User's Manual

• Locate the first alarm in the immediate area of the bedrooms. Try to monitor the exit path as the bedrooms are usually farthest
from the exit. If more than one sleeping area exists, locate additional alarms in each sleeping area.
• Locate additional alarms to monitor any stairway as stairways act like chimneys for smoke and heat.
• Locate at least one alarm on every floor level.
• Locate an alarm in every bedroom.
• Locate an alarm in every room where electrical appliances are operated (i.e. portable heaters or humidifiers).
• Locate an alarm in every room where someone sleeps with the door closed. The closed door may prevent an alarm not located
in that room from waking the sleeper. Kidde recommends the installation of a Sound Module in all rooms where elderly, the
hard of hearing and children sleep.
• Smoke, heat, and combustion products rise to the ceiling and spread horizontally. Mounting the smoke alarm on the ceiling, in
the center of the room, places it closest to all points in the room. Ceiling mounting is preferred in ordinary residential
construction.
• For mobile home installation, select locations carefully to avoid thermal barriers that may form at the ceiling. For more details,
see MOBILE HOME INSTALLATION below.
• When mounting an alarm on the ceiling, locate it at a minimum of 4” (10 cm) from the sidewall (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 detectors shall be spaced and located
within 3 ft (0.9m) of the peak of the ceiling measured horizontally” (see Figure 3).
MOBILE HOME INSTALLATION
Modern mobile homes have been designed and built to be energy efficient. Install smoke alarms as recommended above, refer to
RECOMMENDED LOCATIONS and Figure 1. 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 that 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.
WARNING: TEST YOUR SMOKE ALARM OPERATION AFTER R.V. OR MOBILE HOME VEHICLE HAS BEEN IN
STORAGE, BEFORE EACH TRIP AND AT LEAST ONCE A WEEK DURING USE.
