1.7 System Components
Basic System
A basic system consists of the Back Box, Main Board,
Display Board and one transformer. Canadian versions also include an Eight Zone LED Module.
Back Box
The enclosure includes the back box, outer door, dead front door and hardware plate. It can be flush or surface mounted without requiring additional hardware.
Both the outer door and dead front doors are quickly removable using pin-hinges. The hardware plate holds the main printed circuit board and transformer(s). The enclosure holds two transformers, one communicator module (Dialer or City Connect) and up to three NAC or
Relay expander modules.
Transformer
The FACP is shipped with either a 120V or 240V transformer (specified at the time of ordering).
The total NAC power can be increased by adding a second transformer of the same voltage. The expansion transformer is available as a separate order item under model numbers MR12VAC (for 120V systems) and MR24VAC (for 240V systems).

Main Board
The MR-2100 / MR-2200 Main Board contains the system power supply, master CPU and memory, two
Notification Appliance Circuits (NACs), four Auxiliary
Function Relays, two Auxiliary power points, one or two
Signal Line Circuits (SLCs), and communications ports for the Display Board and optional equipment.
The MR-2100 Main Board has one SLC for connecting
System Sensor Addressable devices. The MR-2200
Main Board has two SLCs. Each SLC can support 198 total devices, 99 detectors/sensors and 99 control/ monitor type devices.
Replacement Main Boards are available under the following PIDs:
MR-2100 Main Board – SMR21MPCB
MR-2200 Main Board – SMR22MPCB

Display Board
The Display Board provides LED and LCD status annunciation, hotkeys, and keypads for message retrieval and programming. A replacement Display can be ordered under PID SMR22DPCB.
Optional (Internal) Components
NAC Expander Board - PID MRNC2
The NAC Expander Board provides two additional NAC output circuits. A ribbon cable connects this module.
Any combination of NAC and Relay expanders can be added (to a maximum of three modules total) within the basic enclosure.
Refer to the MRNC2 NAC Expander Installation
Instructions (579-499).
Relay Expander - PID MRRL4
The Relay Expander provides four additional function relay output circuits. A ribbon cable connects this module. Any combination of NAC and Relay expanders can be added (to a maximum of three modules total) within the basic enclosure.
Refer to MRRL4 Relay Expander Installation instructions (579-500).
Eight Zone LED Module - PID MRLD8
The MRLD8 module provides eight zones of LED annunciation. The LED strips mount to the dead-front door and connect to the MR-2244 display board. Up to three of these modules can be added to the MR-2244.
Refer to the MRLD8 Eight Zone Expansion Module
(579-498).
4
DACT Module - PID MRDL
The optional Digital Alarm Communicator Transmitter
(DACT) module is added to the system to provide
Remote Station monitoring of system alarm, trouble, and supervisory conditions.
Use of the DACT module requires that two telephone lines be provided for connection to the DACT. Service must be arranged with a Central Station monitoring facility for Remote Station Service.
Refer to the MRDL Installation Instructions (579-573).
MRDL not to be used for ULC applications.
MR22NTWR
The MR22NTW provides the network interface between the MR-2200 and the rest of the control units on a peer-to-peer network. This module plugs directly into the MR-2200 main board.
There are four distinct versions of this network interface module. For information on wiring each assembly refer to the MR22NTW Network Card Installation Instructions
(579-541). Secutron Network cards meet requirements for UL864 only.
The MR22NTWR version features two standard ports that provide direct wire connectivity between multiple
FACPs. The MR22NTWR can also be used for creating a Fiber-Optic connection between panels using two
MR-D1010 Fiber Optic Modules.
MR22NTWR1
The MR22NTWR1 provides the network interface between the MR-2200 and the rest of the control units on a peer-to-peer network. This module plugs directly into the MR-2200 main board.
The MR22NTWR1 version features Port 1 as RS232 and Port 2 as standard, RS-232 serial ports are used for connecting the MR-D1010 Fiber Optic Module.
MR22NTWR2
The MR22NTWR2 provides the network interface between the MR-2200 and the rest of the control units on a peer-to-peer network. This module plugs directly into the MR-2200 main board.
The MR22NTWR2 version features Port 1 as standard and Port 2 as RS232.

MR22NTWR12
The MR22NTWR12 provides the network interface between the MR-2200 and the rest of the control units on a peer-to-peer network. This module plugs directly into the MR-2200 main board.
The MR22NTWR12 version features Port 1 and Port as both RS232.
Reverse Polarity Municipal Box - PID MRCTYB
The optional MRCTYB can be configured for remote
Station (reverse polarity) or Municipal Master (local energy) service. The MRCTYB can transmit alarm, trouble, and supervisory conditions when configured for reverse polarity operation. Alarm condition only is reported when configured for Municipal Master operation.
Refer to the MRCTYB Reverse Polarity Municipal Box
(RPMB) Module Installation Instructions (579-538).

Testing Circuit Supervision
Use the following procedures in the table below to confirm that SLCs and NACs are supervising for opens, shorts, and grounds. The right column in this table shows the LEDs that illuminate when an open, short, or ground occurs on a specific circuit. AUX is supervised for shorts and earths only.
Open (NACs) -- Remove the end-of-line and make circuit impedance infinite.
Open (SLCs) -- Break the line anywhere in the loop.
Short -- Apply a zero ohm jumper across the circuit.
NAC illuminates the Trouble LED and the
NAC Trouble LED flashes
SLC illuminates the Trouble LED
SLC illuminates the Trouble LED
NAC illuminates the Trouble LED and the

AUX illuminates the Trouble LED
Earth Ground (NACs) -- Place a 10K
Ω
or smaller value resistor from the supervised wiring to Earth Ground.
Earth Ground (SLCs) -- Place a 100
Ω or smaller value resistor from the supervised wiring to Earth Ground.
If an Earth Ground occurs on any circuit the
Fault and Trouble LEDs both illuminate
