Terminal Legend Function/Description
XFMR Low voltage transformer connections.
Aux. power output terminals. These terminals supply 12VDC or 24VDC not affected by trig-
+ AUX –
ger, reset or fire alarm interface.
Switched power output. Fail-Safe [LOCK +] supplies positive power when unit is not trig-
LOCK +
gered and FACP interface is inactive. Fail-Secure [STRIKE +] supplies positive power when
STRIKE +
unit is triggered and/or fire alarm interface is activated.
COM –
[COM –] supplies negative power.
Supervised by 2.2K end of line resistor FACP interface. Short or open will cause power to
FACP1
be dropped to terminal marked [LOCK +] and supply power to terminal marked [STRIKE +].
FACP2
Condition can be maintained even after restoration of the circuit (latching mode).
TRG INPUT Short between these two terminals will cause power to be dropped to the terminal marked
NO, GND [LOCK+] and supplied to the terminal marked [STRIKE +].
RESET Momentary short between these terminals would end latching FACP interface condition.
NO, GND Feature active only if latching FACP is selected (SW1 ON).
+ BAT – Stand-by battery connections.
