Kidde KN-COSM-B Reviews
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.

* Test Reset Button tests alarm circuitry and triggers the voice announcement
* UL Approved
The Kidde KN-COSM-B Battery-Operated Carbon Monoxide and Smoke Alarm combines two important safety devices into 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 uses three AA batteries, protecting you and your family even during a power outage.
This alarm uses ionization sensing technology for the smoke alarm. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Kidde strongly recommends that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fire that can occur within the home.
