MOM5 Sub-Assembly - 1 -

Overview:

The MOM5 is a UL Listed Sub-Assembly multi-output power distribution module that converts one (1) non power-limited

DC voltage input to five (5) power-limited outputs. Each output will route power to a variety of access control hardware

and devices which includes Mag Locks, Electric Strikes, Magnetic Door Holders, etc. These outputs will operate in both

Fail-Safe and Fail-Secure modes. Controlled trigger input is achieved through normally open [NO] or normally closed [NC]

supervised input or the polarity reversal from an FACP (Fire Alarm Control Panel). A form “C” dry output relay will enable

HVAC Shutdown, Elevator Recall or trigger auxiliary devices.

Installation Instructions:

Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, The Canadian Electrical

Code, Part 1 and with all local codes and authorities having jurisdiction. Product is intended for indoor use only.

1. Refer to Sub Assembly Installation Instructions for mounting Rev. MS050913.

2. Connect the DC output of the UL Listed power supply to the terminals marked [- DC input +]

carefully observing polarity.

3. Connect door strikes (Fail-Secure) positive to terminals marked [1 through 5 Pos. (+) DC Output (Alarm)]

and negative to [NEG. 1 through NEG. 5].

4. Connect door holders (fail-safe) positive to terminals marked [6 through 10 Pos. (+) DC Output (Stand-by)]

and negative to [NEG. 1 through NEG. 5].

5. To trigger the MOM5 from a FACP connect signaling circuit of FACP to inputs marked [NEG. (-)]

and [POS. (+)] input. Polarity is shown in alarm condition. Put wires coming to

each terminal on different sides of the screw.

6. To trigger the MOM5 using a supervised dry contact connect the 2.2K resistor in series for a

[NC] trigger input and in parallel for N.O. trigger input.

7. Connect the auxiliary devices that are to be triggered by the MOM5 to the terminals marked

[NO & C] for normally open outputs and terminals marked [NC & C] for normally closed output.

8. This relay will energize when the MOM5 is triggered.

9. Connect trouble reporting device to the terminals marked [Power Fail]. Connect to the [NO & C] for

normally open and [NC & C] for normally closed output.

10. This relay will switch when power is lost to the MOM5.

Note: This product is a UL Listed Sub-Assembly for use with Altronix UL Listed power supplies as indicated

in the installation manuals for the power supply.
