E-4 Appendix E – Alarm Report Monitor (ARM2000)

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 (LG

Cell

, 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.

ARM2000-RU (Remote Unit) Installation

The ARM2000-RU is rack mounted in the same rack as the LG

Cell

Main Hub(s).

This remote-ARM unit has an “octopus” cable that enables it to monitor up to 8

Cell

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.
