TRG1 & TRG2
These input terminals are designed to connect to the normally closed
outputs of an access control or fire alarm relay. These terminals control [LOCK+],
and [STRIKE+], as well as AL175ULX2 output relay contacts [N.C., N.O., C]
LOCK+
This terminal provides DC output voltage when [TRG1] and [TRG2] are shorted
together and are typically used to power Mag Locks.
STRIKE+
This terminal provides DC output voltage when [TRG1] and [TRG2] are unshorted
and are typically used to power Electric Strikes.
N.C., N.O., C
Isolated dry Form “C” contacts. Shorting [TRG1] and [TRG2] together causes
these contacts to switch. They are typically used for controlling multiple
AL175ULX2s with fire alarm tie-in (Fig. 4, pg. 4).
AUX +
Continuous positive (+) DC power output voltage.
It is not affected by TRG1, TRG2 operation.
COM -
Common negative (-) output (ground).
FACP
Spare wiring terminal used for fire alarm tie-in application (Fig. 3, pg. 4).
BAT+, BAT-
