of alarms shall be spaced and located
within 3 ft (0.9m) of the peak of the

MOBILE HOME INSTALLATION
Modern mobile homes have been
FIGURE 3
designed and built to be energy effi-
cient. Install heat alarms as recom-
mended above (refer to RECOMMENDED LOCATIONS and FIGURE 1).
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 heat from reaching an alarm mounted on the ceiling. In
such units, install the heat alarm on an inside wall with the top edge of the
alarm at a minimum of 4" (10 cm) and a maximum of 12" (30.5 cm) below the
ceiling (see figure 1).
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, install the alarm on an
inside wall.
WARNING: TEST YOUR HEAT ALARM OPERATION AFTER RV OR MOBILE
HOME VEHICLE HAS BEEN IN STORAGE, BEFORE EACH TRIP AND AT
LEAST ONCE A WEEK DURING USE.
