First Alert Battery Powered Slim Combination Smoke and Carbon Monoxide Alarm

  • First Alert's PRC700A is a battery-powered combination smoke and carbon monoxide detector with a mute button to silence any nuisance alarms. The button can also be used to test alarm functionality for ease of weekly testing. The alarm’s built-in photoelectric smoke sensor reduces nuisance alarms from cooking smoke or shower steam. It also utilizes an electrochemical carbon monoxide detector for increased accuracy. The PRC700A's slim design is half the thickness of a standard alarm, allowing it to easily blend in with your home's décor. It boasts a loud 85dB sound output and an LED indicator for visual confirmation. It also has a tamper resistant lock to prevent the battery and/or alarm removal and comes with an easy-to-open battery drawer: no need to take down the alarm from that ceiling to change the battery. An end-of-life signal will turn on when it's time to change the battery. 5-year limited warranty.
