This installation manual contains sensitive business and technical information that is confidential and
proprietary to GAI-Tronics. GAI-Tronics retains all intellectual property and other rights in or to the

General Information
The Model 379-003 IP MRM (Monitored Relay Module) station operates in a GAI-Tronics IP paging and
alarm system. The IP controller’s software configuration controls its operation.
The MRM includes eight relay output circuits. Each relay contains two type C contacts rated for 5 amps.
Relay outputs typically switch power to signaling devices such as beacons or strobes but are applicable to
any switching application that does not exceed the relay’s current rating. Relay circuits are programmable
to activate during:
•system alarms
•pages
•trouble conditions
The MRM also includes eight input circuits (one for each output relay). Input circuits normally supervise
the relay output circuit cable to the signaling device (as described above). Monitoring for open circuits,
short circuits, and ground fault conditions occurs while the output circuit is inactive. The relay circuit will
not activate while a cable fault is present, preventing a possible dangerous condition.
Use relay inputs not supervising an output circuit for other functions. A voltage-free contact (opening or
closing) or the presence/absence of a 24 V dc input voltage activates each input. The IP MRM can
supervise the cabling between the input terminal and the remote contact device when using voltage-free
input contacts. The IP MRM can monitor the cable for open circuit, short circuit, and ground fault
conditions and automatically reports fault conditions to the system controller.
Program each input circuit to initiate one of the following functions in the GAI-Tronics IP paging and
alarm system:
•activate an alarm
•reset all alarms
•cancel the current alarm
•report a fault condition
•reset the system MCU

The Model 379-003 IP MRM station’s housing is a NEMA 4X stainless steel enclosure measuring 13.00
W × 14.30 H × 6.23 D inches (330.2 × 363.2 × 158.2 mm) (see Figure 1). Internal components include:
• 24 V dc power supply
• No. 030-02-0099-008 Monitored Relay Module
The No. 030-02-0099-008 IP MRM has four components (see Figure 1):
• No. 999-02-1203-001 CPU PCBA
• No. 999-02-3011-002 Monitored-Input PCBA
• Two—No. 999-02-3002-001 Relay PCBAs.
The scope of this manual is mounting and wiring the Model 379-003 IP MRM station. Refer to Pub. 502-
20-0672-001 ISS 4 for additional information on the No. 030-02-0099-008 IP MRM (see the Reference
Documentation section).

Installation
CAUTION —Do not install this equipment in hazardous areas. Disconnect power before
installing or removing the MRM.
Mounting
Mount the Model 379-003 IP MRM station vertically (see Figure 2). Select a mounting location that is
flat, provides proper clearance, and is rigid and strong enough to support the enclosure. The IP MRM
station weighs 19 pounds (8.6 kg)
1. Mount the enclosure using ¼-20 (M6) hardware, appropriate for the mounting surface, through the
four 0.31-inch (7.9 mm) diameter holes, on the mounting flanges (see Figure 2).
• Determine the mounting hardware length by the thickness of the mounting surface or by the
anchoring method the customer selects.
NOTE: Due to the various surface types the station mounts to, the customer must supply the
mounting hardware.
• The suggested height of the station is 48 inches (1219 mm) to the center of the enclosure’s
bottom mounting holes.
• GAI-Tronics supplies the Model 379-003 IP MRM station enclosure with two 1-1/4-inch holes
and one ¾-inch hole with sealing hole plugs (see Figure 3). Remove hole plugs and install
(customer supplied) liquid tight conduit or cable glands when connecting field wiring.
• Use entry hole A for ac input power wiring. Use entry holes B and C for signal/control and/or
Ethernet connections (see Figure 3).
2. Remove the shipping tie-wrap securing the PCBA to the mounting Snaptrack.

Wiring
The IP MRM station requires 120 to 230 V ac, 50/60 Hz power and an Ethernet connection to an IP
system controller. Connect the eight relay outputs and input contact circuits as needed. Refer to Pub. 502-
20-0672-001 ISS 4 for detailed information on I/O circuits, I/O circuit connections, and I/O configuration
(see the Reference Documentation section).
Power
Connect 120 to 230 V ac power to terminal block TB22, at the top of the panel (see Figure 1). Use 14
AWG (2.5 mm2) minimum power conductors and an all-pole main switch (circuit breaker).
WARNING —Ensure proper grounding to protective earthing.
The grounding stud, next to terminal block TB22 (see Figure 1) provides the earth ground termination.
Minimum wire gauge is 14 AWG.
