The CO1224TR Carbon Monoxide Detector with RealTest is a round version of the award-winning System Sensor CO1224T CO Detector.

Like the CO1224T, the CO1224TR includes RealTest - the first and only field functional CO test fully compliant with NFPA 720: 2009. Only RealTest enables installers to quickly verify that the CO detectors they install are actually protecting their customers. The CO1224TR provides multiple mounting options and is quick and easy to install, test, and maintain. With a low current draw, the latest electrochemical sensing cell, a six-year, end-of-life timer, and system connected 24/7 central station monitoring capability, the CO1224TR provides the most reliable protection available.
