Outputs – Volt Free Relay (TB5)
There are two voltage free relay outputs, the Remote output, and the Fault output.
5.4.1 Fire Output Relay
The Fire Output Relay has 1A 30VDC unsupervised voltage free single change over contacts that
are activated when any zone circuit reports an alarm condition. The front panel indicator “Fire Output
On” is illuminated when the output is activated and is reset via the front panel reset control.
The output can also be disabled by using the front panel controls. Once disabled the relay will
remain off until re-enabled and the front panel indicator “Fire Output Disabled” is illuminated.
5.4.2 Fault Output Relay
The Fault Output Relay is energised if the FACP is operating normally and has unsupervised 1A
30VDC voltage free single change over contacts. The output can be disabled by using the front
panel control. Once disabled the relay will remain on until it is re-enabled and the FAULT OUTPUT
front panel indicator is illuminated when this output is disabled.
If a fault is present on the FACP the output relay is de-energised and remains de-energised until the
fault conditions have cleared. There are a number of front panel fault indicators that detail the nature
of the fault. These are:
Power Fault – fault relating to the power supply.
System Fault – fault relating to the operation of the FACP.
Auxiliary Power Fault – fault relating to the auxiliary power output.
Individual zone fault indicators.

Note:
All faults are non latching, except for system fault.
Note:
Faults associated with zones are cleared on a reset condition.
