All I had to do was, plug them in and install on existing bases. I was surprised the old ones would last this long but am sold on First Alert.3 hardwired/battery backup - 10/24/2017 Reviewer: Charles Stauffer I just installed the 3 units that I ordered and they are working just great! Every home should have several smoke and CO alarms.- 06/13/2017 Reviewer: Robert Sines Replaced s with 9 new ones. Only small hassle was mounting ring was a different diameter than the old ones but that is an easy problem to get past... Great service - 05/22/2017 Reviewer: Terry Patti Technical person Tiffany provided proper information to replace model that no longer existed. shipped product quickly and at a very reasonable rate.Awsome Product - 05/05/2017 Reviewer: Byron Rieckman Well I installed a system of 9120b interconnected smoke alarms and they worked better than the older product, a brk smoke detector which had outlived its usefulness.The combination of a Battery Backup that provides optimal protection in the event of a power outage and an increased emphasis on the unit's 85d output establish the ultimate in peace of mind.
These alarms are also capable of interconnecting with up to 18 other First Alert or BRK hardwired alarms.- Doc Meek, South Jordan, Utah Quality and simple installation - 04/24/2017 Reviewer: Don Weiss Once I received the new First Alert smoke alarms, I was pleasantly surprised to find both contained batteries.Installation was less than 5 minutes to replace both bad units. Pleased with product and service - 03/14/2017 Reviewer: Kurt Eddy The person that took my order was knowledgeable and kind. I was motivated to replace my alarms due to a house fire in my region and that killed three children.I recommend you use First Alert/BRK products Great product, great service - 04/28/2017 Reviewer: J COLLINS MEEK Got the right product in jig time to install throughout my home.So nice to know that the smoke alarm will last for ten years with timely battery changes!
