Sometimes a fire can smolder for hours before erupting into flames. Photoelectric Sensing Technology is more sensitive than Ionization Sensing Technology at detecting these sorts of smoldering fires, like those caused by cigarettes burning in couches or bedding.
Other fires erupt into flames quickly, like kitchen grease fires or fires fueled by paper burning in a wastebasket. Ionization Sensing Technology is generally more sensitive than Photoelectric Sensing Technology at detecting these sorts of flaming fires.
Loud Alarm and Reliable Construction for Peace of Mind
The loud, 85 dB alarm gets your attention quickly, so you can get out quickly or contain a minor fire before it spreads. Plus the smart dual sensor helps the detector recognize the difference between non-threatening conditions and real emergencies, so false alarms are minimized.
This smoke detector meets the UL 217 standard for dual-sensor home smoke detectors, which means that it has passed tough quality-assurance tests and can be depended on to offer reliable protection.
Remote Mute and Easy Battery Access for Safety and Convenience
To mute unnecessary alarms instantly, you can simply point almost any household remote control at the detector and click mute--whether the remote is for your TV, stereo, DVD player, or another appliance. The convenience of this feature means that something as simple as burnt toast never tempts you to take the battery out of your smoke detector and create an unsafe situation in your home. The mute button can also be used to test the alarm function, helping you ensure that your home and family are always protected.
This smoke detector is powered by a standard 9V battery (included). And, because a smoke detector is only effective if it is properly maintained, you'll appreciate that the EZ access battery door means there's no need to remove the alarm from your ceiling when it's time to change the battery.
This smoke detector's neutral, white finish blends in with your décor, and the unit measures just 5.7 x 5.7 x 2.8 inches. It is backed by a limited 10 year warranty.

Kidde KN-COSM-B Battery-Operated Combination Carbon Monoxide and Smoke Alarm with Talking Alarm Review

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.

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.

First Alert CO615 Carbon Monoxide Plug-In Alarm with Battery Backup and Digital Display Review

The First Alert CO615 carbon monoxide alarm uses an electrochemical carbon monoxide sensor-the most accurate technology available. Installation is as simple as plugging it in to any wall outlet. Its easy-to-read backlit digital LED display gives you a clear read-out of current CO concentrations in parts per million. The alarm includes a battery back-up giving you peace of mind in a power outage. The test/silence button both silences a non-threatening alarm or low battery warning and allows you to test the unit's functionality. The unit monitors and re-alarms if carbon monoxide levels persist sounding a loud 85-decibel horn. An audible and visual low battery signal alerts you to replace the battery and an indicator alerts you when a battery has been removed. An end-of-life alarm of three chirps alerts you to replace the unit. Two AA batteries are included. 5-year limited warranty. UL listed. --Bree Norlander
