Quick and easy! It will be nicer though if the functionality of its operations can be either AC or AC plus battery. It appears that it is designed to be AC and battery thus requiring battery to be replaced when it gets low with the recurring chirps. Then again, if the regulations call for the mandatory battery backup to exist, my preference would be invalid.

Easy installation for replacement

Reviewed: 10/14/2020 by Dan Guss

I recently installed 6 of these units in our home to replace 10-year old first alert detectors. The old detectors worked flawlessly for 10 years, but had reached the end of their expected life. Those old detectors in turn replaced the 6 original units in our house built in 1999. I was pleased to find that the wire harnesses and detector mountings are still the same for this model. All I had to do was unplug the old units, and remove them, simply plug in the new units to the harnesses and twist them in place and check their operation. It took about 45 minutes to do the entire job slowly and deliberately, and the new units are operating perfectly.

Amazons Price Gouging

Reviewed: 03/24/2020 by S Thomas Church Jr

I needed to replace an old First Alert hardwired Smoke Alarm that was still working after 30 years in my finished basement. It was discolored so I called First Alert and was given the exact replacement. Once I had the model number I tried to find it on Amazon but they showed multiple versions so I called First Alert again and the tech asked me how much did it cost and he was amazed that it cost 4 times what First Alert Store offered on line. I immediately ordered the replacement with free shipping and saved over $30 versus Amazons price. I recommend that anyone that is planning on purchasing First Alert Smoke alarms that they call the First Alert on-line store always. Plus I had on-line excellent technical help on how to uninstall and install the smoke alarm. This is not the first time that I realized that Amazon practices price gouging, in fact, I am awaiting an investigation from Amazon as to why a physicians practice offers an identical item for 10% higher price.

Changed out 10 year old detectors with these units, simple. All 10. They look nice, cause my wife said they had to be nice looking, really! ok fine. It's Saturday and it might be date night so... Actually I had her replace one or two. Easy battery replacement access, interconnected testing modes, cute lights and not expensive. One note, this model use ionization so you might want to use a photodect model in your kitchen like I did since even turning the oven on made it go off. Maybe I should get her to clean oven, no! Different model, same brand and of course it look the same. Enjoy you Saturday!

I replaced a First Alert alarm like the one I had. For some reason it just kept chirping and new batteries made no difference. After checking several local retail stores and not finding an alarm like the one I had, I found the exact model online at First Alert. The order process was fairly easy and the alarm actually arrived ahead of the anticipated delivery time. The alarm was exactly like the one I had. I am totally non technical and would not attempt the installation so I had a friend install it and apparently the process was fairly easy and the alarm immediately worked when installed. Am very pleased to have been able to replaced an alarm with the exact model I already had. Very pleased with the entire process from ordering to receipt to installation and am quite pleased with the alarm.
