These were a direct replacement for my old smoke detectors. I had to replace a total of seven alarms. Each one took less then five minutes a piece. Very Easy!

Loud! But a great alarm! I tested it with smoke, & it works great! I have a BRK 9120B. I had to put tape & cotton over the horn. Cause it was so loud. Im planning to get a First Alert Smart Strobe today. Great product! From, Carson

Wont get burned by buying direct from First Alert Store - 06/14/2011
Reviewer: Mark Shaw
I found the best selection, availabilty and price from First Alert Store. Super fast shipping and oh by the way the redesigned smoke alarms are better than ever. They slide effortlessly into the new holder and lock into place with a click. No more smoke alarms hangin from their wires having to continually reattach them. Safisfied all the way around.
