Seems to work - IF YOU DISABLE THE IR PART!!!

 

Lots of complaints about the alarm going into test mode for no reason. I had the same problem. Took it down and it sat for months. I realized "HEY THERE IS A WARRANTY". When I called up customer service, as soon as I mentioned the problem... "Oh yeah,...

First Alert SMoke Detector

 

This is the safest type of detector becuase not only does it do smoke and carbon monoxide, but it is photoelectric. That means it detects even small amount of slow burning smoke which can fill a room before fire breaks out. Very Important to have all...

Unit fits the all in one category.

 

Great unit and remote testing feature using TV remote. Only concern is unit has a life expectancy of seven years.

Consumer review (homedepot.com)

The remote control feature is a major downside!

 

This is a good product, but for us the remote control sensor caused me to get rid of them. It only mentions using a remote to mute the alarm on the package, not the ability to "test" the unit by remote. My daughter has a moon that hangs on the wall...
