Amazon.com Product Description

Offering breakthrough technology to provide maximum protection for your family, the Kidde KN-COSM-XTR-B intelligent alarm combines fire, smoke, and carbon monoxide (CO) alarms into a single device. And more than just beeping alerts, the KN-COSM-XTR-B provides voice warnings that clearly state the present danger-- announcing either "Fire! Fire!" or "Warning! Carbon Monoxide!" And if you don't currently have a CO detector, it's never been a better time to add one as an increasing number of state and local governments are passing legislation that will require one in your home.

Kidde KN-COSM-XTR-BIntelligent AlarmAt a Glance:

• Combined carbon monoxide and smoke alarm

• Voice alarm announces hazard type (either "Fire! Fire!" or "Warning! Carbon monoxide!")

• Two flashing LEDs--green for normal operation, red for alarm

• Powered by three AA batteries

• Seven-year limited warranty

Features

The KN-COSM-XTR-B intelligent alarm offers a fast response to real fires, including smoldering and fast-flaming, as well as protects you from carbon monoxide. 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 those of an electrochemical sensor, which is used to detect CO. Since carbon monoxide is present in all fires, having both detection chambers work together is ideal.

When either sensor notices a potential hazard, it communicates with the other. Depending on what is detected, the alarm adjusts its smoke sensitivity in order to better discriminate between a real hazard and a false one. If fire is detected, a red LED flashes while three long beeps are sounded, followed by a verbal warning message of "Fire! Fire!" If carbon monoxide is detected, four short alarm beeps sound, followed by a voice alert of "Warning! Carbon monoxide!"

Other features include a low-battery warning, a hush feature that silences nuisance alarms, a test/reset button, and a peak CO level memory. It's powered by three AA batteries, and it's backed by a seven-year limited warranty.

From the Manufacturer

The Kidde KN-COSM-XTR-B 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.

Technical Details

• Voice alarm, announces hazard type detected helping to speed up correct reaction to hazard detected
• Combined carbon monoxide and smoke alarm, single unit can be installed instead of two, reducing installation time
• Test reset button tests alarm circuitry and triggers voice announcement, flashing green and flashing red LEDs
• Low battery condition announcement initiates alarm chirp and flashing red LED activation
• Battery powered, provides protection even during power outages

Costumer Reviews

This review is from: Kidde KN-COSM-B Battery-Operated Combination Carbon Monoxide and Smoke Alarm with Talking Alarm (Tools ; Hardware)

I've installed installed two of these Kidde brand combination smoke and carbon monoxide detectors in my elder parents home. I have one in my own home as well and have found them all to be reliable and trouble free.

What attracted me to this model were its many features:

First, it has a low profile, attractive and unobtrusive design.

Second and perhaps most important, it has a voice speaking function that, in addition to the 85db alert horn, will speak out clear warnings: "FIRE, FIRE" or "DANGER: CARBON MONOXIDE". I think that this feature is a terrific addition toward modern life-safety technology. Indeed, you will likely see more voice warning devices in the near future.

We rely on these detectors to warn us, especially at night when we are sleeping. Awakening to this detector from a deep sleep helps orient you quickly by telling you the specific danger -- clearly and unmistakably. Notably, recent studies have shown that children can sleep through traditional smoke detector alarms, but will respond to voice warnings -- which this unit provides. Thus, placed in or near bedrooms this device can be a true lifesaver.

Another favorite feature is ease of installation. It was a breeze and truly could not be simpler. A screwriver is all you need. A small power drill/driver would speed the process, but is not necessary. Two screws into the ceiling or wall and you are done with the mounting bracket. The detector then just clicks in to place with a clockwise flick of the wrist. This is a do-it-yourselfer's dream. It doesn't get any easier!

Battery maintenance is easy too as all you need do is turn the detector counter-clock wise a few clicks, and down it comes. You slide open the battery cover, take out the old batteries and pop in the new. Replace the detector back in the attached ceiling bracket, give it a slight turn and in it goes with a firm click. Done! Easier than screwing in a light bulb.

Finally, the price is right! Under $40 for a unique life-safety device that is quickly installed and easily maintained.

I have elected to use Energizer lithium batteries and replace them every 12 months -- with no problems. You may wish to change the batteries every 6 or 9 months. Duracells would also be a good choice. I personally would not use the cheaper, so called "heavy duty" batteries in a life-safety device.

I should add that I would also suggest that if you have a home with multiple levels or an apartment with several rooms, having a separate stand-alone carbon monoxide detector elsewhere in the house as part of a total home plan would be a wise investment. Kidde also makes a fine combination model that protects against Carbon Monoxide and Explosive Gas. That unit, which has a digital display, runs on electricity and has a battery back-up system. It plugs in any electric outlet and can stay in the wall socket, or it can be placed flat on a table or dresser.

I would also recommend Kidde's dedicated dual sensor photoelectric/ionization smoke detectors. These dual sensor devices provide maximum warning under fast or slow moving fire conditions. As one never knows what kind of fire could occur, these are the most versatile.

Be sure to test your alarm regularly. REMEMBER that most carbon monoxide detectors NEED TO BE REPLACED about every five to seven years (see manufacturer's guidelines). Similarly, smoke detectors have a useable life span as well. It's usually a little longer than carbon monoxide detectors -- check your manufacturer's guidelines.

The Kidde KN-COSM-XTR-B Intelligent Alarm, Combination Carbon Monoxide, Fire and Smoke detector is replacing a very similar Kidde alarm that finally died after several years of faithful service.

I looked at "First Alert" alarms as I have heard good things about them years ago (30 years ago), but after reading the reviews on First Alert alarms it became obvious that things have changed and there seemed to be some problems now with them. Apparently they are malfunctioning in a number of ways.

So I stuck with Kidde as it had served me well in the past, and purchased one very similar to the outgoing Kidde. The nice thing about doing that is that the new one fits on the old mount. All I had to do was put the batteries (included) in the new one and twist it onto the old mount and then enjoy the rest of my day! Life is good!
