Remote Wall Plates; A 2078B Remote Plate - Redback A 4565B Operating Manual

Redback® A 4565B Evacuation Controller

3.0 REMOTE WALL PLATES

There are five remote wall plates which can be connected to the A 4565B for remote triggering of the Alert, Evacuation,
Bell, Fire Test and Fire Alarm tones and for remotely cancelling any tones which may be active.

3.1 A 2078B Remote Plate

The A 2078B wall plate provides a remote means of triggering the Alert and Evacuation tones and the cancel function.
Connection is made to the A 4565B via 6 wires as shown in Fig 3.1B. Remote triggering is only available when the A
4565B is in "Auto" mode which is selected by the key switch on the front of the A 4565B. 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.

A 2078B REMOTE WALL PLATE
The Alert/Evac/Cancel switches on the A 2078B wall plate are
connected to the corresponding contacts on the rear of the
A 4565B. While the Alert and Evac LEDs on the wall plate are
connected to the Alert 24V and Evac 24V outputs of the
A 4565B. The cancel LED is not connected. A mimimum of
six wires can be used if the ground connections of the Alert
and Evac 24V outputs and the Alert/Evac and cancel switch
grounds are linked together (see Fig 3.1B).
If the Alert and Evac switches on the A 2078B are pressed
when the A 4565B main unit is in "Manual" or "Isolate"
mode, nothing will happen. If the Alert and Evac switches are
pressed on the A 4565B while in "Manual" mode the Alert
and Evac switches on the A 2078B wall plate will illuminate.
