End of line power supervision relay for 4 wire smokes
This four wire, power supervision relay is used with home security systems with a fire alarm control unit and smoke detector. The supervision relay is installed at the end of the detector power circuit. A break in the detector power circuit or a loss of power de-energizes the power supervision relay, opening the contacts and causing a trouble annunciation at the fire alarm control unit. Includes seven-inch color-coded leads (red, black, yellow, green, white).
* Works with any security system requiring power supervision
