Mobile Home Installation - Kidde 910 User Manual

• When mounting an alarm on the ceiling, locate it at a minimum of 4" (10 cm)
from the side wall. (see Figure 1).
• When mounting the alarm on the wall, use 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).
• 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). NFPA 72 states: "Smoke alarms in
rooms with ceiling slopes greater than 1 foot in 8 feet (.3m in 2.4 m) horizontally
shall be located on the high side of the room." NFPA 72 states: "A row of detec-
tors shall be spaced and located within 3 ft (0.9m) of the peak of the ceiling meas-
ured horizontally" (see Figure 3).

MOBILE HOME INSTALLATION

Mobile homes built in the past five to seven years have been designed to be energy
efficient. Install smoke alarms as recommended above (see Figure 1).
In 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 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. For
minimum protection, install at least one alarm close to the bedrooms. For additional
protection, see SINGLE FLOOR PLAN in Figure 2.
