How to Install and Test Your Smoke Alarms

The National Fire Protection Association (NFPA) recommends dual-sensor detectors. These combine ionization (which respond best to flaming fires) and photoelectric (which respond best to smoldering fires) capabilities. No matter which detector you choose, look for alarms labeled with an independent, recognized testing laboratory insignia, such as CSA Group Testing and Certification, Inc., NSF International, and Underwriters Laboratories, Inc.

Ideally, you want to have at least one alarm on each floor, depending on the size of your home. Be sure to check local codes as they dictate where you need smoke alarms. Some areas require more than others. This info is available online.

The best location for your smoke detectors will depend on your home’s layout. Here’s a quick guide:

• In the basement — on the ceiling at the bottom of the stairs that lead to the first floor
• In living areas — place high on walls or ceilings
• On the wall — 12 inches or less from the ceiling
• In pitched ceilings — within 3 feet of the ceiling’s peak but not within the apex of the peak

Test your smoke alarms once per month.

A note on alarm replacement: Typically, most new smoke alarms come with 10-year, non-replaceable batteries. Refer to the unit’s instructions for proper battery care or unit replacement as needed.
