Fire-Lite CMF-300 Control Module

The Fire-Lite CMF-300 is an addressable control module designed for compatible Fire-Lite intelligent fire alarm control panels. It provides a supervised output circuit for controlling notification appliances such as horns, strobes, bells, and other compatible signaling devices using an external power source.

The module communicates over the Signaling Line Circuit (SLC), allowing the fire alarm control panel to individually activate notification circuits through system programming. Featuring rotary address switches, LED status indication, and support for Class A or Class B wiring, the CMF-300 is ideal for commercial fire alarm applications requiring intelligent notification control. This product is intended exclusively for commercial fire alarm installations.

Product Functions

• Controls notification appliance circuits (NAC)
• Activates horns, strobes, bells, and compatible signaling devices
• Supports supervised Class A (Style Z) or Class B (Style Y) circuits
• Provides individual address identification
• Supervises notification circuit wiring
• Reports module status to the fire alarm control panel
• LED status indication for polling and alarm operation

Electrical & System Information

The CMF-300 operates from a compatible Fire-Lite Signaling Line Circuit (SLC) with an operating voltage range of 15–32 VDC. Notification appliances are powered by an external regulated 24 VDC power supply, while the module supervises the notification circuit and controls the output relay.

The module supports Class A (Style Z) or Class B (Style Y) notification appliance circuits and includes a 47 kΩ end-of-line resistor for circuit supervision. Rotary decimal switches provide simple field addressing.

Features

• Commercial addressable control module
• Supervised notification appliance circuit
