Installation Instructions:

The AL176ULX should be installed in accordance with article 760 of The National Electrical Code or NFPA 72 as well
as all applicable Local Codes.
See Terminal Identification Chart on page 3 for a description of each terminal function.
1. Mount the AL176ULX in desired location.
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 .25” spacing must be provided.

3. Set the AL176ULX to the desired DC output voltage by either removing/leaving jumper.

(Power Supply Output Specification Table).
Note: It is important to measure output voltage before connecting devices. this helps avoid potential damage.

4. Connect battery to terminals marked [+ BAT -] on the power supply board (battery leads included). Use two (2)

12VDC batteries connected in series for 24VDC operation.

Note: For Access Control applications, batteries are optional. When batteries are not used a loss of AC will result
