Firex Hardwired Smoke Detector with Photoelectric Sensor and 9-Volt Battery Backup

Ease of installation- anyone can do it

For the last few years I have only used firex. they are easy to install and I have used them to replace several that were about ten years old. Don't risk your family replace those old ones.

I bought my house three years ago, and have had weird malfunctions from the smoke detectors beyond the false alarms from the shower, etc. I took one down, and the date code on my old smoke detectors was from 1995. Over 20 years past the 10 year useful life! Apparently original to the house. I bought two 2-packs and this single unit for a total of five detectors. I chose the photoelectric because they have fewer false alarms and do NOT have any radioactive material like the ionization units do. I had to use the enclosed wire harness because the detector was not compatible with the old unit, but it was super easy to do since the wires were pre-stripped and tinned. It was easy to just screw the wire nuts on and poke everything back into the gang box. The only quibble I have is that you have to punch out the holes you want to use in the brackets, and it was REALLY HARD! I'm sure it was supposed to be pretty easy, given that it was on just one of the brackets. The rest took a lot of effort, one of them significant. Apparently a stamping problem in the manufacture. Other than that, I recommend them.

While pretty much all new smoke detectors come with a new wire harness, I like that these came with adapters as well. Between the five units, I used the adapters on two of them that were up high on my vaulted ceiling and required a bit of a reach. The faster and easier the installation, the safer it was for me to do. I changed the wire harness on the others because new wire is a good thing. :) I was grateful for the option.

No they do not. No screws are included. Other than that, I recommend them.

I had someone install these for me and it seemed very simple and basic. Because I upgraded my home I needed to have hard wire smoke detectors to meet the city code.

Purchased one to replace one installed 2 years ago. They work!! Life span is short, but if you can catch them on sale, they are worth it!!!

Easy to install, as they fit the existing base and electrical pigtail from my old detectors. They have been operative for a few weeks now, and so far no false alarms.

Good product I’m sure it will last for years.

Easy to install, tested well, hope it does the job if I ever need it!
