AA Single Input 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 M500M module interfaces with contact devices such as water-flow switches, providing full supervision of monitored circuit wiring. Conventional 4-wire smoke detectors can be monitored through the alarm and fault contacts, wired as an initiating circuit to the module. In addition to transmitting the supervised state of the monitored circuit (Normal, Open or Short/Alarm), the full analogue supervision measurement is sent to the panel, allowing detection of impedance changes in the supervised circuit.
