Smoke Alarm 5 Pack - 120V Hardwired with Battery Backup

The First Alert 9120B Hardwired Smoke Alarm with Battery Backup is designed to promote greater household safety. This 120-volt AC smoke detector utilizes an ionization smoke sensor to reliably detect smoke from hot, fast-flaming fires and alerts you with a loud 85-decibel alarm.

The product is a hardwired alarm, and it is crucial to confirm that the wiring polarity is correct and all wire nut connections are secure. A loose neutral (white wire) connection within the home junction box could prompt a device malfunction.

Tamper-resistant locking pins and a single-button silence test feature are included in the design, ensuring the alarm remains secure and can be easily tested. The loud 85dB alarm provides a clear and effective warning in the event of a fire.

The smoke alarm is powered by 120-Volt AC with a 9-Volt battery backup, ensuring it continues to function even during a power outage. This backup power source helps to maintain the alarm's reliability and effectiveness, further enhancing the overall household safety.

Imported and designed with safety in mind, the First Alert 9120B Hardwired Smoke Alarm with Battery Backup is a reliable and efficient solution for detecting and alerting homeowners to the presence of smoke, contributing to a safer living environment.
