Smoke Alarms:  The Fire Department recommends that you install dual sensing smoke alarms.  The package will indicate the alarm is both a photoelectric and ionization type. 

How Many Smoke Alarms Do You Need?
Install smoke alarms on every floor of your home, outside each separate sleeping area, and inside all sleeping rooms. It is recommended that alarms be wired together so when one sounds, they all sound.

On floors without bedrooms, install alarms near the stairway leading to the floor above, in or near dens, living rooms, family rooms, and other living areas.

Don't install alarms in kitchens, bathrooms, or garages (where nuisance alarms go off routinely).

Where Should You Mount Smoke Alarms?
Smoke rises - Mount alarms high on a wall or on the ceiling and bear in mind the following guidelines:
  • Wall mounting: Position the top of the alarm 4 to 12 inches (10 to 30 cm) from the ceiling (smoke alarm must be listed for this application)
  • Ceiling mounting: Position alarms at least 4 inches (10 cm) away from the nearest wall; Position alarms within 3 feet of the door inside the bedroom
  • Pitched ceiling mounting: Mount the alarm at or near the ceiling's highest point
  • In open stairways (no doors at top or bottom): Mount alarm anywhere along the path smoke would travel up the stairs
  • In closed stairways (a door at either end): Mount alarm at the bottom of the stairway
  • Don't mount an alarm near a window, outside door, or forced-air register

Maintaining Your Smoke Alarms
  • Test your smoke alarm monthly
  • Install new batteries when you set the clocks back in the fall
  • Replace any alarm more than 10 years old - Manufacture date can be found inside smoke alarm body
