MOM5C - 1-

Overview:

The MOM5C multi output power distribution module 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:

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 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, pg. 4).

Connect the DC of the power supply to the terminals marked [--DC Input +] carefully observing polarity.

3. Connect door strikes (fail-secure) positive to terminals marked [1 thru 5 Pos. (+) DC Output (Alarm)]

and negative to [NEG1] thru [NEG5] (fig. 7, pg

. 4).

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

and negative to [NEG1] thru [NEG5] (fig. 7, pg. 4).

To trigger the MOM5C from a FACP connect signaling circuit of FACP to terminals marked [- INPUT +].

Polarity is shown in alarm condition. Connect the wires on opposite sides of the screw.

6. To trigger the MOM5C using a supervised dry contact connect a 2.2K resistor in series to terminals marked

[TRIGGER] for a NC (Normally Closed) trigger input or connect a 2.2K resistor in parallel to terminals marked

[TRIGGER] for NO (Normally Open) trigger input (fig. 7, pg. 4).

Connect the auxiliary devices that are to be triggered by the MOM5 to terminals marked [Dry Output]:

For Normally Open operation connect wires to the terminals marked [NO & C].

For Normally Closed operation connect wires to the terminals marked [NC & C].

Note: This relay will energize when the MOM5C is triggered.

Connect trouble reporting device to the terminals marked [Power Fail].

For Normally Open operation connect wires to the terminals marked [NO & C].

For Normally Closed operation connect wires to the terminals marked [NC & C].

Note: This relay will switch when power is lost to the MOM5C.
