M500X Isolator 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.

Monitor Module
Mircom’s monitor modules provide an interface to contact devices, such as security contacts, water flow switches, or pull stations. They are capable of Styles A and B supervised wiring to the load device (MIXM500M is capable of Style D). Conventional 4-wire smoke detectors can be monitored through their alarm and trouble contacts, wired as an initiating loop to the module. In addition to transmitting the supervised state of the monitored device (normal, open, or short), the full analog supervision measurement is sent back to the panel. This allows impedance changes in the supervised loop to the monitored device to be detected. The MIX-M500DM is capable of monitoring two separate Class B circuits simultaneously, making it ideal for water flow tamper switch and flow switch monitoring. The small size of the MIX-M501M allows it to fit inside devices or junction boxes behind devices.
