What’s the optimum placement of protection devices in my home?

Early detection of smoke, carbon monoxide, and natural gas is key to saving lives. The National Fire Protection Association (NFPA) recommends installing a smoke alarm on every level of your home, including finished attics and basements. You are also encouraged to install a smoke detector inside every bedroom and at the top of certain stairways.

Do I need four kinds of detectors or can one do it all?

You never know what kind of hazard will strike your home, or when. That’s why we recommend technology that can detect carbon monoxide (CO) and natural gas as well as smoke and fire. You’ll get the most protection from devices that can quickly and accurately detect and respond to a range of threats.

A smoke alarm that goes off when there’s no emergency is annoying. According to the National Fire Protection Association (NFPA), such “nuisance alarms” are the leading reason why homeowners intentionally disable their smoke detectors. Yet doing so can be deadly. A survey conducted by the NFPA found that smoke alarms sounded in only half of the home fires reported to U.S. fire departments, and almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms.
