The ADT Combination CO/Smoke 4 wire combines CO and smoke detection into one device, requiring less wiring and fewer back boxes than two separate devices.  Additionally, this detector cell can be easily replaced at end-of-life, resulting in a much lower life cost than having to replace the entire detector.

Installation ease:

The ADT Combination CO/Smoke 4 wire detector requires less wiring than two separate CO and smoke devices. So you can pre-wire its plug-in base, while its large wire-entry port and in-line terminals provide ample room for neatly routing wiring. The base accommodates several back box options and also direct mounts using drywall anchors. The head also plugs into the base with a simple Stop-Drop `N Lock™ action. When the detector’s CO cell reaches endof-life, it can be easily replaced in the field without a tool.

Intelligence:

With the help of the module, this detector transmits distinct CO and smoke signals, allowing appropriate response from the central monitoring station. Additionally, intelligent features, such as drift compensation and smoothing algorithms, reduce nuisance alarms.

Instant inspection:

The detector LEDs enable instant inspection of detector status signaling normal/standby condition, alarm condition, maintenance/trouble condition or functional test mode. 2-wire devices allow loop testing via the EZ Walk feature where wiring can easily be verified by checking the LED status at each detector.
