First Alert - SMICO100 Battery-Operated 2-in-1 Smoke and CO Alarm, Ionization - White

Hardwired photoelectric smoke alarm with Precision Detection provides early warning of home fires while helping to reduce nuisance alarms from everyday cooking. Voice and location alerts clearly announce where smoke is detected, and interconnect capability ensures all compatible alarms sound together for whole-home protection. Integrated battery backup keeps the 85 dB alarm operating during power outages, and a large test/silence button simplifies maintenance.

The First Alert® SMICO110 10-Year Battery Smoke and Carbon Monoxide Alarm provides reliable 2-in-1 protection against both fire and carbon monoxide in an easy-to-install detector. Featuring superior safety features like a 1-touch test/silence button to confirm the combination alarm is functioning correctly and silence false alarms, the combination alarm features a built-in 10-year sealed battery that provides uninterrupted power for the life of the detector. No need to worry about the cost or hassle of battery replacements for a decade. An end-of-life warning lets you know when the alarm should be replaced.

Install this First Alert® SMICO100-AC Hardwire Smoke and CO Detector as a single alarm or interconnect multiple, compatible ones together to create an alarm system throughout your home. All connected alarms will sound when 1 in the series is alerted to help provide an early warning. Integrate with up to 12 other First Alert® or BRK® alarms and 6 other compatible devices. Reference user's manual for compatible detectors. If the detector system sounds, the latching alarm indicator will visually identify the device that initiated the alarm. The SMICO100-AC includes an adapter plug to allow for easy installation or replacement of existing hardwire alarms. It is also equipped with a battery back to provide continuous protection during power outages. Help stop unwanted removal of the detector or backup battery using the optional locking features. Ensure the hardwire combination alarm is working properly using the single test/silence button located on the front of the device. A low battery warning will let you know when it's time to replace the backup battery and an end-of-life warning will let you know when it's time to replace the detector completely. See user's manual for information on how and when to test and replace detectors.
