Rated 3.5 out of 5 by 22 reviewers.
Rated 2 out of 5 by 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 that turns on by remote. The remote also sets off the alarm in her room, even though I'm pointing it to the opposite side of the room. It has scared her so much she demanded we take the moon out of her room. Twice my 1 year old got a hold of the tv remote and accidentally set off the one downstairs, scaring the heck out of both children. I'm getting models without the remote control feature. I'm deducting points based off our experiences. December 31, 2011
Rated 5 out of 5 by Works great and loud Loud voice. Installed two on first floor and one on second floor. Easy to install. January 29, 2014
Rated 4 out of 5 by Small Problem Resolved Purchased several for the house. Replaced one of the units that were defective which kept alerting carbon monoxide even though there was none. July 15, 2014
Rated 4 out of 5 by 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, a remote control or energy saving light bulb probably is setting it off, disable the IR sensor and it will stop". It was simple, Open the battery door with the batteries in, hhold down the test button while closing the door, a chirp will sound and then the IR mode is disabled. So far no more problems. Otherwise it is a smoke/CO alarm that sits there and doesn't do anything exciting. March 31, 2013
Rated 1 out of 5 by Had to Return 2 Units Due to Malfunction I had to return 2 out of the 3 units I purchased due to alarm malfunctions. Both times they started beeping 3 times in the middle of the night indicating a malfunction. They were almost brand new when this occurred. I no longer trust the third unit and will probably return it too. Avoid this alarm unless you like to be woken up in the middle of the night for false alarms! May 31, 2014
