Redback® A 4500C Evacuation Timer with Network Access
4.2 A 4578, A 4579, A 4581 and A 4581V Remote Plates (U/UTP Cat5/6 cabling)
The A 4578, A 4581 and A 4581V wall plates provide a remote means of triggering the Alert, Evacuation and Bell (A 4581
and A 4581V only) tones and the cancel function.
The A 4579 wall plate provides a way of remotely isolate the timing functions of the A 4500C. This has the same function-
ality as the Isolate switch on the front of the timer.
The wall plate switches are momentary operation and must be pressed for up to 3 seconds to activate, and have protective
"flip up" covers to prevent accidental operation.
Connection is made to the A 4500C via standard Cat5e cabling as shown in Fig 3.2 There are two RJ45 ports on the rear
of the wall plates, either of which can be used. Only one A 4578, A 4579, A 4581 or A 4581V wall plate is allowed to be
connected to the A 4500C via the "To Wall Plate" RJ45 port.
If the wall plates have a connection problem with the A 4500C main unit, the LED on the wall plate will flash.
