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

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bought this single unit because we needed to supplement the box of six units we purchased when updating/upgrading our outdated alarms.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

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.

Good product

It’s easy and quick.

Just follow the instructions

Ease of installation

BRK Smoke and Carbon Monoxide Alarm

Seems to be working as it should. I like the battery slit location on the side of the alarm. Others are under it do you have to untwist the entire alarm from the ceiling to get to the battery location.

Easy Replacement.

This detector is the updated replacement for the detectors originally installed in my home. It is an exact replacement and does not even require any rewiring. Just plug and play.

Easy install
