Power Supply Output Specifications:

Output VDC| Jumper| Max. Stand-by Load DC| Max. Alarm Load DC| Battery (optional)
---|---|---|---|---
12VDC| Jumper Removed| 1.75A| 1.75A| 12VDC
24VDC| Jumper On| 1.75A| 1.75A| 24VDC

Stand-by Specifications:

24VDC / 7 AH Battery

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. 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

2. Connect AC power to the black and white flying leads of the transformer. Secure green wire lead to earth ground. Green “AC” LED on power supply board will turn on. This light can be seen through the LED lens on the door of the enclosure. 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 AL176ULX to the desired DC output voltage by either removing/leaving jumper.
   Note: Measure output voltage before connecting devices. This helps avoiding potential damage.

4. Connect battery to the terminals marked [+ BAT –] on the unit (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 in the loss of output voltage.
   When the use of stand-by batteries is desired, they must be lead acid or gel type.

5. Connect appropriate signaling notification devices to AC Fail and Low Bat 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.

6. For Access Control Device connections refer to Terminal Identification Chart.

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 (Power Supply Output Specifications Chart).

• Battery Test:
  Under normal load conditions check that the battery is fully charged, check specified voltage both at the 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 discharge is 400mA.
  • Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.

LED Diagnostics:

Terminal Identification:

(–) output (ground).
+ BAT –| Stand-by battery connections.
AC FAIL NO, C, NC| Used to notify loss of AC, e.g. connect audible device or alarm panel.
Relay is normally energized when AC power is present. Contact rating 1A @ 28VDC.
LOW BAT NO, C, NC| Used to notify low battery condition, e.g. connect audible device or alarm panel. Relay is normally energized. Contact rating 1A @ 28VDC.
