• For mobile home installation, select locations carefully to avoid thermal barriers that may form at
the ceiling. For more details, see MOBILE HOME INSTALLATION section.
• When mounting the alarm on the wall, use an inside wall with the top edge of the alarm at a maxi-
mum of 12" (30.5 cm) below the ceiling.
• Put smoke alarms at both ends of a bedroom hallway or large room if the hallway or room is more
than 30 feet (9.1 m) long.
• Install Smoke Alarms on sloped, peaked or cathedral ceilings at or within 3ft (0.9m) of the highest
point (measured horizontally).
This equipment should be installed in accordance with the National Fire Protection Association's 72
(National Fire Protection Association, Batterymarch Park, Quincy, MA 02269).
Mobile Home Installation
Modern mobile homes have been designed and built to be energy efficient. Install smoke alarms as
recommended above. In older mobile homes that are not well insulated compared to present stan-
dards, extreme heat or cold can be transferred from the outside to the inside through poorly insulated
walls and roof. This may create a thermal barrier which can prevent the smoke from reaching an alarm
mounted on the ceiling. In such units, install the smoke alarm on an inside wall with the top edge of the
alarm a maximum of 12" (30.5 cm) below the ceiling.
If you are not sure about the insulation in your mobile home, or if you notice that the outer walls and
ceiling are either hot or cold compared to the room air temperature, install the alarm on an inside wall.
NFPA 72 (National Fire Protection Association) requires smoke alarms be installed in each sleeping
area.
WARNING: TEST YOUR ALARM OPERATION AFTER MOBILE HOME HAS BEEN IN STOR-
AGE OR UNOCCUPIED, AND AT LEAST ONCE A WEEK DURING USE.
