Information About MMF-301
The MMF-301 is a compact Fire-Lite addressable monitor module designed for intelligent two-wire fire alarm control systems and installation directly behind the device being supervised. It monitors one Style B (Class B) initiating device circuit and reports normal, alarm, and trouble conditions to the compatible FACP through the signaling line circuit. Rotary decimal address switches provide direct device addressing from 01–159 on compatible MS-9600 Series systems and 01–99 on other supported systems, while an integral LED provides communication and alarm-status indication. Its miniature construction, high EMF/RFI immunity, 47 kΩ end-of-line resistor supervision, and SEMS terminals make the module suitable for both new installations and retrofit applications where mounting space is limited.
Key Features:
- Single-Circuit Monitoring: Supervises one Style B (Class B) initiating device circuit for compatible dry-contact devices.
- Intelligent Addressability: Provides individual point identification and status reporting through a compatible Fire-Lite addressable SLC.
- Compact Construction: Measures only 1.3 in H × 2.75 in W × 0.65 in D for installation in restricted spaces.
- Behind-Device Installation: Small enclosure allows installation in a single-gang electrical box directly behind the monitored device.
- Rotary Decimal Addressing: Provides straightforward device address selection without binary DIP-switch programming.
- Expanded Address Range: Supports addresses 01–159 on compatible MS-9600 Series panels and 01–99 on other supported systems.
- LED Status Indicator: Integral LED flashes during normal panel communication and can latch steady when the module enters an alarm condition.
- IDC Supervision: Monitors field wiring integrity using a 47 kΩ end-of-line resistor.
- Dry-Contact Compatibility: Supports normally open devices including pull stations, waterflow switches, heat detectors, and other contact-type initiating devices.
- Four-Wire Detector Monitoring: Can supervise compatible zones of externally powered four-wire smoke detectors.
- High Noise Immunity: Designed with high EMF/RFI resistance for dependable operation in electrically noisy environments.
- SEMS Wiring Terminals: Screws with clamping plates simplify secure field-wire termination.
The MMF-301 delivers the reliability and precision required for addressable supervision of conventional initiating devices in commercial fire alarm systems.
