AL300ULX Series
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.
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
(Enclosure Dimensions, pgs. 7, 8)
. Secure enclosure to earth ground.
2. Set the unit to the desired DC output voltage by setting SW1
(Fig. 1c, pg. 3)
to the appropriate position
(Power Supply Output Specification Chart, pg. 2).
3. Secure cabinet to earth ground. Connect AC power (115VAC, 60Hz to the terminals marked [L, N]
(Fig. 1, pg. 3)
. 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.
4. Measure output voltage before connecting device. This helps avoiding potential damage.
When servicing the unit, AC mains should be removed.
5. Connect devices to be powered:
a. For AL300ULX Power Supply: connect devices to the terminals marked [+ DC –]
(Fig. 1, pg. 3)
.
b. For other Power Distribution Models: connect devices to be powered to the terminal pairs 1 to 4 marked
[1P & 1N] through [4P & 4N]
(Fig. 2a & 2b, pg. 5)
or 1 to 8 marked [1P & 1N] through [8P & 8N]
(Fig. 3a & 3b, pg. 5),
carefully observing correct polarity.
6. 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 one (1) 12VDC battery to the terminals marked [+ BAT –] for 12VDC operation.
Use two (2) 12VDC batteries wired in series for 24VDC operation.
7. Connect appropriate signaling notification devices to AC FAIL & BAT FAIL
(Fig. 1a, pg. 3)
supervisory
relay outputs.
Note:
When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay should be
utilized to visually indicate that AC power is on. To delay report for 6 hours cut “AC Delay” jumper
(Fig. 1b, pg. 3)
.
8. Please ensure that the cover is secured with the provided key lock.
