Terminal

Function/Description

Legend

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 AL175ULX 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 AL175ULXs with fire alarm tie-in
(Fig. 5 and Fig. 6, 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. 4, pg. 4).

+ BAT --

Stand-by battery connections.

AC FAIL

Used to notify loss of AC e.g connect audible device or alarm panel relay normally energized

N.C., C, N.O.
