A 2081 Remote Plate - Redback A 2078B Operating Manual

Setup

3.2 A 2081 Remote Plate

The A 2081 wall plate provides a remote means of triggering the Alert, Evacuation and Bell tones and the cancel function.
Connection is made to the A 4500A via a minimum of 9 wires as shown in Fig 3.2B.
If standard Cat5 cable is used for the wiring, the plate can be located up to 30m away from the main unit. This can be
increased to 100m away using heavier guage cable, which reduces the voltage drop across this distance and ensures the
switch leds illuminate.
