Smoke detector

I love my First alert smoke detector. I love the fact that I can order directly from the company and not have a middle middleman.

Easy to Install

Just installed the 9120B Smoke Alarm after painting the hallway celling. This model was the replacement for the smoke alarm that was installed in the celling since 1992, it was really time to update it and it was very easy to do. The alarm looks great and it appears to be doing what it suppose to do, monitoring for a fire. I like it, no false alarms and I think it will last 10 years with no problem.

I replaced all of the smoke detectors in our home, and chose these after a lot of research. Good value, good price, and easy to install.

Unit tested as described in the instructions. Unit fitted nicely on the same place of the old unit without having to do any additional alteration and installation was quite easily by following all the steps in the installation instructions.

Low cost, fast shipping, great service

When my wired First Alert smoke alarm died after 8 years, I was happy to find an identical one on firstalertstore.com, at low cost with fast shipping.
