Description
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. 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 hardwire smoke alarms 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 using the optional locking features. Easy to Maintain & Test: Use the test/silence button to test the interconnect hardwire smoke alarm regularly to help ensure it is working properly and 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 the alarm completely. See user’s manual for information on how and when to test and replace detectors.
