HARDWIRED SMOKE AND CARBON MONOXIDE DETECTOR WITH 10-YEAR SEALED BATTERY BACKUP

The First Alert SC9120LBL alarm boasts a dual ionization smoke sensing chamber and an electrochemical carbon monoxide sensor, along with an 85dB horn and a "silence" feature. This alarm is equipped with a 10-year battery backup, and the battery drawer is shipped pre-locked to prevent premature battery disposal. Under normal conditions, the battery should not require replacement for the life of the alarm.

The "Intelligent Sensing Technology" system is designed to reduce nuisance alarms, and the "Latching Alarm Indication" feature remembers which unit initiated an alarm. When interconnected in a series, the unit that triggered the alarm will rapidly flash its red LED indicator. After the alarm condition subsides, the initiating unit will store the information in memory and begin to flash the LED indicator 2 seconds on, 2 seconds off.

The "Perfect Mount" system features a gasketless base and a mounting bracket that keeps the alarm secure over a wide rotation range, allowing for true alignment. Other contractor-preferred features include a dust cover to keep the alarm clean during construction, and keyhole slots in the mounting bracket that eliminate the need to remove the electrical box screws for installation. Two locking features are provided to prevent battery theft and/or theft of the unit. Connection to AC power is made with a "Quick Connect" wiring harness, making installation quick, easy, and cost-effective.

This hardwired smoke or carbon monoxide alarm requires a 120V household electrical circuit (unswitched 120VAC) and a standard wiring junction box, either on the ceiling or wall, measuring 4 inches (10 cm) in size.

The First Alert SC9120LBL alarm keeps your family safer with its 10-year battery backup, ensuring constant monitoring even during power failures. It features an electrochemical carbon monoxide sensing technology and intelligent smoke sensing technology to reduce nuisance alarms. The keyhole slots in the mounting bracket simplify installation by eliminating the need to remove the electrical box screws.

The alarm's indicator lights display the presence of smoke or carbon monoxide, while the 85-decibel siren provides a clear, loud warning upon detection. With a single test/silence button, the alarm is easy to use. The included 10-year lithium battery features a locked drawer to prevent tampering.

Rigorously tested to meet UL standards, the First Alert SC9120LBL alarm emits a T3 pattern and comes with a 10-year limited warranty. As the most trusted brand in home safety since 1958, First Alert offers faster turnarounds on job sites with its easy-to-install, reliable alarms.
