Product Overview

  • Battery-operated Smoke and CO detectors (batteries included)
  • Voice warning system announces the threat detected
  • UL # KN-COSM-XTR-BA
Kidde’s Intelligent Alarm uses breakthrough technology to offer a faster response to real fires, including smoldering and fast-flaming, as well as offer warning of carbon monoxide (CO) and dramatically reduce the chance of nuisance alarms. In addition, the Intelligent Alarm contains a voice warning that clearly states the present danger – smoke or carbon monoxide – and announces “Fire! Fire!” or “Warning! Carbon Monoxide!”
  • Provides protection for smoke and carbon monoxide in one device
  • Voice alarm announces "Fire! Fire! Fire!", when a smoke or fire hazard is detected and announces "Warning! Carbon Monoxide" when a CO hazard is detected
  • 3 pack bundle
  • Smart hush feature temporarily silences nuisance alarms
  • Battery safe guard feature ensures that unit is not mounted without batteries installed
  • Low-battery warning alerts you when the battery needs to be replaced
  • Since carbon monoxide is present in all fires, having both detection chambers work together increases the alarm’s ability to discriminate between a true fire hazard and a nuisance alarm, such as shower steam
  • Product not available for sale in the state of California
  • UL/CSFM Ref. Kidde Part KN-COSM-XTR-BA

Since it is smoke detected, will cig. smoke make it go off?
Asked by: Snuggy
No, smoking does not set it off. I did have a small carpet fire and the smoke detector did NOT GO OFF. Makes me wonder how big a fire must be to set it off? Of course I tested it after the incident and it was working fine?

Can I use lithium batteries?

Asked by: 740
I read where lithium batteries can mess up the sensors so just use regular AA batteries to be safe.

I liked that the batteries were AA instead of the common 9 volt and unit was very easy to install with only two screws. This product has added life safety value with the combo smoke and CO alarm.

Rated 3 out of 5 by from seems ok It seems to be ok. It has worked when i tested it. I was told by a fire inspector to avoid the ionization type smoke alarms. He said the photo electric type are more reliable. I wouldnt have spent $40 on this one had I known that.

Rated 5 out of 5 by from 7 yr lifespan, worth price mine just went out last week, after 7 years of faithful service, with no malfunctions along the way. Kiddie makes a great detector, and they have never let me down. This is a great buy, but they do have an even better model out now. This time around, I will be upgrading to the li-ion battery version with a 10 year lifespan ... that's three extra years of expected life, and no batteries to change, plus you get to keep all the same features. And at about $10-$15 more than the standard AAA version, the "higher" price really just buys all those AAA's that you won't need to install... saving you time, and putting less batteries in a landfill!!

THREE DIFFERENT KIDDE SMOKE/CO ALARMS HAVE HAD THEIR ALARM GO OFF IN MY HOME IN THE MIDDLE OF THE NIGHT, WITHOUT ANY SMOKE OR FIRE. THE LAST TIME THE LOCAL POLICE WERE SUMMONED WHEN THE ALARM WENT OFF AND WE WERE NOT HOME AT THE TIME. EACH ALARM WAS ONLY ONE YEAR OLD OR LESS. I WILL NEVER PURCHASE THIS PRODUCT AGAIN.

You know, if the product didn't work, then it would be unlikely for me to be in any position to complain... It was easy to install and test. That's all that I know at this point. Let me add that there should be a combination detector on every floor of every inhabited home, and it should be checked periodically.

That's because even with the instructions telling you how many beeps for the smoke and how many beeps for the carbon dioxide you're not gonna remember when the time comes to act. That is the advantage of a talking product . you know exactly which one it is and what to do

Excellent quality A must have for everyone’s home these units saved my two daughters lives last year when my boiler failed in my house filled with carbon monoxide If it wasn’t for this detector going off and waking my daughters up it would’ve been definitely tragic
