AL175ULX
Access Control Power Supply/Charger
Overview:
The AL175ULX is a power-limited power supply/charger that will convert 115VAC / 60Hz input into two individually PTC
protected auto-resettable 12VDC or 24VDC outputs (see specifications). It is intended for use in applications requiring UL
Listing for Access Control System Units (UL 294) and applications requiring an interface with the Fire Alarm Control Panels.

Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all local codes and authorities having jurisdiction. Product is intended for indoor use only. See Terminal Identification Chart on Pg. 3 for a description of each terminal function.
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the
enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s
upper keyholes over the two upper screws; level and secure. Mark the position of the lower two holes. Remove the
enclosure. Drill the lower holes and install two fasteners. Place the enclosure’s upper keyholes over the two upper
screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 3).
Secure enclosure to earth ground.
2. Connect AC power to the black and white flying leads of the transformer. Secure green wire lead to earth ground.
Use 18 AWG or larger for all power connections (Battery, DC output). Use 22 AWG to 18 AWG for powerlimited circuits (trigger inputs, dry outputs).
Keep power-limited wiring separate from non power-limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum 0.25” spacing must be provided.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
3. Set the AL175ULX to the desired DC output voltage by setting switch SW1 to the appropriate position (refer to
Power Supply Output Specification Table).
4. Measure output voltage before connecting devices. This helps avoiding potential damage.

5. Connect one (1) 12VDC battery to the terminals marked [+ BAT -- ] (Fig. 1, pg. 2) for 12VDC operation. Use two
(2) 12VDC batteries connected in series for 24VDC operation (Battery leads included).
Note: For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the
loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type. Use two
(2) 12VDC batteries connected in series for 24VDC operation.
6. Connect appropriate signaling notification devices to AC Fail supervisory relay outputs.
Note: To meet UL requirements, AC Supervisory outputs must be connected to the zone of Alarm Control Panel
or to visual AC trouble indicator.
7. For Access Control Device & Fire Alarm Interface connections refer to desired Application Diagrams (pg. 4)
and Terminal Identification Chart (pg. 3).
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level (refer to Power Supply Output Specifications Chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at battery terminal and at the board terminals marked [- BAT +] to ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharges is 0.40A.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.

Terminal Identification:
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.
