Where to Install
Minimum coverage for smoke alarms, as recommended by the National Fire Protection Association (NFPA), is one smoke alarm on
every level, and in every bedroom (See “Regulatory Information For Smoke Alarms” for details on the NFPA recommendations).
For CO alarms, the National Fire Protection Association (NFPA) recommends that CO alarms be installed on every level
and in the central location outside each bedroom. For added protection, install additional CO alarms in every bedroom.
NOTE: For added protection, install an additional smoke/CO alarm at least 20 feet (6 meters) away from the furnace
or fuel burning heat source where possible. In smaller homes or in manufactured homes where this distance cannot
be maintained, install the alarm as far away as possible from the furnace or other fuel burning source. Installing the
alarm closer than 20 feet (6 meters) will not harm the alarm, but may increase the frequency of unwanted alarms.
In General, Install Combination Smoke and Carbon Monoxide Alarms:
• On every level of your home, including finished attics and basements.
• Inside every bedroom, especially if people sleep with the door partly or completely closed.
• In the hall near every sleeping area. If your home has multiple sleeping areas, install a unit
in each. If a hall is more than 40 feet (12 meters) long, install a unit at each end.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in all rooms, halls, and storage areas, where
temperatures normally remain between 40˚ F and 100˚ F (4.4˚ C and 37.8˚ C).
Recommended Placement
• Ceiling installation only: Place the alarm
as close to the center as possible.
• See Avoiding “Dead Air” Spaces
for more information.
NOTE: For any location, make sure no door
or other obstruction could keep carbon
monoxide or smoke from reaching the alarm.

Where Not to Install
Do Not Place Your Smoke & CO Alarm:
• In garages, furnace rooms, crawl spaces and unfinished attics. Avoid extremely dusty, dirty or greasy areas.
• Where combustion particles are produced. Combustion particles form when something burns. Areas
to avoid include poorly ventilated kitchens, garages, and furnace rooms. Keep units at least 20 feet (6
meters) from the sources of combustion particles (stove, furnace, water heater, space heater) if possible.
In areas where a 20 foot (6 meter) distance is not possible – in modular, mobile, or smaller homes, for
example – it is recommended the smoke alarm be placed as far from these fuel-burning sources as
possible. The placement recommendations are intended to keep these alarms at a reasonable distance
from a fuel-burning source, and thus reduce “unwanted” alarms. Unwanted alarms can occur if a smoke
alarm is placed directly next to a fuel-burning source. Ventilate these areas as much as possible.
• Within 5 feet (1.5 meters) of any cooking appliance. In air streams near kitchens. Air currents
can draw cooking smoke into the smoke sensor and cause unwanted alarms.
• In extremely humid areas. This alarm should be at least 10 feet (3 meters) from a shower, sauna,
humidifier, vaporizer, dishwasher, laundry room, utility room, or other source of high humidity.
• In direct sunlight.
• In turbulent air, near ceiling fans or open windows. Blowing air may prevent CO/smoke from reaching the sensors.
• In areas where temperature is colder than 40˚ F (4.4˚C) or hotter than 100˚ F (37.8˚C). These areas include non
air conditioned crawl spaces, unfinished attics, uninsulated or poorly insulated ceilings, porches, and garages.
• In insect infested areas. Insects can clog the openings to sensing chamber.
• Less than 12 inches (305 mm) away from fluorescent lights. Electrical “noise” can interfere with the sensor.
• In “dead air” spaces. See below for additional information.
• On walls.
