Worry Free 10-Year Living Area Sealed Lithium Battery Operated Smoke Alarm

The Kidde Smoke Detector, 10-Year Battery, Photoelectric Sensor Smoke Alarm, model p3010l, uses photoelectric sensor technology to detect visible fire particles (associated with smoldering fires). When smoke or fire is detected, an 85-decibel alarm will sound. The Kidde Smoke Detector is powered by a 10-year lithium battery, for coverage during a power failure, while eliminating the need for battery changes. A test-hush button allows you to test the battery operations as well as silence nuisance alarms that may occur from cooking or shower steam. The Kidde Smoke Detector will chirp when it's time to replace the battery. Install a smoke detector & carbon monoxide detector on every level of your home and near bedrooms to help keep your family safe from fire & poisonous gas. UL Listed with a 10-Year limited manufacturer warranty on the alarm only (not a battery performance claim). Warranty begins when the alarm is powered on. If that date is unknown, it should be assumed that replacement is needed. Meets requirements of UL 217, NFPA72 (chapter 11 2002 edition), NFPA101 (One and two-family dwellings), and Federal Housing Authority (FHA).
