Spec Sheet

Installation Instructions:
The unit should be installed in accordance with The National Electrical Code, as well as NFPA 72 and all applicable
Local Regulations.
1. Mount the unit in desired location. 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 (pgs. 3 & 4) Terminal Identification Table (pg. 7)
LED Diagnostics (pg. 6) Typical Application Diagrams (pgs. 8 & 9)
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. AL1012ULM is 12VDC only and AL1024ULM is 24VDC only.
(Output Voltage and Stand-by Specification Charts below and 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).
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
(Fig. 1, pg. 5) and the negative leads to
terminals marked [NEG 1 through NEG 5] on MOM5 board
(Fig. 1, pg. 5).
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
(Fig. 1, pg. 5) and negative leads to
terminals marked [NEG 1 through NEG 5] on MOM5 board
(Fig. 1, pg. 5).
7. To trigger the unit from a FACP connect signaling circuit of FACP to terminals marked [- INPUT +] on MOM5
board
(Fig. 1, pg. 5). Polarity is shown in alarm condition. For latching fire alarm interface
(Fig. 5, 6, 7, pg. 9).
Note: A 2.2K EOL must be installed across ter
minals mark
ed [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 N.C. trigger input
and in parallel for N
.O
. trigger input
(F
ig
. 2, pg. 8).
9. Connect auxiliary devices triggered by the unit to the terminals marked [DRY OUTPUT N.O. & C] on MOM5 board
for normally open output or terminals marked [DRY OUTPUT N.C. & C] on MOM5 board for normally closed
output
(Fig. 1, pg. 5).
Note: This relay will energize when the unit is triggered.
10.
F
or Access Control applications batteries are optional. When batteries are not used a loss of AC will result in the loss
of output v
oltage. Batteries must be lead acid or gel type if used. Connect one (1) 12VDC batter
y to ter
minals
marked [+ BAT -- ] on power supply board
(Fig. 1, pg. 5) for 12VDC operation. Use two (2) 12VDC batteries
connected in series for 24VDC operation. (Battery leads included).
11. Connect supervisory trouble reporting devices to outputs marked [AC FAIL, LOW BAT]
(Fig. 1A, pg. 5) and
[Power Fail]
(Fig. 1, pg. 5) supervisory relay outputs marked [N.O., C, N.C.] on power supply board. Use 22 AWG
to 18 AWG for AC Fail & Low Battery reporting.
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.
12. Please insure that the co
ver is secured with the provided Key Lock.
