At a minimum, there should be one smoke detector/smoke alarm on every level of your home. Smoke detectors/smoke alarms should be installed on the ceiling, which is where heat and smoke go first during a fire.
Place detectors/alarms as follows:
- First Floor: Place on the ceiling in a main area, near but not in the kitchen.
- Second & Third Floor: Place on the ceiling in hallway between bedrooms.
- Basement: Place on the ceiling in an open area.
Other location notes:
- Consider placing detectors/alarms at least 20 feet from areas of combustion (stove, furnace, water heater, space heaters).
- Consider placing detectors/alarms at least 10 feet from damp, humid or steamy areas (showers, saunas, dishwashers) or directly near bathrooms with showers.
- Avoid where temperatures are regularly below 40F or above 100F.
- Avoid near fresh air vents, ceiling fans or very drafty areas (drafts can blow the smoke away from the detector/alarm).
- Avoid installing closer than 4 inches from the wall or corners.
- Avoid installing closer than 12 inches from fluorescent lights.
It’s recommended that you also install a detector/alarm on the ceiling of each bedroom (near the door).
