How to Use the Assembly/Model

Application

The Model 12579-003 Monitored Relay Module (MRM) is a Snaptrack module designed for use in the

SmartSeries systems. GAI-Tronics uses the MRM to provide a maximum of eight independently

controlled relay-contact outputs. Each of the eight relay-contact outputs has an associated LED to

indicate its current status. These relay-contact outputs are typically used to switch power to signaling

devices, such as beacons, on command from the 69254 Series or 69440 Series Master Control Unit

(MCU).

The MRM also provides the capability of supervising the cable runs to these signaling devices for such

abnormal conditions as open-circuit conditions, ground faults, and wire-to-wire short circuit conditions.

In addition, if fewer than eight relay-contact outputs are needed for a particular application, then the

MRM may also be used to receive inputs from field devices. The MRM is comprised of three main

components: the 69613-001Central Processing Unit (CPU) printed circuit board assembly (PCBA), the

69252-001 Power Relay Module, and the 69251-201 Monitored-In-8 PCBA.

The MRM is designed to be mounted in a Snaptrack that is installed in an enclosure. Snaptrack is a

grooved plastic channel designed to allow PCBAs to securely ‘snap’ into the groove. The Snaptrack

provides flexible installation because the track may be installed inside an enclosure wherever it is

convenient.

The MRM communicates with the MCU via the 69613-001 CPU PCBA over a FSK modem intended for

use in GAI-Tronics SmartSeries systems. This FSK link (page line) is periodically monitored by the

MCU for any interruptions in communication. The MCU uses this communication channel to control

activation/de-activation of the MRM’s relay-contact outputs. In turn, the MRM uses this communication

channel to report to the MCU any cable run fault conditions that are detected. The MCU identifies a

particular MRM on this FSK link by its module address. This module address is set by rotary hex switch

S1 and S2 of the MRM (located on the CPU PCBA.) The range of valid settings is from 05 to FE (hex).
