Hardwired (AC) & Interconnected Smoke Alarms

Kidde offers fast and reliable hardwired smoke detection for every room in your home. Review our hardwired AC and interconnectable smoke detectors. Interconnected smoke alarms link together — so when one detects a problem, they all sound. Instead of each alarm working solo, they're kind of like a home safety super team.

Replacing an old First Alert™ or BRK™ smoke alarm? Make the job quicker by adding a KA-B Quick-Convert Adapter to each new alarm. View the specifications first, to ensure compatiblity.
