Amazon.com Product Description
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.

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 (CO) 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 the pattern until smoke is eliminated. View movie showing voice warning
Carbon Monoxide: Four short alarm beeps followed by a verbal warning "Warning! Carbon Monoxide!" This continues until the unit is reset or the CO is eliminated. View movie showing voice warning
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 and will be accompanied by the chirp sound. The "Low Battery" warning will only sound once every fifteen minutes.
Voice Hush Indication: "Hush Activated" and "Hush Canceled" 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.
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 10 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 Battery Power, Indicator LED, Test Feature and Low-Battery Warning
The battery powered alarm 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.
Seven (7) 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 5-year limited warranty.

The talking alarm arrived in excellent condition and right on time. I admire this item as it shouts FIRE AND OR SMOKE. You ought to try it.

I purchased this as a replacement. I had a very good experience with the old one so I wanted the same kind & model. Your time table for us receiving it was surpassed and it arrived about 3 days before we were told it would arrive. This was a very good experience.

Thankfully I've not needed. With gas heat, just didn't want to take a chance of NOT waking up one morning, as I understand you are asleep before anyone uncovers a leak. Prevention is always best practice!

Two times in the last year I had potentially life-threatening fires. My house was full of smoke and my old detector didn't go off. Fortunately I was awake both times and dealt with the problems promptly with no loss of life or fire damage.
After the second time my old detector didn't alert me; I had to take action. The Kidde seemed like a good choice because it has several features I like:
* Hard-wired with battery backup.
* It sets of the other smoke detectors in the event of a fire or CO problem.
* Ionizing smoke detector is state-of-the-art.
* It talks and beeps.
* It uses inexpensive AA Batteries
For the life of me, I can't understand why the local building code only requires one smoke detector on the first floor so I bought this as added protection. I also bought a KN-COB-IC, Kidde 120V Hardwired Nighthawk Interconnectable Carbon Monoxide Alarm with Battery Backup to replace the defective smoke detector. My review for that product is pretty-much the same except it uses an expensive 9V battery instead of the AA batteries this one uses.

Purchased three of these a week ago to replace old smoke-only alarm w/9-volt battery. The AA-battery is a big plus, since this size is almost universal in electronic devices. Installation was easy, however, there was a discrepancy on which screw holes to use for mounting, but this was rectified with a call to customer service.(Mount as shown on p. #15 of instruction book.) Also, you do NOT have to use tamper-resistant feature to install. (This option is for use in public areas, access by children etc.) Product-life is two (2) years greater than comparable First Alert model & it has an LED light showing it's "working properly" [not available on First Alert.]
If you're a NY State resident, it is now a law that homes w/fuel-burning furnaces etc. must have a CO alarm. This combo alarm is the answer.
