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).

The Kidde alarms work great! Unfortunately I needed the hardwired version. Globalsupply1 has been great to work with for the return of my items. I would recommend anyone who needs Kidde detectors to use Globalsupply1 for your purchase.

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

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.

  • 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
