The First Alert SMI100-AC delivers precision smoke detection through advanced sensing technology, engineered for dependable fire safety in residential environments. This hardwired alarm operates on standard AC power with integrated battery backup, ensuring uninterrupted protection during power disruptions. The interconnect capability allows multiple units to communicate throughout your home, triggering coordinated alerts that alert occupants across all connected zones simultaneously. Precision detection technology minimizes false alarms while maintaining rapid response to genuine fire threats. Built with First Alert's proven reliability standards, this detector provides the early warning performance homeowners trust for comprehensive fire protection.

Interconnect Hardwired Smoke Alarm with Battery Backup

The First Alert SMI100-AC Interconnect Hardwired Smoke Alarm with Battery Backup complies with updated industry regulations and features First Alert’s advanced Precision Detection sensing technology. Designed for straightforward installation, this hardwired smoke alarm does not require any rewiring. It is compatible with other interconnectable alarms, allowing you to build a comprehensive home alert system for early warning in case of smoke or fire.

Early Warning Interconnect

In addition to functioning independently, connect multiple hardwire detectors together to create an alarm system throughout your home. When one interconnect alarm sounds, all connected detectors will sound to help provide an early warning and time to safely escape. Integrate with up to 12 other First Alert or BRK detectors and 6 other compatible devices. Please reference user's manual for compatible alarms. If the alarm system sounds, the latching alarm indicator will visually identify the unit that initiated the alarm.

Hassle-Free Installation

Easily install and replace existing hardwired smoke alarms by using the hardwire quick connect plug. There is no need to rewire into your home's electrical system. Although the First Alert SMI100-AC interconnect smoke alarm is designed for hardwired installation, it also features a battery backup to help provide continuous protection in the event of a power outage. Discourage unauthorized removal of the backup battery or alarm by using the optional locking features.

Easy to Maintain & Test

Use the test/silence button to test smoke detector regularly. This will help ensure it is working properly and also silence false alarms. A low battery alert will let you know when it's time to replace the backup battery and the end-of-life warning will let you know when it’s time to replace this 8th generation smoke detector completely. See user's manual for information on how and when to test and replace alarms.

Upgrade to 8th Generation Alarms

First Alert’s Precision Detection Advanced Sensing Technology complies with the most recent safety regulations. As a result, this smoke alarm excels at telling the difference between non-threatening cooking smoke and actual fire hazards. Furthermore, 8th edition smoke alarms are capable of sensing smoke produced by burning synthetic materials, which are frequently found in today’s homes. This leads to fewer unnecessary false alarms and provides vital early alerts during fire emergencies.
