First Alert 9120B Hardwired Smoke Detector with Battery Backup (6-Pack)

This 6-pack of First Alert hardwired smoke alarms is designed to provide reliable protection for your home. Each alarm features a 9-volt battery backup, ensuring uninterrupted monitoring even during a power outage. The ionization sensor technology efficiently detects both smoke and fast-flaming fires, triggering an 85-decibel alarm to alert you immediately.

For added convenience, the alarms come equipped with a single button that can silence any nuisance alarms and test the detector functions. Indicator lights on the alarms will notify you if smoke is detected. The latching alarm feature automatically identifies which unit initiated the alarm, even after the triggering conditions have subsided. Additionally, an end-of-life signal will let you know when it's time to replace the unit, enhancing your overall safety.

These alarms can be interconnected within a single-family residence, ensuring that when one alarm is triggered, all connected alarms will sound. This seamless integration provides comprehensive coverage throughout your home. However, it's important to note that the wiring polarity must be correct, and all wire nut connections should be secure. A loose neutral (white wire) connection within the home junction box could lead to device malfunction.

For optimal protection, it's recommended to place one alarm on each level of your home and in each bedroom. The hardwired design, along with the included tamper-resistant locking brackets and universal mounting brackets, make installation a straightforward process.

Rigorously tested to meet UL standards, these smoke alarms emit the T3 pattern, a recognized signal for fire alerts. With the battery backup feature, you can rest assured that your family's safety is prioritized, even during a power outage.

The 6-pack format enables faster turnarounds on job sites, providing contractors and professionals with the most trusted alarms in home safety. The easy-to-access battery drawer allows for simple battery replacement without the need to dismount the entire alarm.

As a brand, First Alert has been a leader in home safety since it introduced the first residential smoke alarm in 1958. Trusted by homeowners and professionals alike, these hardwired smoke alarms offer reliable protection for your family.
