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.

This smoke & CO alarm is UL Certified, with a 10-year limited warranty. Meets the requirements of UL 2034, UL217, NFPA72, (chapter 11 2002 edition) The State of California Fire Marshal, NFPA101 (One- and two-family dwellings) Federal Housing Authority (FHA), Housing and Urban Development (HUD).

FEATURES AND BENEFITS

• 2X the Detection - Alerts you to both smoke & CO using a single alarm.
• Self-Testing - Smoke & CO alarm is equipped with components that are always checking to ensure the device is operating as expected.*
• Whole-home Alarm Activation - Expand detection via hardwired connections to other Kidde alarms – when one alarm sounds, they all do.**
• Quick-Install Mounting Bracket - Included in the box for simple, easy installation in 4 orientations.
• AC-hardwired with battery backup - Powered by home’s electricity in order to provide reliable detection. 2-AA batteries provide smoke detector-carbon monoxide detector combo backup power during short-term power outages.
• Photoelectric smoke sensor - May detect visible fire particles associated with slow smoldering fires sooner than an ionization sensor.
• Electrochemical CO sensor - Provides accurate and continual CO protection during the product’s life, remains stable during temperature and humidity changes and resists reactions to household gases that may cause false readings or reduce sensitivity.
• One-Touch Button - Unique cat-eye button on the face of the detector performs the following functions:
  • Activates the Hush feature to temporarily silence nuisance alarms.
  • Tests the unit’s electronics and verifies proper operation.
  • Resets the carbon monoxide smoke detector combo during a CO alarm (Unit will re-enter alarm within 6 minutes of reset if 70ppm or more of CO is present).
  • Silences a low battery chirp for up to 24 hours. Silences the end of life chirp on this carbon monoxide detector and smoke alarm for up to 24 hours.

*Self-testing is not a substitute for a manual push test of the alarm. Perform a button test once per week to verify proper alarm operation
