IF YOUR HOUSEHOLD OR RESIDENCE HAS SEVERAL FLOORS,
THERE MUST BE AN ALARM ON EVERY FLOOR, INCLUDING IN THE
BASEMENT. See Figure 3.
• Do install a smoke alarm in every bed-
room where a smoker sleeps.
• Do install a smoke alarm in every room
and bedroom where electric appliances
(such as portable heaters, humidifiers or
electric blankets) may be operated while
someone sleeps.
• Do install a smoke alarm inside every
bedroom where someone sleeps with
the door closed. Smoke can be blocked
by the closed door, or the alarm may not
wake the sleeper if the door is closed.
• Do install smoke alarms at both ends of a bedroom hallway if it is more
than 30 feet long.
• Do install basement smoke alarms at the bottom of the basement
stairwell.
• Do install second floor smoke alarms at the top of the first-to-second
floor stairwell, as long as no door or obstruction blocks the path of the
smoke to the alarm.
• Do install a smoke alarm in a room where flammable household
chemicals or solvents are stored. For example, if you keep kerosene,
paint thinner or certain types of contact cements within your residence,
install a smoke alarm in that room, unless not recommended by a situa-
tion described in the section WHERE YOU SHOULD NOT INSTALL
SMOKE ALARMS.
• Do install smoke alarms on the ceiling not closer than 4 inches to any
wall or corner, or on the wall at least 4 inches but no more than 12
inches from the ceiling. See Figure 4.
• If your ceiling has radiant heat or has a lack of insulation to the outside,
ceiling mounting of your smoke alarm is not advisable due to tempera-
ture variations. You should follow the wall-mounting procedures.
• If you have a peaked, sloped, gabled or cathedral-style ceiling, mount
your smoke alarm 4 to 36 inches (3 feet) MEASURED HORIZONTALLY
FROM THE HIGHEST POINT ON THE CEILING, as shown in Figure 4.
