Auxiliary relay circuits
The control panel operates the auxiliary contacts when the confi gured event is received
from the system.
The auxiliary relays 1 and 2 contacts can be used to control external equipment, such
as an automatic dialer that makes the call for fi re fi ghting action. The relays can be
individually re-confi gured to operate with either fi re, fault or disablement event in the
system.
The relay operation can also be delayed by up to 10 minutes and can be set up
to operate in a normally energised or de-energised state. The contacts should be
powered from an independent power supply, where required.
