The A 2078B wall plate provides a remote means of triggering the Alert and Evacuation tones and the cancel function. Connection from the A 2078B is made to the A 4500B via a minimum of 6 wires. Connection is made from the A 2081 to the A4500B via a minimum of 8 wires. 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 gauge cable, which reduces the voltage drop across this distance and ensures the
switch LEDs illuminate. The Alert/Evac/Chime/Cancel switches on the wall plate are connected to the corresponding contacts on the rear of the A4500B. While the Alert, Evac and Bell LEDs on the wall plate are connected to the Alert, Evac and Bell 24V outputs of the A4500B. The cancel LED is not connected. A minimum of six wires can be used on the A 2078B if the ground connections of the Alert and Evac 24V outputs and the Alert/Evac and cancel switch grounds are linked together. A minimum of eight wires can be used on the A 2081 if the ground connections of the Alert, Evac and Bell 24V outputs and the Alert/Evac/Chime and cancel switch grounds are linked together.

Two snap-on covers are provided, allowing you to choose a style that suits your installation.
