Kidde 900-CUAR Hardwired Smoke & Carbon Monoxide Alarm, Interconnectable w/ AA Battery Backup

This Hardwired Smoke & Carbon Monoxide Detector, Interconnectable with AA Battery Backup, model 900-CUAR, helps protect you and your family from two hazards - fire and dangerous carbon monoxide (CO) - in one unit. This smoke and carbon monoxide detector combo features self-testing components that are always checking to make sure the alarm is on and working. What's more, the included mounting bracket makes installation quick and easy. This carbon monoxide detector and smoke alarm is capable of being hardwired to other select Kidde alarms, to provide whole-home alarm activation. This setup allows interconnected Kidde alarms to sound in unison, helping to ensure that everyone in the house is alerted.

This is a photoelectric smoke alarm, meaning it may provide better detection of larger, visible fire particles (the kinds associated with slow smoldering fires). Fire safety experts advise using both photoelectric smoke detectors, like this one, and ionization smoke detectors which may be better at detecting small, less-visible fire particles (those that emit from fast-flaming fires). Install both throughout your home for optimal smoke & fire detection.

Fire: The red LED will flash and be accompanied by three long alarm beeps. The alarm will repeat this pattern until unit is reset or smoke is eliminated. Carbon Monoxide: The LED will flash, and four short alarm beeps will sound. This continues until the smoke & carbon monoxide alarm is reset or the CO is eliminated. Low Battery: One chirp and the LED will flash red. This pattern will continue every minute for the first hour. After the first hour the red LED will flash once every minute accompanied by the chirp sound. Alarm Memory: Alerts a user if smoke or CO has been detected in the last 24 hours. If smoke has been detected, the red LED blinks every 15 sec. If CO has been detected, the red LED blinks twice every 15 sec.
