Terminal Identification - Altronix AL175ULX Installation Instructions

Terminal Legend Function/Description
These input terminals are designed to connect to the normally closed outputs of an access control or
TRG1 and TRG2 fire alarm relay. These terminals control [LOCK+], and [STRIKE+], as well as AL175ULX output
relay contacts [NC, NO, C]
This terminal provides DC output voltage when [TRG1] and [TRG2] are shorted together and are
LOCK+
typically used to power Mag Locks.
This terminal provides DC output voltage when [TRG1] and [TRG2] are unshorted and are typically
STRIKE+
used to power Electric Strikes.
Isolated dry Form "C" contacts. Shorting [TRG1] and [TRG2] together causes these contacts to
NC, NO, C 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 Indicates loss of AC e.g connect audible device or alarm panel relay normally energized
NC, C, NO When AC power is present. Contact rating 1A @ 28VDC.
