Combination Smoke/Carbon Monoxide Alarms
Get two times the protection from one reliable alarm.
Carbon monoxide and fire can make for a deadly duo, but Kidde makes it easier to protect yourself against both. Combination smoke and carbon monoxide alarms have sensing technologies that work together to detect fires and the odorless, colorless, tasteless gas known as CO – the silent killer. Each combination alarm includes the company’s patented Nighthawk™ electrochemical CO sensor.

Power Source
info
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

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

10-Year Battery Powered- Combination CO/Smoke Alarms
Combination alarms offer protection from two deadly threats in one unit. Combo alarms can save space, and you'll only need to change and test batteries in one device rather than two. 10-year sealed battery alarms offer a variety of benefits to the millions of Americans who rely on continuous battery-powered smoke and carbon monoxide detection in their homes. The alarms are powered by sealed, long-life lithium batteries for 10 years (the life of the alarm), meaning they are always on.
