10-Year Worry-Free Hardwired Smoke, Carbon Monoxide Detector, Voice Alarm 21029893

About this item

The Kidde FireX P4010ACSCO (item 21029893) is an AC/DC powered combination photoelectric smoke and carbon monoxide alarm that contains a 10-year sealed battery backup and a built-in voice messaging system. During an alarm event, the 85 dB tone is accompanied by voice warnings, helping reduce confusion with clear verbal announcements such as "Replace alarm" at end of alarm life and "Hush mode activated" when a nuisance alarm is silenced. Kidde P4010 Series alarms contain 10-year tamper-proof sealed batteries, eliminating the need for battery replacement and ending worry over unauthorized removal. Users are further shielded from late-night battery chirps by the unit's Ambient Light Sensing feature, which establishes a day/night cycle and prevents alarm chirping in dark conditions. This hardwired detector connects to your home's electrical system, while the sealed 10-year battery keeps the alarm protected during power outages. Model: P4010ACSCO. Item number: 21029893.
