and is accessible only to authorized persons who
have received adequate training in laser safety and servicing of the system involved.
Examples include optical cable ducts and switching centers.
C-6
Appendix C – Compliance Information
3.14 location with restricted access: A location where access to the protective
housing is restricted and not open to the public. Examples include industrial and
commercial premises, PBX rooms, computer system rooms, and optical test sets.
Distributed fiber networks may pass through unrestricted public areas, restricted
areas within premises, as well as controlled areas or they may be deployed entirely
within restricted business premises.
3.18 optical fiber communication system: An engineered assembly for the
generation, transference, and reception of optical radiation arising from lasers in
which the transference is by means of optical fiber for communication purposes.
3.19 reasonable foreseeable event: An event, the occurrence of which under given
circumstances can be predicted fairly accurately, and the occurrence of which is a
possibility. Examples of reasonably foreseeable events might include the following:
fiber cable break, optical connector disconnection, operator error or inattention to
safe working practices. Reckless use or use for completely inappropriate purposes
is not to be considered as a reasonably foreseeable event.
Installation Notes
The LGCell is covered under these parts of section 5 of 60825
5.2.1.3 Test Equipment: During installation or testing of an optical fiber cable or
system, only test equipment of laser Class 1 should be used.
5.2.1.5 Installation Rules: Each person engaged in the installation or service of an
optical fiber cable communication system should observe all rules, procedures and
practices established for the safe operation of optical fiber communication systems.
Evaluation of LGC System
The LGCell is covered under Annex A of 60825
The LGCell system is a self contained product that contains an optical fiber
communication system that would be safe under normal operating conditions
because the optical radiation is totally enclosed and contained under intended
operation. However, because of the extended nature of the system, the optical
power may be accessible a kilometer from the optical source. The LGCell system
contains LED's, which are the source of radiation covered under IEC 825. Usually
a whole fiber optical communication system would not be classified under IEC 8252 in the same way required under IEC 825-1. This is because, under intended
operation, the optical power is totally enclosed, and it could be argued that an
interpretation of IEC 825-1 would give a class 1 to all systems, which may not
accurately reflect the hazard potential of some systems. If the emitter can be
operated separately, it should be classified according to IEC 825-1. However, the
power output level of the LGCell system is so low that it always falls into the class
1 hazard level even under 100% modulation conditions. The absolute maximum
allowed at 1300nm is +9.5 dBm. The absolute maximum accessible output of the
C-7
LGCell fiber optic system is -11.5 dBm. Therefore there is no restriction as to
location of use of the LGCell system and there is no labeling requirement.
Suggested Work Practices
The LGCell is covered under these parts of section D7 of 60825
The following working practices are suggested for working on the LGCell system:
C-8
•
Viewing Fiber: Do not stare with unprotected eyes at the connector ends of the
fibers or the ports of the hub.
•
Test Fibers Cables: When using test fiber optical cables, the optical power
source shall be the last to be connected and the first to be disconnected.
•
Fiber ends: Any unconnected fiber ends should be covered with an approved
cap. Do not use tape.
•
Broken Fiber Cables: Do not stare with unprotected eyes at any broken ends
of the fibers. Report and have any broken fiber cables replaced.
•
Cleaning: Use only approved methods for cleaning optical fiber connectors.
•
Modification: Do not make any unauthorized modifications to this fiber
optical system of associated equipment.
•
Live work: Live work is permitted on the LGCell as it is a class 1 hazard.
•
Signs: No warning signs are required.
•
Test Equipment: Use class 1 test equipment.

ARM2000 System Basics
The ARM2000 system is an alarm monitoring, reporting, and remote control
system. Up to 8,160 individual alarm points can be monitored, displayed and logged
by the system. The system consists of up to 255 remote-ARM monitoring units that
can monitor up to 2,040 LGC systems (LGCell, PCS Extender, Fiber Extender) and
a Pentium PC running the ARM software.
These remote-ARM units communicate with the ARM software through dial-up
modem connections. Each remote-ARM unit can use an external or internal
modem. A database of these devices is set up in the PC, each device having a unique
address. This address is set on the device and programmed into the PC using the
Device Setup utilities of the software.
The next figure illustrates both the direct connection of a single ARM unit and
multiple units connected via a dial network.
Multiple Remote-ARM Over Dial-up Network
Remote ARM with Internal Modem
Dial-up
Network
Remote ARM with Internal Modem
ARM2000-RU (Remote Unit) Installation
The ARM2000-RU is rack mounted in the same rack as the LGCell Main Hub(s).
This remote-ARM unit has an “octopus” cable that enables it to monitor up to 8
LGCell Main Hubs. The ARM unit needs to be within 4 feet of each Main Hub that
it will monitor due to the cable length.
The ARM unit has an external power supply that requires a 110 VAC receptacle.
Connect the power to the ARM unit after all cable and telephone connections are
completed.
E-4
Appendix E – Alarm Report Monitor (ARM2000)
Modem Connections
Communications to or from the remote ARM can be configured in either of two
ways:
•
Internal modem (inside remote-ARM unit)
The internal modem must be a North American qualified modem for use in
telephone networks that use North American standard call progress tones. This
modem is inside the remote-ARM unit and requires an analog phone line
connection with an RJ-11 male connector. Connect the phone line to the port
marked “Line” in COM1, at the back of the remote ARM.
•
External modem (via RS-232 COM1)
LGC Wireless recommends a US Robotics External modem qualified in the
country of use. To install this modem, you need a DB-25 to RJ-45 converter
cable and a cable with RJ-45 male connectors on both ends.
If you are in a country that does not use North American standard call progress
tones, you need to use an external modem with the ARM2000-RU unit.
If you use the US Robotics External modem, you need to prepare the modem with
initialization commands before you use it, as “Preparing the PC Modem” on page 7
describes. Take the following steps to install the modem:
Connect the phone line to the phone line marking at the rear of the modem.
If you choose to be notified by a phone ring of an incoming call, then connect
the phone to the phone marking at the rear of the modem via RJ-11 male
connectors on both ends.
Connect the DB-25 to RJ-45 converter at the rear of the modem.
Run the other end of the RJ-45 cable to the RS-232 COM1 port at the rear of
the remote ARM.
Alarm Cable Connections
To connect the LGCell Main Hub(s) to the remote ARM, use the two-to-eight-port
connector cable. Make the following connections to monitor the following alarms:
Connector

Output
Remote Reset from ARM unit
Alarm Cable and Connectors
Test Setup
After the ARM unit is powered up, the unit should be reset and ready for
communicating to the PCARM system for final programing.
When the ARM is powered, wait 15 seconds and then press the TEST button on the
left front of the unit. All 16 circuit alarm LEDs on the front panel should light and
toggle to green momentarily. If this does not occur, power down the ARM unit for
15 seconds and start over.
The LED final state should be green to indicate a proper connection and a no-fault
condition for each Main Hub that is also powered up. Each Main Hub has 2 LEDs
assigned to it. Alarm circuits that do not have an “octopus” cable connected will be
red.
E-6
Appendix E – Alarm Report Monitor (ARM2000)
PCARM Programming Information
If multiple ARM200-RU units are installed that will be controlled by one PCARM
system, then each ARM200-RU unit must be configured with a unique device ID
(1-255) for programming by the PCARM system. Each ARM unit must have a
different device ID if it will be controlled by one PCARM system. There is a label
on each ARM unit that indicates what device ID it has be configured for. The device
number and which Main Hub(s) it has been connected to, is important information
that must be provided to the person programming the PCARM.
PCARM Installation for ARM2000
