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 MMF-302 Interface Module is intended for use in addressable two-wire systems, where the individual address of each module is selected using the built-in rotary switches. This module allows addressable panels to interface and monitor two-wire conventional smoke detectors. It transmits the status (normal, open, or alarm) of one full zone of conventional detectors back to the control panel. All two-wire detectors being monitored must be UL compatible with this module.
The MMF-302 has a panel controlled LED indicator and can be used to replace an M302 module in existing systems.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, these modules shall be connected to listed compatible system control panels only.
In addition, please refer to Fire-Lite Device Compatibility document number 15384 for the list of compatible detectors.
FIGURE 1. CONTROLS AND INDICATORS: MOUNTING
The MMF-302 mounts directly to 4-inch square electrical boxes (see Figure 2).
The box must have a minimum depth of 2 1⁄8 inches. Surface mounted electrical boxes (SMB500) are available.
WIRING
NOTE: All wiring must conform to applicable local codes, ordinances, and regulations. This module is intended for power-limited wiring only.

1. Install module wiring in accordance with the job drawings and appropriate wiring diagrams.
2. Set the address on the module per job drawings.
