System Sensor C01224TR Carbon Monixide Detector

The System Sensor C01224TR is a round, four-wire, system-monitored carbon monoxide detector designed for indoor fire and life safety applications. Operating from a nominal 12/24 VDC supply, it uses an electrochemical sensing cell to detect carbon monoxide and provides local audible and visual notification. The detector incorporates RealTest technology, allowing technicians to perform a functional CO gas test using an appropriate test agent. A built-in Form C alarm relay and Form A trouble relay provide system monitoring capabilities, while dual LEDs indicate operating and alarm conditions. The unit includes a Test/Hush button, low-current operation, and a compact round housing suitable for wall or ceiling installation. The detector is listed to UL 2075 and has an 85 dBA minimum audible alarm at 10 feet. Its sensor has an approximately six-year end-of-life timer, helping identify when detector replacement is required.
