Honeywell FIRE-LITE ALARMS MMF-302A User manual

MMF-302A Interface Module
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 opera-
tor and local authority that the system will be temporarily out of service. Dis-
connect 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-302A Interface Module is intended for use in intelligent, two-wire
systems, where the individual address of each module is selected using the
built-in rotary switches. This module allows intelligent panels to interface and
monitor two-wire conventional smoke detectors. It transmits the status (nor-
mal, open, or alarm) of one full zone of conventional detectors back to the
control panel. All two-wire detectors being monitored must be ULC compat-
ible with this module. The MMF-302A has a panel controlled LED indicator
and can be used to replace an M302A module in existing systems. MMF-302A
is capable of handling more than one detector in alarm condition.
COMPATIBILITY REQUIREMENTS
To ensure proper operation, this module shall be connected to a compatible
Fire•Lite system control panel only (list available from Fire•Lite).
MOUNTING
The MMF-302A mounts directly to 4-inch square electrical boxes. (See
Figure 2.) The box must have a minimum depth of 2.125 inches. Surface
mounted electrical boxes (SMB500) are available from Fire•Lite.
