## Overview

The Kidde Intelligent Smoke & Carbon Monoxide Detector combines ionization and electrochemical sensors in one battery-powered unit, delivering fast, reliable detection of smoke and carbon monoxide. Featuring clear voice alerts, a smart hush function, and UL certification, it ensures your home stays safe even during power failures, backed by a 10-year warranty.

## Description

Product Description The Kidde Intelligent Smoke & Carbon Monoxide Detector, Battery Powered, Interconnect Combination Smoke & CO Alarm with Voice Alert, model 900-0216, is powered on 2-AA alkaline batteries, to protect during a power failure. Using both ionization & electrochemical sensor technologies, the combination smoke alarm detects smoke & fire, while the carbon monoxide detects poisonous carbon monoxide gas and warns with alarms, LED lights, & voice technology. For CO detection, the alarm will sound with 4 fast beeps and "warning carbon monoxide". For smoke detection, the alarm will sound with 3 beeps with the announcement of "Fire". A red LED will flash in unison with the voice alarm that warns of fire, carbon monoxide, & low battery. The Smart Hush feature silences the fire alarm for approximately 8 minutes. The green LED on the alarm will flash twice per second. UL Certified with a 10-year limited warranty. Meets requirements of UL 2034, UL217, NFPA72, The State of California Fire Marshall, NFPA 101, FHA, & HUD. From the Manufacturer The Kidde KN-COSM-XTR-BA uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protecting you from carbon monoxide and dramatically reducing the chance of nuisance alarms. In addition, this intelligent alarm contains a voice warning that clearly states the present danger, smoke or carbon monoxide, and announces “Fire! Fire!” or “Warning Carbon Monoxide.” It 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 electrochemical sensor, which is used to detect CO. Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. When either sensor notices a potential hazard, it will communicate with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. This constant communication enhances the alarm's overall performance in all fires, and significantly reduces the potential for a nuisance alarm.

Review: Kidde Combination Smoke and Carbon Monoxide Alarm With Voice - Needed to replace the 20+ year old standard First Alert SA67B smoke alarm in my room and wanted something with voice and combo detection as we have a propane fireplace. After struggling to find a battery powered combo unit with voice from Kidde, I finally found this. For $20, this is a great smoke/CO alarm to have in your home. Pros: -Easy to install, comes with the hardware and two new batteries to start out with -Takes 2 AA batteries unlike the more expensive 9 volt, and is easier to remove and replace unlike some of the 9V units;even easier with the front loading battery compartment -Has hush feature, you push the multi-function test/hush button in the middle of the alarm if you set it off accidentally, and the large button makes it easy to to test and silence it. Speaking of the test portion, you just push it instead of having to hold it down unlike most which is good if it is high on a ceiling or wall, so you can easily tap it with a broomstick or something else. Same goes for the hush feature. -Has voice function, which behaves in the following ways: If detecting smoke, unit will emit a loud three long beeps and pause, during which it will say in a fairly hearable female voice "Fire!", then beep another three times, pause with no voice, then repeat. If detecting CO, unit will emit four loud short beeps and pause, saying "Warning, Carbon Monoxide!", beep another four short beeps, pause with no voice, then repeat. If detecting a low or loose battery condition, unit will emit a loud, short "chirp" once a minute, following with "Low Battery!". The voice will only repeat every 15 minutes I believe, so it won't annoy you too much more than a standard unit would. It also features a memory function for detecting previous CO, which means when you come back from vacation or something you can push the button and it will say something like "Carbon Monoxide Previously Detected!". Pushing it again will test the unit, which should be done weekly per the unit itself, but at least monthly at the minimum. Also this alarm features a End Of Life warning chirp, which will behave differently (two chirps instead of one I believe, with no voice prompt). This can be silenced for 3 days up to a month to give you a grace period to but another. So far, I highly recommend this alarm and other Kidde products!
Review: Very good smoke and CO detector - Wired smoke and CO detectors are standard in new construction these days, but for an older house, the battery-powered detectors are still very economical, and they have improved a lot over the years. I just replaced all three of ours with these Kidde detectors, after having a good experience with wired Kidde detectors elsewhere. These have some real advantages. They work even if the house's power goes off. They announce what set off the alarm and even when the batteries are low. Apparently, one thing to know is that you should only use alkaline batteries in these, as the low-battery warning is triggered as the batteries power slowly diminishes over time, so the warning will continue for longer than it would with lithium-ion batteries, which have a very steep decline in power over a short period of time, maybe too short for you to be home to hear the low-battery warning. At any rate, installation was easy, the detectors mounted to the screws that were used with the old smoke detectors, even though they were a different brand. Contrary to what other reviewers mentioned, I had no trouble identifying the positive and negative direction for the two supplied AA batteries (nice not to have to use those expensive 9-volt batteries that other detectors use). You just determine the direction of the batteries (positive and negative symbols are designated in the battery troughs and are visible in good light), press the red plastic no-battery "fingers" down (they both fold in the same direction, even though the batteries point in opposite directions), place the extraction tape in the in the trough, and add one battery, then do the other the same way in the opposite direction. As soon as the second battery is in, you get a beep and a voice command to press the test button. Then the detector goes through its warnings, and ends with a final beep and blink of a green light, indicating that everything is set. I’m not sure why others had trouble getting the batteries in. It just takes a moment of study and a little practice. By the third detector, it was a piece of cake!

## Questions & Answers

**Q: What is the difference between the kn-cosm-xtra-b and kn-cosm-xtra-ba?**
A: The kn-cosm-xtr-b has not been made since 2012. The warranty was 5 years and it had a  7 year life. It took 3 AA batteries.
The kn-cosm-xtr-ba has a 10-year life and warranty. In addition, it uses 2 AA batteries and the battery compartment is now on the front.

**Q: 10 year warranty but co2 requires replacement in 7?**
A: prior to 2013 the sensor had a 7 year life, but that is now 10-years.

**Q: I can't get the battery door to open so that the batteries can be placed in. Any ideas on what to do?**
A: There are red "arms" in the battery compartment that get stuck on the lip of the door is closed without batteries installed. Use an implement to bend the arms back and then slide door open.

**Q: Is this okay to place in the kitchen?**
A: You do not need to place this near the floor. Carbon monoxide spreads evenly throughout a room. It doesn't "fall" as some have suggested. Although as everyone knows, smoke DOES rise, so the ceiling is a fine place to install for both dangers.
