Our Review/Thoughts

A remodel project required inter connected alarms

I was able to tie three apartments together by using a mixture of 2 hardwire systems, and some battery

I was worried about my grandkids living in a two story home with a walkout basement

Mounting ring fit old screws for old unit

Thhese are great! I even placed them in my own one story home

Saved hundreds of dollars over hiring an electrician to do it
