Auxiliary relay circuits
Auxiliary relay circuits
The control panel operates the auxiliary contacts when the configured 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 fire fighting action. The relays can be
individually re-configured to operate with either fire, 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.
PANEL
Factory default:
Aux relay 1 is normally de-energised and operates with a
fire event without delay.
Aux relay 2 is normally energised and de-energises with a
fault event without delay.
Note: Aux relay 2 has been shown in the above diagram in
its de-energised state, which is the state when there is
no power to the panel.
