- 4 - M Series
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 (Figs. 1 - 4, pgs. 6 - 9).
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 (Figs. 1 - 4, pgs. 6 - 9).
7. To trigger the unit from a FACP connect signaling circuit of FACP to terminals marked [– INPUT +] on
MOM5 board (Figs. 1 - 4, pgs. 6 - 9). Polarity is shown in alarm condition.
For latching fire alarm interface see Fig. 7, pg. 11; Figs. 8 & 9, 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 (Figs. 1 - 4, pgs. 6 - 9).
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 (Figs. 1 - 4, pgs. 6 - 9).
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] and [Power Fail]
supervisory relay outputs marked [NO, C, NC] on power supply board (Figs. 1a - 4a, pgs. 6 - 9).
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 should be
utilized to visually indicate that AC power is on.
To delay report for 6 hours cut “AC Delay” jumper (Figs. 1b - 4b, pgs. 6 - 9).
12. Please ensure that the cover is secured with the provided Key Lock.
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions the DC output voltage should be checked for proper
voltage level (Output Voltage and Stand-by Specification Charts, pg. 4).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage at
the battery terminals and at the board terminals marked [– BAT +] to ensure that there is no break in the battery
connection wires.
Note: AL300ULXB2, AL400ULXB2, AL600ULXB and AL1012ULXB (Power Supply Board) maximum
charge current is 0.7A.
AL1024ULXB2 (Power Supply Board) maximum charge current is 3.6A.
Expected battery life is 5 years; however, it is recommended to change batteries within 4 years or less if necessary.
