Features

  • 2 units in 1: unit alerts you to smoke & carbon monoxide by sounding a loud, 85-decibel alarm & sounding voice alerts
  • Ionization sensor technology senses invisible fire particles, while a electrochemical sensor detects CO gas
  • Voice Alarm & an 85-decibel alarm announces a hazard when detected: Fire! = smoke or fire or Warning Carbon Monoxide = CO gas, or "Replace Battery" when the battery needs to be replaced
  • Operates on 2-AA alkaline batteries, providing reliable detection during a power failure
  • Front-load battery door makes installation & replacement easy
  • Tamper-resistant design: deters removal of the carbon monoxide smoke detector combo from the ceiling
  • Test-Hush Button makes testing the detector or silencing false alarms easy (false alarms may occur from routine cooking, shower steam, dust or humidity)
  • UL listed with a 10-Year limited manufacturer warranty on the alarm only (not a battery performance claim). Warranty begins when the alarm is powered on. If that date is unknown, it should be assumed that replacement is needed.

Description

The Kidde Smoke & Carbon Monoxide Detector with Voice Alerts, Battery Powered, Combination Smoke & CO Alarm, model KN-COSM-BA, provides two fire safety detectors in one unit through the use of ionization sensing technology that senses invisible fire particles, while an electrochemical sensor detects carbon monoxide. When a smoke, fire, or carbon monoxide event occurs, the Kidde fire alarm warns with an 85-decibel alarm sound, flashing LEDs, and voice alerts. For smoke detection, the alarm will sound with the announcement, "Fire! Fire!" and a red LED will flash in unison with the voice alarm. For carbon monoxide detection, the alarm will sound with the announcement "Warning! Carbon Monoxide!". In the event of a low battery, the detector will announce, "Low Battery!" The Kidde combination smoke and carbon monoxide alarm is powered by 2-AA batteries, which provide coverage during a power failure. A convenient pop-up, front-door battery compartment allows for quick installation or replacement of a battery without having to disconnect the entire unit from the ceiling. In the case of nuisance or false alarm, the Smart Hush button silences the unit for approximately 8 minutes, which is helpful when this smoke detector carbon monoxide detector combo sounds from things like routine cooking or shower steam. When installed, the green LED on the alarm will flash every 60 seconds in standby condition, letting you know that the unit has power & is operating correctly. Install a carbon monoxide smoke detector combo on every level of your home and near bedrooms to help keep your family safe. UL Certified with a 10-year limited manufacturers' warranty. Meets requirements of UL 2034, UL217, NFPA72, (chapter 11 2002 edition) The State of California Fire Marshal, NFPA101 (One and two family dwellings) Federal Housing Authority (FHA), Housing and Urban Development (HUD).

    • Very Nice Solution for Our Needs -
Size: 1 Pack Style: Previous Model Pattern Name: Detector
In spite of the negative reviews, I decided to get this. And I am very glad I did! It's perfect for our application: we only live in a 700 sq ft place and only had need for one. The Pros: - Stand-alone operation - CO and Smoke Detection - Powered by only (2) AA batteries (much cheaper than 9V and I have lots of rechargeable batteries) - Hush Mode - IT WORKS... almost too well... (in spite of what some of the negative reviews say). - It's inexpensive! There is no down side I've seen (save the hush mode cancels itself when there's no smoke, rather than wait for the 9 minute timer to expire). The hush mode cancellation is hardly a big problem. It's just annoying when we roast coffee because we generate smoke about every 4 minutes for 15-20 minutes. Rather than 1-2 pushes on "hush" (if it was strictly timer-based) you have to push it every time you roast. Or just pull the batteries, then put them back in when you're done. It is VERY sensitive. We don't generate much smoke when we roast coffee, but even though the detector is quite a ways from the source with very good ventilation it still goes off every time. Someone who reviewed this very negatively complained it wouldn't go off with a lighter under it. That's because it's a SMOKE detector. That same genius complained that it wouldn't detect CO with a "scooter" running in a closed garage. Modern vehicles (even small engines) generate far less CO than they did decades ago. Modern vehicles with catalytic converters will generate almost zero CO. One would need to get a lot more creative to test the CO alarm at home. I will not suggest how. I haven't tried. But I'm comfortable with Kiddie's reputation and if the smoke detection is any indication, the CO detection is probably performs as they say it does. Another reviewed blasted it because the "voice" was so quiet. For a combo detector under $30 who cares? Are you going to stand under a blasting alarm (it's VERY loud) straining to hear the voice say "fire" or "carbon monoxide"? Or are you just going to get out of the house? The alarm is going off for crying out loud! A fire should be readily apparent. If it's CO you don't want to be in the house anyway. I hope this style is still around in 10 years when I need to replace this one! ... show more

    • Not Hard Wired! also Great Choice!
Size: 1 Pack Style: Previous Model Pattern Name: Detector
I have several smoke alarms that are wired together, when the battery fails on one I cannot tell which one is faulty as they all go off. It drives me nuts. To avoid this I'm going with not wired and having a CO detector is a plus. (These are not returnable so I hope they work OK in the long term). The optimum position for these is halfway up the wall, as a compromise between CO -ground and Smoke -ceiling. In practice I am putting them on the ceiling like the old ones though . Lower down it's too easy for kids to mess around with them. Pros -Easy to hear the problem (fire or CO2) and self test to make sure it's working. The noise of this self test isn't too bad unlike the old style alarms. -Easy to put in the batteries , after the first few attempts. -Snaps into the ceiling ring easily. -Not hard wired together, the alarms are all separate. Cons -The old ceiling ring won't fit if it's a different brand, put the new ring in place the holes pattern is similar.. ... show more

    • Good quality
Size: 1 Pack Style: Previous Model Pattern Name: Detector
Very pleased with these as they detect smoke & carbon monoxide. I have had the one in my kitchen go off several times because of smoke from me cooking. It's loud & continues on until it's turned off. So, I know if it's ever a fire in my house the loud alarm will alert me.

    • Easy to install
Size: 1 Pack Style: Previous Model Pattern Name: Detector
Works well maybe to well. Cooking toast on light setting activated it. But rather deal with it going off and having to take it down while cooking and know it will work while sleeping

    • Voice Activation saved my life! Get as a gift to your loved ones! You may save their life too!!
Size: 1 Pack Style: Previous Model Pattern Name: Detector
Tested just fine. Hopefully we will never know how good it works. Just came back from staying at my mom's house in Florida. Never mind about the hurricane. The Generator was emitting fumes into the roofline, and her awesome "voice alarm" alerted us to carbon monoxide in the house at about 5:30 in the morning. The house was not that old, therefore, now were the alarms. Take them seriously!! We called the fire dept. right away and they immediately told us to get out of the house. A few minutes later, the firemen showed up with tanks and masks on. Did a test before they stepped all the way into the house. YES! WE had carbon monoxide at the Dangerous level in the house. Praise God for the voice alert that screams out "Carbon Monoxide". The firemen cleared the house out by opening windows, turning of the generator/gas, and setting up fans. We waited outside for them to give us the all clear. They told us that we were the 5th house that evening. When I came home, I immediately ordered not 1 but 5 of these. I am giving them as early Christmas presents. It is a gift that may possibly save their lives!! Totally love that they came up with the voice activation because the one I had in the past was old and cried wolf way too many times. It would go off all the time when I lit a candle or sprayed perfume. ... show more

    • So easy to install and dual function!
Size: 1 Pack Style: Previous Model Pattern Name: Detector
Taking down my old smoke detector to change the battery, I noticed it was very close to its expiration date and felt a little daunted when I went to look for a replacement. Soon figured that one that doubles as a smoke detector/ carbon monoxide detector was the way to go. This one was a good price and had good reviews. It was very easy to install. It's loud enough that I run from the room and wince whenever I test it, but loud in an alarm is certainly nothing to complain about. The alarm message is sustained and worded clearly. It's less than a year since I bought and installed it, but nothing in its performance when I test it indicates any loss in power. ... show more
