When it comes into your home, it comes into your life.  One home safety device that is often overlooked is the smoke detector. Many people do not notice the importance of this life-saving device.  The U.S. National Fire Protection Agency reports that “having a working smoke alarm cuts the chances of dying in a reported fire in half. Almost two-thirds of home fire deaths resulted from fires in homes with no smoke alarms or no working smoke alarms.”

There are 2 different types of smoke detector systems on the market today:

  1. Smoke detectors that wire a signal to a monitored fire alarm system
  2. And smoke detectors that sense smoke in the air and issue a audible or visual alarm.

Many smoke detectors use both detection methods, sensitive to smoke. Smoke detectors are powered by a central fire alarm system, which uses a battery backup. Many single family homes use smoke alarms powered by a single battery.

Installation and placement

Smoke detectors should be placed where they will do their best job.  Optimal areas include the kitchen, the hallways, attics, bedrooms, and any inhabitable level of the home.  Most state and local laws adhere to the smoke detector location standards established in the National Fire Prevention Association (NFPA 72) fire code.  This code provides up-to-date safety provisions to meet fire detection, signaling, and emergency communications demands. The Code includes requirements for mass notification systems used throughout the country for weather emergencies, terrorist threats, and other threats and emergencies.

Battery Backup

Most home smoke detectors operate on carbon-zinc or 9-volt batteries.  When the battery runs low, the detector will audibly signal at regular intervals.  When it runs out, the smoke detector stops working.

Many new smoke detectors are now sold with a lithium battery.  Lithium batteries are able to last 7 to 10 years.  They reduce the need to replace batteries in your smoke detector.  Yet, by the time they need to be replaced, the smoke detector may also need to be replaced.
