Installation Guide

External Alarm
Burglary, fire or other external alarm can be used in the repeaters.
Optical or acoustic alarm can also be connected to the repeaters.
External alarm sensors and alarm signals are connected to the P33 alarm
port located to the left in the cabinet (see Figure 2-12).
The P33 alarm port is described in the Connection Ports section on
page 2-18.
Use a 15 pole D-sub male connector for this connection.
The cable for this installation is taken through a strain relief bushing at
the bottom of the repeater.
For a repeater without a CU board, i.e. BMU, external alarm is connected
to the P109 port on the FON board. The P109 port is described in the
FON - Fiber Optic Node Board section in the AR Repeaters, User’s
Manual, Chapter 5.
Door Open Alarm
A door open alarm can be used in all repeater types that have a CU
board, i.e. all types except for BMU. This is arranged with a door switch
connected to the P28 port (see Figure 2-12). The P28 port and the
connection is described in the Connection Ports section on page 2-18.
