Keep an eye on manuf date if buying in store

Would Recommend

Easy to replace my existing smoke detectors from the same manufacturer but because dimensions were slightly different, needed to replace bracket and pigtail connector. Couple of extra minutes per unit but not too difficult

Decent low cost First Alert replacements

Would Recommend

I got these because a couple of my smoke/CO alarms started to chirp from non-battery related causes. (They were about 13 years old and at the end of expected lifespan.) The install was a bit more involved than I anticipated because the connector plugs were different from the previous ones, but there was no hassle splicing in the new ones.

direct replacement for First Alert units

Would Recommend

Loved that it is a direct replacement for the units I have that were installed 11 years ago. Had to change out the mounting bracket but the holes lined up and the wiring plugs were the same.

False alerts galore

Would Not Recommend

Out of the 6 units, 3 have given false alerts in the first 2 months. All of them in the middle of the night. Junk.

An easy upgrade

Would Recommend

We were long overdue to replace our wired, battery backup smoke alarms and decided to upgrade to the hardwired, battery backup smoke and carbon monoxide detectors. After turning off the power supply on the circuit breaker that controls all of our detectors, the swap was relatively straightforward. The connectors from the original units were compatible with the new units. It was just a matter of unplugging the old and plugging in the new. We did find that the plugs were a little tricky to d...

Needs adapter

Would Recommend

Work great, but I needed an adapter for each one as I did not want to rewire all 9 of my hardwire smoke detectors. I used Kiddie last time and it is a different connector (figures). Luckily I found 12 packe of Kiddie to First alart addapters. Otherwise, great item

Replace aging hardwired detectors

Would Recommend

Our current 6 Kidde detectors were at their 10 year lifespan and needed replacing. This contractor pack was the perfect answer. Easy to install if you are handy at all. Less than 10 minutes each to remove and reinstall the new detector. They all talk to each other exactly as they should.
