Terminal Identification:
Terminal Legend Function/Description
XFMR
Low voltage transformer connections.
+ AUX –
Aux. power output terminals. These terminals supply 12VDC or 24VDC not affected by trig-
ger, reset or fire alarm interface.
LOCK +
COM –
Switched power output. Fail-Safe [LOCK +] supplies positive power when unit is not trig-
gered and FACP interface is inactive. Fail-Secure [] supplies positive power when
unit is triggered and/or fire alarm interface is activated.
[COM –] supplies negative power.
FACP1
FACP2
Supervised by 2.2K end of line resistor FACP interface. Short or open will cause power to
be dropped to terminal marked [LOCK +] and supply power to terminal marked [].
Condition can be maintained even after restoration of the circuit (latching mode).
TRG INPUT
NO, GND
Short between these two terminals will cause power to be dropped to the terminal marked
[LOCK+] and supplied to the terminal marked [].
RESET
NO, GND
Momentary short between these terminals would end latching FACP interface condition.
Feature active only if latching FACP is selected (SW1 ON).
+ BAT –
Stand-by battery connections.
LED Diagnostics:
Red
Power Supply Status
ON
Normal function.
OFF
No DC output.
Slow Blink
Loss of AC.
Rapid Blink
Unit is triggered, awaiting reset. Fire alarm interface activated.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user
to the presence of an insulated DANGEROUS VOLTAGE within the product’s enclosure that may be of
sufficient magnitude to constitute an electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of impor-
tant operating and maintenance (servicing) instructions in the literature accompanying the appliance.
CAUTION:
To reduce the risk of electric shock do not open
enclosure. There are no user serviceable parts inside. Refer servicing
to qualified service personnel.
