Carbon Monoxide Detectors
CO poisoning is completely preventable with a trusted carbon monoxide alarm.
Help protect your family with a Kidde carbon monoxide detector. An odorless, poisonous gas that can easily build up in your home without your knowledge, carbon monoxide sends more than 50,000 people a year to the hospital and kills hundreds. Installing a reliable CO detector in your home is one of the best ways to give your family the warning they need to help prevent CO poisoning. Whether you choose a battery-powered carbon monoxide alarm, a plug-in model, or a hardwired CO alarm, install a detector on each level of your home and near any potential sources of CO gas, such as furnaces, water heaters, or fireplaces.

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
