First Alert BRK SMI100-AC Hardwired Smoke Detector with Battery Backup, 6-Pack

Great purchase. Easy to install and replace the old smoke & carbon detectors. The 6 pack was enough to replace all of my detectors.

Installed these across our home and feel so much safer. The hardwired setup with battery backup is exactly what we needed. They’re reliable, easy to install, and the interconnect feature ensures we’re alerted no matter where the issue is. Peace of mind in a box!

These worked great to replace some older FireX detectors. They screwed right into the existing locations, and with the adapter harnesses it was all plug and play. Replaced 10 detectors in less that 30 minutes.

Bought these to replace my 5 year old hard wired smoke detectors. Easy to install. Could use the existing mount with no problems in installing on mount. Change battery annually. The brand is the same as the one I replaced which was a good smoke detector. Affordable smoke detectors that last about 5 years. Highly recommended.

Great alarms for a great price. Easy to install and link together perfectly.

Now installed and workng fine.

The six pack is a bargain. Wiring is easy, but you can buy plug in adapters.

Easy replacement for our original smoke detectors. Fit perfectly.
