Product Overview

  • Battery-operated smoke and CO alarm; no hardwiring required
  • Change AA batteries every 6 months to avoid low battery chirp
  • Voice alert announces the type of hazard; ideal for bedrooms
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
  • Smoke and carbon monoxide detectors utilize an ionization sensor to detect fire hazards and sound an 85 db alarm when a hazard is detected
  • 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.

Battery Operated Smoke and Carbon Monoxide Combination Detector with Voice Alarm and Intelligent Hazard Sensing (3-pack) is rated 4.5 out of 5 by 362.
Rated 5 out of 5 by from Combination Smoke and Carbon Monoxide Alarm with Voice First Installed this Kiddie M/N# KN-COSM-B combo smoke/CO alarm in October of 2004. It worked fine the entire time it was installed. it uses (3) AA batteries not the typical 9V. The voice prompts (when testing and low battery) are clear and loud enough to hear easily. On the negative side, It hit it's built in expiration date the night before last at 3AM. (7 years and 1 month after the initial installation) Would be nice if they could build it to last 10 years - but then i guess they'd sell less of them because I plan to buy another.. Excerpt from the owners manual about built-in end-of-life countdown timer included below... (from page 5) • After seven (7) years of cumulative power up, this unit will “chirp” every 30 seconds. This is an "operational end of life" feature which will indicate that it is time to replace the alarm.

Is compatible with several different brands so you do not need to replace all of the detector to get them working with each other. It also comes with different adapters to fit the existing wired connector to this unit which eliminates the need to mess with any wire connections. I did have to change the base plate because this unit was slightly larger than the one I replaced. One of the best features is the battery door can be opened with a push button on the face of the unit so you do not have to take the unit down to change batteries.

The install is a breeze and the features are nice, like the talking portion of the system. The easy battery loading and using standard AA and easy front access will make maint a breeze for them, over the old 9V that they had to take down to replace batteries. Great product for a fair price.

Works great, better design than the old one that had to be removed to change the batteries, also even though it was redesigned it fit right onto the old base so I didn't have to change the mounting plate.
