BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer
to the control panel installation manual for detailed system information.
If the modules will be installed in an existing operational system, inform
the operator and local authority that the system will be temporarily out
of service. Disconnect power to the control panel before installing the
modules.
NOTICE: This manual should be left with the owner/user of this
equipment.
GENERAL DESCRIPTION
The NFX-MM1M monitor module can be installed in a single gang
junction box directly behind the monitored unit. Its small size and light
weight allow it to be installed without rigid mounting (see Figure 1). The
NFX-MM1M is intended for use in intelligent, two-wire systems where
the individual address of each module is selected using rotary decade
switches. It provides a two-wire initiating circuit for normally open
contact fire alarm and security devices.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module should only be connected to a
compatible control panel.

MOUNTING AND WIRING
NOTE: This module is intended to be wired and mounted without rigid
connections inside a standard electrical box. All wiring must conform to
applicable local codes and regulations.
1.
Connect the red (+) and black ( – ) wires to the positive and negative
leads of the communication loop.
2.
Connect the violet (+) and yellow ( – ) wires to a two-wire, normally
open monitoring line.
3.
Install the specified EOL resistor value to terminate the monitoring
line.
4.
Set the address on the module per job drawings.
5.
Install the module in the desired mounting location.
