A 2081 REMOTE WALL 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 4574 via a minimum of 8 wires as
shown in Fig 10. If light duty cable is used for the wiring (such as
Cat5e/6 cable), 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 LED's illuminate.
The Alert/Evac/Chime/Cancel switches on the A 2081 wall plate
are connected to the corresponding contacts on the rear of the
A 4574. While the Alert, Evac and Bell LEDs on the wall plate are
connected to the Alert, Evac and Bell 24V outputs of the A 4574.
The cancel LED is not connected. A mimimum of eight wires can
be used if the ground connections of the Alert, Evac and Bell
24V outputs and the grounds of the Alert/Evac/Chime and cancel
switches are linked together (see Fig 10).
