Description

The first alert SMICO100-AC  combination smoke/carbon monoxide alarm is perfect for protecting your family against the dangers of fast-burning fires. Hardwired directly into your home’s electrical system, this model also comes with a backup, 9V battery intended to provide emergency power in the event of power outages.

As a leading choice for accurate carbon monoxide and wired smoke alarm, the SC9120B provides the most optimal protection. Due to its Intelligent Sensing Technology, this first alert fire alarm reduces the frequency of nuisance alarms and comes with silencing options to quiet both low-battery chirps and unwanted alarms.

The SC9120B first alert model comes with easy, quick, and cost-effective installation and mounting. With a large opening and keyhole slots in the mounting bracket, access to the alarm’s wiring is quick while fully eliminating the need to remove the electrical box screws.
