Ratings & Reviews for First Alert BRK Hardwired (with Battery Backup) Ionization Interconnected Combination Smoke and Carbon Monoxide Detector

Ceiling frame must be replaced.

This is exact replacement for First Alert device but it will not connect to existing ceiling frame and must be replaced with the one provided. The wire connecter is fine.

False alerts galore

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.

Smoke detector fire alarm combo

It was very easy to install

Quick replacement for failing original

Product works fine. Even though it looked to be a direct replacement for original BRK since house was new, I had to replace the original bracket with the new bracket. They look identical, but just slightly different in size. Didn't need to use the new wiring (old wiring plugged in fine). The original lasted almost 20 years.

Easy to install

We bought this single unit because we needed to supplement the box of six units we purchased when updating/upgrading our outdated alarms.

An easy upgrade

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...

Good condition

Arrived onetime

Not to good

The tolerance between the ceiling attachment bracket and the detector was terrible. Before installation it took a major effort to remove the bracket from the detector since it was so tight.

Otherwise you couldn’t attach the detector to the bracket without the bracket being twisted off the ceiling.

dical6 Could have been simpler

I purchase the same unit I had before and the thought I could just attach it to the existing base. But the base size had changed and now I had to get a screw driver and undo and then reattach the new one. Very disappointed as I did not have to travel so far to get this brand unit if the base and unit were same size as before as I have 14 units to change and it would have made it much simpler. There was nothing new about this unit than the last one and the other one was a bit smaller.

Smoke Detector

Smoke and CO2 detector. Be sure the interconnection connector is the same as the ones being replaced.
