KIDDE-KN-COSM-IBA
Protects from two different hazards, smoke and carbon monoxide (view larger).

The KN-COSM-IBA combines a Carbon Monoxide and Ionization Smoke Alarm, providing two important safety devices in a single unit. This alarm includes a voice warning system that helps eliminate confusion, as it tells you if its detected fire or carbon monoxide, or even if it needs a new battery. This alarm has 2 AA battery backup, which protects you and your family — even during a power outage when many incidences occur. The alarm also allows you to easily silence nuisance alarms using its convenient Smart Hush feature.

This talking combo alarm is powered by your home's electricity and can interconnect with other smoke alarms in your home. Experts recommend interconnected alarms, because when one sounds, they all sound, providing an early warning against fire by dramatically increasing your ability to hear an alarm anywhere in your home, regardless of where the fire starts.

Interconnected-House
Provides the recommended protection of an interconnected system. When one alarm goes off, they all do (view larger).

Combination Smoke/CO Alarm for Improved Safety

The Kidde Combination Carbon Monoxide & Smoke Alarm includes a voice warning system that eliminates confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery is in need of replacement or your alarm is in hush mode.

Alarm Warnings

Fire: The red LED will flash and be accompanied by three long alarm beeps followed by a verbal warning message "Fire! Fire!" The alarm will repeat pattern until smoke is eliminated.

Carbon Monoxide: Four short alarm beeps followed by a verbal warning "Warning! Carbon Monoxide!" This continues until the unit is reset or CO is eliminated.

Low Battery: One chirp followed by warning "Low Battery" The red LED light will flash. This pattern will continue every minute for the first hour. After the first hour the red LED light will flash once every minute accompanied by the chirp sound. The low battery warning will only sound once every fifteen minutes.

Voice Hush Indication: "Hush Activated" and "Hush Cancelled" voice announcement.

Peak Level Memory: If the alarm had detected a CO level of 100ppm or higher when the Test/Reset button is pressed, the unit will announce "Carbon Monoxide Previously Detected" to warn of the CO incident.

Inter-connectable for Improved Safety

Fire and consumer experts recommend interconnected alarms for added protection. According to the National Fire Protection Association (NFPA), most Americans feel they are more at risk of being a victim of a tornado than of a house fire. Actually the opposite is true. Fires are more common than any other disaster that strikes a family at home, and can become deadly in minutes.

You have on average less than three minutes from the time you hear a smoke alarm to escape a fire. The sooner you hear an alarm, the sooner you can get out safely. Smoke alarms that link together so that when one goes off, they all go off, are called interconnected alarms. These alarms provide more warnings in more places, giving your family more time to escape a house fire. Houses built after 1993 are required by building codes to have interconnected alarms that are wired into their electrical system.

KN-COSM-IBA Hardwire Combination Carbon Monoxide and Smoke Alarm

At a Glance
  • Talking alarm announces the hazard type detected, helping to speed up reaction time
  • Employs both smoke and carbon monoxide sensors
  • Inter-connectable to provide improved protection
  • Features a hush button to silence the alarm for non-emergency situations like a smoky dinner
  • Battery safeguard ensures the unit cannot be accidentally mounted without batteries

Trademarked Hush Feature for Convenience

By pressing the Hush button, you can easily and safely silence nuisance alarms caused by non-emergency situations, such as overcooked dinners.

This feature desensitizes the alarm for approximately ten minutes. If the smoke is not too dense, the alarm will silence immediately, the unit will verbally announce "Hush Mode Activated," and the green LED will flash every 2 seconds for approximately 10 minutes.

Reliable AA Battery Backup, Indicator LED, Test Feature, Low Battery and End-of-Life Warning

The alarm's AA battery backup provides continuous protection, even during power outages. Because this alarm only helps protect you if it's working, this unit features a red LED that flashes every 30 to 40 seconds to indicate that it is operating correctly. For additional peace of mind, the alarm also contains a test/reset button that enables you to periodically test its circuitry and horn.

If any form of battery failure is detected the red LED light will flash and the unit will "chirp" one time, followed by the warning message "Low Battery." This cycle will occur once every minute, and will continue for at least seven days.

Ten years after initial 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. UL 2034, the independent standard applicable to CO alarms, requires CO alarms to have an end of life warning. This requirement went into effect in March 2007, meaning any CO alarm manufactured after April 2007 with a UL listing must have this feature. Most states that require CO alarms in residential dwellings mandate that the alarm meet the UL 2034 standard.

The unit measures just 5.75 inches in diameter and 1.7 inches deep, and it features a neutral, white finish. It includes tamper resist features to deter vandalism or theft. This combination smoke/CO alarm is UL listed, so you can be confident of its quality, and it is backed by a 10-year limited warranty.

From the Manufacturer

The leading cause of accidental poisoning deaths in North America, Carbon Monoxide is odorless, tasteless and invisible. It is a silent killer. Kidde CO alarms include the most accurate sensing technology available, the patented Nighthawk electrochemical sensor. This unit combines a Carbon Monoxide and Ionization Smoke Alarm, providing two important safety devices in a single unit. This alarm includes a voice warning system that announces "Fire, Carbon Monoxide, Low Battery or Smart Hush Activation." The voice alarm eliminates any confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery is in need of replacement. This unit is hardwired and will work with many interconnected systems. This combination alarm has battery backup, protecting you and your family even during a power outage when many incidences occur. Install at least one CO alarm on every floor and in sleeping areas. Make sure CO and Smoke alarms are at least 15 feet away from cooking or heating appliances to prevent false alarms. Replace CO alarms every 5 to 7 years to benefit from the latest technology upgrades. Ionization sensing alarms may detect invisible fire particles associated with fast flaming fires sooner than Photoelectric alarms. Studies show both types will effectively detect either type of fire. For optimal protection, install both smoke alarm technologies in your home.

For those concerned about previous mfr date issues with reviews, my units were manufactured within 45 days of my purchase date -- which is actually extremely reasonable. I'm guessing that wherever these are manufactured, they are taking a boat trip at least once before hitting a warehouse to wait for me to purchase.

I recently replaced my 10 year old BRK detectors around my entire house. I installed the Kidde PI2000 dual sensor detector in each beadroom and a Kidde KN-COSM-IB smoke and carbon dioxide detector in the hallways in the basement, first and second floor hallways.

I researched first alert, brk, and kidde, mostly because I could see them at my local big box hardware store. I chose Kidde becuase it had more features for the wired-in detectors than both first alert and brk. First alert appears to have focused their current lines on battery only units and wireless communications. Brk also had limited options in dual sensors or combo CO detectors in a wired setting. Since neither first alert or brk could supply both a photo sensor/ion wired unit AND a dual CO and smoke wired detector that communicated together, I chose kidde detectors. I wanted them all to communicate and mixing and matching product vendors makes communications between the units impossible.

There are no pretty dual detectors that exist on the market. These are nice and boring and don't draw attention. They have a working hush button. That's a new feature that I appreciate. I haven't ripped one of these off the ceiling once yet to get them to stop their alarms.

I've never done a smoke or CO test. I'll let the experts run those tests. My only tests are using the test button. But it works as identified and is loud.

Product Packaging: Standard Packaging
Purchased five of these for use in our personal home with the intent to buy more for rentals if they performed well. Really liked the idea of having a voice warning that tells what the problem is and was thrilled at how easy the installation was...for about 48 hours.

About two days after initially installation, started getting a "beep" but no voice indication of low battery/other. We always keep spare batteries in stock so decided to replace the batteries with fresh ones and problem seemed to go away. Temporarily.

A few days later the alert goes off again which of course, signals ALL of them to go off as they are interconnected. This time it indicates a dead battery. Odd since we replaced them but figured our batteries may have been older than we realized. Went to the store and bought all new batteries - replaced in all five units.

A few nights later - about 2 in the morning - we get a full fledged alert with the 'WARNING -FIRE!" screeching through the house. After peeling ourselves off the ceiling, we took down the one main culprit and figured that one may be a lemon. Since we have five in the house, we still felt it may be an isolated problem...EXCEPT

The Next night we get yet another screeching alert...."WARNING - Carbon Monoxide". It should be worth mentioning to note that we had NO fireplace burning and do NOT cook or heat with anything other than electricity. In fact, nothing was running whatsoever.

At this point, we're exhausted from several nights of interrupted sleep and all of these are going back. The good news is the interconnected portion works. The bad news is the constant false alarms will leave you likely to take them down in order to get a full nights sleep.

In all our years of smoke alarms these have given more false alerts in just a couple weeks than the past 20 years combined. SKIP~!

I read the reviews and was worried about the A/C problem. I decided to give it a try. I needed to replace my smoke detector for a combo, and the original was an A/C w/ battery backup, so this one fit the bill. I received the first detector and followed all the instructions. I am comfortable doing electrical work around the house and do have experience. The problem I encountered is that the green light on the detector that indicates AC power would turn off after 5 minutes. I checked all the connections and used a tester to verify that the connector that went to the unit had power. Everything was fine, except that the green light would still turn off after 5 minutes and stay off until I unplugged and plugged it in again. This means that the unit is being powered by the battery which would eventually run down. I immediately contacted Kidde through their web site. It has now been a month with no reply from them. I waited a couple of days to hear from Kidde, after which I contacted Amazon for a replacement. Amazon as usual is great and is one the many reasons I keep on buying from them. I received the replacement from Amazon a couple of days later. I installed it and this time the green light remained on. I returned the broken one, and I am a happy customer :-) For those that complained about the battery running down, I would suggest that you check the green that light is on.

Replaced a 10 year old BRK Smoke Detector...This Kidde is Great! Hookup took less than 5 minutes, just replaced old pigtail connector, with the included Kidde connectors. The Kidde base feels more sturdy and the sure-lock twist design guaranteed a perfect fit. The Kids love the "voice" warnings (test mode) for Fire & Carbon Monoxide...I also love the visible 120v power indication (green light). Did I mention that Amazon.com has the best price on this unit...yeah, pick one up!
