This smoke alarm uses an extremely small amount of radioactive element in the ionization chamber (see Section 9). Do not try to repair the smoke alarm yourself. Refer to the instructions in Section 12 for service.

1. RECOMMENDED LOCATIONS FOR ALARMS

•Locate the first alarm in the immediate area of the bedrooms. Try to protect 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 protect 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 the alarm from waking the sleeper.

•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 side wall (see Diagram A).

•When mounting the alarm on the wall, use an inside wall with the top edge of the alarm at a mini- mum of 4” (10 cm) and a maximum of 12” (30.5 cm) below the ceiling (see Diagram A).

•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 3 ft. (0.9m) of the highest point (measured horizontally). NFPA states: “Smoke alarms in rooms with ceiling slopes greater than 1 foot in 8 feet (.3 m in 2.4 m) horizontally shall be located on the high side of the room” “A row of detectors shall be spaced and located within 3 ft. (0.9 m) of the peak of the ceiling measured hori- zontally” (see diagram “C”).

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 (refer to RECOMMENDED LOCATIONS and Diagram A).

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 Diagram A).

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 Diagram B.

WARNING: TEST YOUR SMOKE ALARM OPERATION AFTER R.V. OR MOBILE HOME VEHI- CLE HAS BEEN IN STORAGE, BEFORE EACH TRIP AND AT LEAST ONCE A WEEK DURING USE.
