FIRST ALERT BRK SC9120FF Hardwired Smoke and Carbon Monoxide (CO) Detector with Battery Backup, White

The BRK SC9120B hardwire combination smoke and carbon monoxide alarm is a simple yet comprehensive unit that detects two distinct hazards. Carbon monoxide (CO), a colorless, odorless, and deadly gas, can be emitted by various sources including gas or oil furnaces, gas clothes dryers, water heaters, fireplaces, wood stoves, charcoal grills, gas ranges, and space heaters. Improper venting, clogged chimneys, and attached garages can also lead to the accumulation of this dangerous substance.

Featuring an electrochemical carbon monoxide sensing technology and an ionization sensor for smoke detection, the BRK SC9120 hardwire combination smoke and CO alarm with battery backup provides constant monitoring and reliable warnings. The 85-decibel siren emits a clear, loud alert upon the detection of either smoke or carbon monoxide, while indicator lights on the unit's face display the presence of these hazards.

For added safety, the alarm can be interconnected with up to 18 compatible devices, including 12 other smoke alarms and 6 compatible devices such as bells, horns, repeaters, and door closers. When one unit triggers an alarm, all interconnected alarms will sound, ensuring a comprehensive warning throughout the home.

Designed for easy installation and maintenance, the BRK SC9120 features a quick plug-in power connector, a single test/silence button, a side-loading battery compartment, and tamper-resistant locking brackets. The universal mounting brackets further simplify the installation process, allowing for faster turnarounds on job sites.

Backed by a 10-year limited warranty, the BRK SC9120 hardwire combination smoke and CO alarm with battery backup is UL-listed to safety standard 2034 for residential carbon monoxide alarms. The included 9-volt backup battery ensures constant monitoring, even during power outages, providing peace of mind for homeowners.

First Alert, the brand trusted in home safety since launching the first residential smoke alarm in 1958, has designed the BRK SC9120 to meet the highest standards of quality and performance. With its comprehensive features and rigorous testing, this hardwired alarm offers a reliable solution for protecting families from the dual threats of smoke and carbon monoxide.
