Supervisory Devices

Temperature, Water and Line Supervision

These devices watch conditions rather than intruders, and they report on the same zone inputs an alarm panel already has, which is why they end up on an alarm system instead of a building management system.

The temperature sensor is a closed circuit detector that opens at 40 F, rated 24VDC at 120mA, which is the classic freeze warning on a pipe run or an unheated store. Water level sensors detect the presence of leaks or the absence of water in tanks, in wired and wireless versions.

End of line relays are adaptable to all standard 4 or 6 wire fire systems and provide 12 or 24 VDC end of line supervision, approved by both U.L. and the CSFM.
