Experience the next level of fire safety with the Kidde Hardwired Photoelectric Smoke Detector Alarm, 10-Year Lithium Sealed Battery Backup, model 20SA10, that uses photoelectric sensor technology to detect visible fire particles associated with smoldering fires. New, 9th Edition sensor technology reduces false alarms often caused by cooking or shower steam, while internal components of the smoke alarm self-test to ensure that it's always operating as expected. (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.) The Kidde Smoke Detectors' 5-inch design provides smoke detection for all living spaces such as your basement, living room, bedroom, kitchen, den, bathroom or crawlspace.

• Advanced Sensor Technology: photoelectric sensor technology provides advanced smoke detection in sensing visible fire particles associated with smoldering fires to reliably detect smoke or fire hazards
• Reduces Nuisance Alarms: sensor technology reduces false alarms often caused by cooking or shower steam
• Self-Testing Alarms: internal components ensure alarm is always operating as expected. 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.
• Peace of Mind: operates on a 120-Volt AC wire (installed in your ceiling) with a 10-year lithium battery that provides battery backup coverage during power outages & never needs to be replaced
• Early Warning Detection: upon sensing smoke or fire, an 85-decibel alarm sounds & a red LED will illuminate
• 3 LED Indicators: illuminate based on status of smoke alarm: green = operating properly, amber = fault in operation or error, red = smoke or fire indicated
