• 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 a
maximum 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 standards, 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 STORAGE OR UNOCCUPIED, AND AT LEAST ONCE A WEEK DURING USE.
