AL175ULX - 1 -

Overview:

The AL175ULX is a power-limited power supply/charger that will convert 115VAC / 60Hz input into two individually

PTC protected 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 power-

limited 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.

Terminal Identification: Terminal Legend Function/Description These input terminals are designed to connect to the normally closed outputs of an access control or TRG1 & 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.
