The system-connected ADT Carbon Monoxide Detector Wired Round with RealTest® provides early warning of dangerous CO buildup by using electrochemical sensing technology to measure CO levels in the air. Furthermore, if a dangerous amount of CO is detected, then the detector will also alert residents through sounding as well as flashing a Temp-4 signal alarm. Finally, protection is guaranteed 24/7 by a central station, regardless of whether residents are away from home, sleeping, or already suffering from the effects of CO.

If you have an old expired one it should be easy to swap out and replace, see wiring diagram.
