AA Single Supervised Output Module


System Sensor’s analogue addressable 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, manual call points, water-flow switches, 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 the universal mounting box PMB125. Wiring terminals are easily accessible for troubleshooting.

The M500S Control Module provides supervised monitoring of wiring to load devices that require external power to operate, such as horns, strobes, bells, etc. Upon command from the panel, the M500S disconnects the supervision and connects the external supply across the load device, thereby isolating the external supply from the system. Analogue measurement of the supervised wiring is transmitted to the panel, allowing detection of impedance changes.
