Easy Install - Excellent Product August 12, 2017
Reviewer: Norm from NORTH OLMSTED, OH United States  
Smoke alarms were very easy to install.  I replaced ionization alarms that were installed by the builder.  The interconnect wiring and 120 VAC was already in place,so it was an easy job to connect the wiring for the new alarms using wire nuts from the previous alarms, install the new mounting ring, and attach the alarms.  I pressed the test buttons on each alarm and they all sounded.  Job done.
