Installation Instructions:

The AL1024ULXB should be installed in accordance with article 760 of The National Electrical Code as well as
NFPA 72 and all applicable Local Codes.
1. Mount the AL1024ULXB in desired location/enclosure.
2. Connect unswitched AC power (115VAC 60Hz to terminals marked [L, G, N] (Fig. 1). Use 14 AWG or larger

for all power connections (Battery, AC input, DC output). 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). DC output Minimum .25” spacing must be provided.

3. Connect devices to be powered to terminals marked [-- DC +] (Fig. 1).
4. Measure output voltage before connecting devices. This helps avoid potential damage.
5. 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
battery to terminals marked [+ BAT -] (Fig. 1).

6. It is required to connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 1) supervisory

relay outputs. Use 22AWG to 18AWG wires. AC FAIL will report in 5 minutes.
To delay report 6 hours cut “AC delay” jumper.
