Smoke and Carbon Monoxide Detectors

Double your detection with a smoke and carbon monoxide detector from Kidde. 

These combination alarms quickly alert you to both the presence of smoke hazards and dangerous levels of carbon monoxide (CO), a poisonous gas found in many homes. CO is generated by heating and fuel-burning appliances, including fireplaces, water heaters, gas ovens, and generators, and a CO alarm should be installed on every level of your home. A combination smoke and CO detector can alert your family to both dangers, in one discrete, space-saving alarm. Choose from battery powered and hardwired smoke detector and carbon monoxide detector devices, including alarms with voice warnings to alert you to the type of danger being detected. Help protect your family with a Kidde combination smoke and carbon monoxide alarm.

Power Source Smoke alarms are powered by battery or by your home's electrical system. If the smoke alarm is powered by battery, it runs on either a disposable 9-volt battery or a non-replaceable 10-year sealed lithium battery. Alarms that receive their power from your home's electrical system (hardwired alarms) usually have a back-up battery that will need to be replaced once or twice a year.info
Safety Features <p>There are many special features that can help protect you and your home, or make your safety products easier to maintain and operate. Many of these features are not well known by their name, so to learn more about specific features of a model, select it and view its detail page.</p> <br /> 'Best' models include many safety and convenience features. <br /> 'Better' models include a few safety and convenience features. <br /> 'Good' models include basic safety features.info
Sensor There are two types of sensing technology available. 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.info
