System Sensor monitor modules provide an interface to contact devices, such as security contacts, waterflow switches, or pull stations. M500DM is capable of Class B supervised wiring to the monitored device. 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 detection of impedance changes in the supervised loop to the monitored device.
