MIX-M502M Zone Interface Module



Product Description

Mircom’s intelligent module products are designed to meet a wide range of applications. Monitor and control modules can be used to supervise and activate sounders, strobes, door closers, pull stations, water flow switches, conventional smoke detectors, and more. Each module is rigorously designed and tested for electromagnetic compatibility and environmental reliability, in many cases exceeding industry standards. Modules are addressed with easy-to-use rotary code switches. Full size modules mount in standard 4″ x 4″ x 2-1⁄8″ junction box. Wiring terminals are easily accessible for troubleshooting purposes.

MIX-M502M Zone Interface Module
The MIX-M502M Zone Interface Module allows Mircom’s intelligent panels to interface and monitor two-wire conventional smoke detectors. All two-wire detectors being monitored must be UL or ULC compatible with the module. The MIX-M502M is addressed through the communication line of a Mircom intelligent system. It transmits the status of one zone of two-wire detectors to the fire alarm control panel. Status conditions are reported as normal, open, or alarm. The interface module supervises the zone of detectors and the connection of the external power supply.
