- All models are available in red enclosure (add an “R” suffix to the part #, e. g. AL1024ULXPD8R).
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.
- 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 three 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. 8). Secure enclosure to earth ground.
- Connect AC power (115VAC, 60 Hz) to the terminals marked [L, N] (Fig. 1, pg. 5). 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 14 AWG or larger for all power connections (Battery, DC output, AC input). Use 22 AWG to 18 AWG for power-limited circuits (AC Fail/Low Battery reporting). 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. For Fire Alarm applications the outputs are “Special Applications” only, see list (refer to Appendix A, pg. 6). For other devices contact Underwriters Laboratories to ensure compatibility. - Measure output voltage before connecting device. This helps avoiding potential damage. When servicing the unit AC mains should be removed.
- Connect devices to be powered:
- a. For AL1024ULX Power Supply: connect devices to the terminals marked [+ DC –] (Fig. 1, pg. 5)
- . For other Power Distribution Models: connect devices to be powered to terminal pairs 1 to 4 marked[1P & 1N] through [4P & 4N] (Fig. 2a & 2b, pg. 7) or 1 to 8 marked [1P & 1N] through [8P & 8N] (Fig. 3a & 3b, pg. 7), carefully observing correct polarity.
- 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.
- Connect appropriate signaling notification devices to the terminals marked [AC FAIL & BAT FAIL]
(Fig. 1, pg. 5) supervisory relay outputs.
Note: When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay must be used to provide a visual indication of AC power on. - Please ensure that the cover is secured with the provided Key Lock.
CAUTION: De-energize unit prior to servicing. For continued protection against risk of electric shock and fire hazard replace fuse with the same type and rating. Do not expose to rain or moisture.
CAUTION: Optional rechargeable stand-by batteries must match the power supply output voltage setting. Keep power-limited wiring separate from non power-limited. Use minimum 0.25″ spacing.
Wiring:
Use 14 AWG or larger for all power connections.
Note: Take care to keep power-limited circuits separate from non power-limited wiring (115VAC, Battery).
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. 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 discharges is 3.6A.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
