Redback® A 4574 Alert/Evac/Chime Tone Generator
12.0 Optional Remote Wall Plates
There are two optional remote wall plates which can be connected to the A 4574 for remote triggering of the Alert, Evac-
uation and Bell tones and for remotely cancelling any tones which may be active.
12.1 A 2078B Remote Plate
The A 2078B wall plate provides a remote means of trigger-
ing the Alert and Evacuation tones and the cancel function.
Connection is made to the A 4574 via a minimum of 7 wires
as shown in Fig 9.
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.
The Alert/Evac/Cancel switches on the A 2078B wall plate are
connected to the corresponding contacts on the rear of the
A 4574. While the Alert and Evac LEDs on the wall plate are
connected to the Alert 24V and Evac 24V outputs of the
A 4574. The cancel LED is not connected. A mimimum of
seven wires can be used if the ground connections of the
Alert and Evac 24V outputs are linked and if the Alert/Evac
and cancel switch grounds are linked together (see Fig 9).
