Description
The Notifier FMM-1 Intelligent Monitor Module delivers reliable supervision and control for addressable fire and security systems. Designed for use in two-wire or four-wire fault-tolerant Initiating Device Circuits (IDCs), it continuously monitors connected devices—such as smoke detectors, manual pull stations, and supervisory contacts—and reports normal, open, or short-circuit conditions back to the fire alarm control panel.
Key Features & Benefits:
- 2-Wire/4-Wire Fault-Tolerant IDC: Supervises normally-open fire-alarm or security devices with Class A or Class B wiring.
- Rotary Decimal Addressing (01–159): Built-in switches let you assign a unique module address quickly, enabling pinpoint location reporting.
- LED Status Indicator: Panel-controlled bi-color LED flashes in normal operation and latches steady on alarm or trouble for easy visual checks.
- Power Switching Capability: Switches external DC power or audio amplifier lines to notification appliances, reducing the need for separate control modules.
- Built-In Type Identification: Automatically identifies itself to the control panel as a monitor module—no special programming required.
- Fault-Tolerant Wiring Terminals: Dual pairs of output terminations support supervisory Class A circuits for enhanced reliability.
- SEMS Screws with Clamping Plates: Simplify wiring installation and ensure secure connections.
- UL Listed (Fire & Burglar): Approved for intelligent fire alarm systems and commercial proprietary burglar-alarm applications.
Applications:
- Addressable Fire Alarm Systems: Monitor and supervise IDC circuits for smoke detectors, pull stations, and waterflow switches.
- Security Systems: UL-listed for commercial burglar-alarm use, supervising door-contacts and tamper switches.
- Retrofits & Upgrades: Direct replacement for older MMX-1 modules—modernize existing panels without rewiring.
With its compact design, flexible wiring options, and robust supervision features, the Notifier FMM-1 streamlines installation and enhances the reliability of life-safety and security installations.
