Fire Protective Signaling Systems (UL 1481).
Input:
• Input 115VAC / 60Hz, 4.2 amp.
Output:
• 24VDC output (UL 1481).
• 8 amp continuous supply current with 10 amp
supply current during alarm.
• 24VDC @ 10 amp. (UL 294).
• Filtered and electronically regulated output.
• Maximum Ripple: 250mV P/P
Battery Backup:
• Built-in charger for sealed lead acid or gel type batteries.

The AL1024ULXB2 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 AL1024ULXB2 in the desired location/enclosure.
2. Connect unswitched AC power (115VAC 60Hz) to the terminals marked [L, N] (Fig. 1, pg. 2). 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 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. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect devices to be powered to the terminals marked [+ DC -- ] (Fig. 1, pg. 2).
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, pg. 2).
6. It is required to connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 1, pg. 2)
supervisory relay outputs. Use 22AWG to 18AWG wires. AC FAIL will report in 5 minutes.
To delay report for 6 hours cut "AC Delay" jumper (Fig. 1a, pg. 2).
