Smoke detector
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!

Simple Installation, Economical
I replaced my old alarms with this 6 pack, it's perfect because my house had 6 of the same make and model, 2 screws and a plug in is all it took. An electrician quoted me $2200, I asked if he was out of his mind! I did it myself for less than $100
