Description

The Kidde Hardwired Smoke & Carbon Monoxide Detector, AA Battery Backup, Voice Alerts, Interconnectable, LED Indicators, model 900-CUAR-V, is an alarm combo that detects smoke, fire, & carbon monoxide gas, using a single alarm. Operating through your home’s wiring (120V AC power), while 2-AA batteries (included) provide battery backup during the event of a power failure, the Kidde Smoke and Carbon Monoxide Alarm is equipped with self-testing components that are always checking the unit to ensure the device is operating as expected*. Photoelectric sensing technology that senses visible fire particles (associated with smoldering fires), while an electrochemical sensor detects carbon monoxide. When a smoke, fire, or carbon monoxide event occurs, the Kidde fire alarm warns with an 85-decibel alarm sound & flashing red LEDs, and voice alerts announcing, “Fire! Fire!”. For carbon monoxide detection, the alarm will sound with the announcement “Warning! Carbon Monoxide!”. When the smoke alarm is at the end of its life span, the detector will announce, “Replace Alarm!”. Three LED warning lights provide status of the alarm: a green status alerts to the alarm operating properly, amber alerts to faulty operation or connection, and red alerts to smoke, fire, or carbon monoxide.

  • Easy installation mounting bracket included for quick installation in 4 orientations
  • Photoelectric sensor detects visible fire particles associated with slow, smoldering fires, while the electrochemical sensor detects carbon monoxide
