Ratings & Reviews for First Alert Brk 3-Pack Hardwired Photoelectric Sensor Smoke Detector

Good Smoke Detector

Nothing fancy about this smoke detector...it works as advertised. The only reason why I gave it 4 stars is that it didn't come with mounting screws. Other than that it works fine.

Much better than changing batteries...

Purchased these to replace others. Hope to never hear them work.

Easy to install with no problems.

This device was a direct change out of the same product that needed to be replaced. Was install with no problem.

Good quality, easy to install

I bought 6 of these units, to replace 15-year-old detectors. The new mounting brackets worked with the existing screw positions, so installation was extremely easy. I have not had any of the false alarms that some reviewers have mentioned.

Affordable and Easy Install Smoke Detector

First Alert AC Hardwired 120V Photoelectric Sensor Smoke Detector is an affordable way to keep you safe as it's constantly monitoring for smoke. It operates from standard household current with a battery backup in the event of a power failure. Quick and easy installation for replacing existing pre-wired smoke detectors. In most cases a screw driver is the only tool required.

Good smoke detector

Easy to install and easy to test. Hopefully we won't be needing it.

Effective unit

Of course one does not know if these units are effective without a life-altering event, but the installation and testing were simple and confidence inspiring. The instructions were clear and as a plus, the unit came with a fresh 9 volt battery.

This is the best smoke detector I have ever bought. Stylish, easy to install. It actually was put to the test saving me from a big fire. It got badly damaged by the fire, yet, it still works. Amazing smoke detector. Highly recommend it
