Product Overview

Early Warning Interconnect

The SMICO105-AC interconnect Smoke and CO Alarm with 10-year battery backup provides reliable 2-in-1 protection with superior features. It can stand alone or be interconnected with other compatible alarms to create an alarm system throughout your home. When one hardwire detector sounds, all connected alarms will sound to help provide an early warning to a fire or carbon monoxide emergency. Integrate with up to 12 other First Alert or BRK detectors and 6 other compatible devices. Reference user's manual for compatible alarms. If the interconnected alarm system sounds, the latching alarm indicator will visually distinguish the unit that set off the alarm.

Hassle-Free Installation

Using the hardwire quick connect plug, easily install and replace existing hardwire detectors with no need to rewire into your home's electrical system. The SMICO105-AC interconnect Combination Smoke and Carbon Monoxide Alarm is designed for hardwired installation but also features a 10-year battery backup to help provide continuous protection in the event of a power outage. Prevent unwanted removal of the alarm using the optional locking feature.

Easy to Maintain & Test

The 10-year backup battery eliminates the need for battery replacements for a decade. Use the test/silence button to test the combination detector regularly to check that it is working properly and silence false alarms. Detectors don't last forever and the end-of-life warning will let you know when it’s time to replace the alarm all together. See user's manual for information on how and when to test and replace alarms.
