Addressable monitor modules supervise dry-contact input devices — such as waterflow switches, tamper switches, and conventional detector zones — and report their status back to the fire alarm control panel over a two-wire SLC. The MMF-300 occupies a single address on the loop, allowing the panel to distinguish its exact location and input state. It supports both LiteSpeed and CLIP protocols, making it compatible with Fire-Lite ES-200X, ES-50X, and MS-9050 panel families.

Verify panel/device family compatibility before ordering.
