About This Product

Intelligent combination alarm offers you and your family protection from fire and carbon monoxide. The intelligent combination alarm uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you and your family from carbon monoxide. Voice warning alerts you to the type of danger present. The Intelligent Alarm combines the detection capabilities of an ionization smoke sensor - which is more likely to detect smaller, less visible fire particles, like those produced by flaming fires - with that of an electro-chemical sensor, which is used to detect CO. 10-Year Warranty.

          A must for every home.
          This smoke and carbon monoxide detector with voice alarm takes the guess work out of determining what type of danger is eminent. Along with its high pitched beep, the voice will alert you to what type of emergency is occurring. The device has batteries already installed and this just gives me a more peaceful state of mind that my family will be able to get out of the house in the event if fire or carbon monoxide exposure.

          Good combination!
          I am very happy with the Kidde Combination Smoke and Carbon Monoxide Detector. It came complete with mounting hardware and batteries. This eliminates one more chore that must be remembered and performed annually. Instead of two items to check and change batteries in, now there is only one item. I really like that it is powered by 2 AA batteries. They are easier to change and more readily available, not to mention cheaper than 9 Volt batteries. It comes with very detailed instructions on properly locating the detector. Takes less than 5 minutes to install and the test button is easy to identify. The alarm is loud enough to get your attention without being painful. It is recommended to test weekly.

          Great Detector.
          This Kidde - FireX Smoke & Carbon Monoxide Detector is a great warning system. It has different distinct audio alarm sounds for smoke or carbon monoxide detection and the voice alert tells which danger. It also warns you of low batteries and has a self-testing component and a manual test button. It is powered by 2-AA batteries which are included. Installation was easy. The mounting bracket attaches to the wall or ceiling and the alarm turns onto the bracket. This allows for easy removal to replace the batteries. This is a great detector for in-home or garage use.

          These detectors are easy to install and effective. I inadvertently tested one right away when I started using a stove burner which had some oil residue on it. Even though it didn't seem like it was producing much smoke and was 10-15' away, it triggered the alarm.

          Fit the older wall attachments, so the change over was simple. The one in the kitchen has gone off only once; while I was cooking at a high temperature. So they seem to work well.

          i replaced older smoke detectors with smoke and CO detectors. Comes with long lasting batteries. Installed on ceiling with double sided tape (not included). I had to move the one in the kitchen away from the stove area as it was too sensitive. No adjustment for that. A good product.
