First Alert SC9120BA Hardwired Smoke and CO Alarm

The First Alert SC9120BA is a hardwired combination ionization smoke and carbon monoxide alarm that offers dual detection for enhanced safety. Operating on a 120-volt AC supply, this smoke detector employs an ionization sensor to effectively detect smoke from fast-flaming fires, while the electrochemical sensor accurately identifies carbon monoxide from various sources like faulty appliances and blocked chimneys. When a threat is detected, the alarm sounds a loud siren to alert you to potential danger. This device is designed to be connected directly to your home’s electrical system, making it easy to install using its universal mounting bracket that conceals drywall cutouts. The locking pins ensure the alarm remains secure, while the test/silence button allows for simple functionality checks and false alarm suppression. The SC9120BA is capable of integrating with up to 12 other First Alert or BRK hardwired alarms and features a latching indicator to pinpoint the unit that activated the alarm. Ideal for providing comprehensive coverage across larger spaces, this alarm is essential for protecting your home or facility from the dangers of carbon monoxide leaks and fire hazards.
