The AL176UL is a power-limited power supply/charger that converts a 115VAC / 60Hz input into 12VDC or 24VDC

output (see specifications). It is intended for use in applications requiring UL Listing for Access Control (UL294). It must

be installed in accordance with National and Local Electrical Codes and Regulations.

Agency Listings:

• UL Listed - U.S. and Canada for

Access Control Systems (UL294).

Input:

• Input 115VAC/60Hz, 0.6A.

Output:

• Field selectable 12VDC or 24VDC output.

• 1.75A supply current.

• Class 2 Rated power-limited output.

• PTC protected outputs, rated @ 2.5A.

• Filtered and electronically regulated output.

• Short circuit and thermal overload protection.

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. 2 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. 4).

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, AC input). Use 22 AWG to 18 AWG for power-limited

circuits (DC output, AC FAIL and LOW BAT supervisory relays).

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 AL176UL to the desired DC output voltage by either removing/leaving jumper.

(see Power Supply Output Specifications).

Note: Measure output voltage before connecting devices. This helps avoiding potential damage.
