Units were ready to install as replacements for my old, hard wired units. Took me about an hour and a half to replace all six.

5 of 5 Great Product January 21, 2019
Reviewer: GRPilot from Toms River, NJ United States  
Needed to replace a hardwired smoke alarm that was quite outdated. The new alarm was very easy to install, and I like the fact that it is both a photoelectric and ionization type detector. The replaceable battery backup is a great feature.
