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 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 the 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. 13,14).
Secure enclosure to earth ground. It is recommended to first review the following tables for screw
terminals, switch selection and LED status indications. This will greatly facilitate installation hook-up.
Carefully review:
Output Voltage & Stand-by Specifications

(pg. 10)
LED Diagnostics
(pg. 9)
Typical Application Diagrams (pgs. 11 & 12)
2. Set output voltage:
AL300ULM, AL400ULM and AL600ULM set desired DC output voltage by setting switch SW1 to the appropriate
position on the power supply board (Fig. 1B, pg. 5; Fig. 2B, pg. 6). AL1012ULM is 12VDC only and AL1024ULM
is 24VDC only. (Output Voltage and Stand-by Specification Charts below, pg. 4).
3. Secure green lead to earth ground. Connect AC power (115VAC 60Hz to terminals marked [L, G, N] on
power supply board (Fig. 1, pg. 5; Fig. 2, pg. 6; Fig. 3, pg. 7; Fig. 4, pg. 8).
Use 18 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).
4. Measure output voltage before connecting devices. This helps avoid potential damage.
Keep power limited wiring separate from non-power limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum .25” spacing must be provided.
5. Connect Fail-Secure type locking hardware (e.g. door strikes and electronic dead bolts) positive leads to terminals
marked [1 through 5 POS (+) DC OUTPUT (ALARM)] on MOM5 board and the negative leads to terminals marked
[NEG 1 through NEG 5] on MOM5 board (Fig. 1, pg. 5; Fig. 2, pg. 6; Fig. 3, pg. 7; Fig. 4, pg. 8).
6. Connect Fail-Safe type locking hardware (e.g. mag locks, door strikes and door holders) positive leads to terminals
marked [6 through 10 POS (+) DC OUTPUT (STAND-BY)] on MOM5 board and negative leads to terminals
marked [NEG 1 through NEG 5] on MOM5 board (Fig. 1, pg. 5; Fig. 2, pg. 6; Fig. 3, pg. 7; Fig. 4, pg. 8).
7. To trigger the unit from a FACP connect signaling circuit of FACP to terminals marked [- INPUT +] on MOM5
board (Fig. 1, pg. 5; Fig. 2, pg. 6; Fig. 3, pg. 7; Fig. 4, pg. 8). Polarity is shown in alarm condition. For latching
fire alarm interface (Figs. 8, 9, 10, pg. 12).
Note: A 2.2K EOL must be installed across terminals marked [TRIGGER] on MOM5 board or the unit will remain
in an alarm condition.
8. To trigger the unit using a supervised dry contact connect the 2.2K resistor in series for a NC trigger input
and in parallel for [NO] trigger input (Fig. 5, pg. 11).
9. Connect auxiliary devices triggered by the unit to the terminals marked [DRY OUTPUT NO & C] on MOM5 board
for normally open output or terminals marked [DRY OUTPUT NC & C] on MOM5 board for normally closed
output (Fig. 1, pg. 5; Fig. 2, pg. 6; Fig. 3, pg. 7; Fig. 4, pg. 8).
Note: This relay will energize when the unit is triggered.
10.For Access Control applications batteries are optional. When batteries are not used a loss of AC will result in the loss
of output voltage. Batteries must be lead acid or gel type if used. Connect one (1) 12VDC battery to terminals
marked [+ BAT -- ] on power supply board for 12VDC operation (Fig. 1, pg. 5; Fig. 2, pg. 6; Fig. 3, pg. 7;
Fig. 4, pg. 8). Use two (2) 12VDC batteries connected in series for 24VDC operation. (Battery leads included).
Visual Indicators:
• DC output LED indicator.
• LEDs indicate condition of power outputs.
• Power & input trigger LED’s.
Supervision:
• AC fail supervision (form "C" contact).
• Low battery supervision (form "C" contact).
Supervision (cont’d):
• Battery presence supervision (form “C” contact).
• Power fail supervision relay (form “C” contact rated
1 amp @ 28VDC).
• Power supply is complete with enclosure, cam lock,
transformer and battery leads.
