IN THIS AREA
1. Where combustion particles are produced. Combustion
particles form when something burns. Avoid installing in the
areas include poorly ventilated kitchens, garages, and furnace
rooms. Keep units at least 6m from the sources of combustion
particles(stove,furnace,water heater, space heater)if possible.
Ventilate these areas as much as possible.
2. In air streams near kitchens. Air currents can draw cooking
smoke into the sensing chamber of a smoke alarm near the
kitchen.
3. In very damp, humid or steamy areas, or directly near
bathrooms whith showers. Keep units at least 3m away from
showers saunas, dishwhashers, etc.

4. Where the temperatures are regularly below 40 F(4 C)or
o
above 100F(38 C),including unheated buildings, outdoor rooms,
porches, or unfinished attics or basements.
5. In very dusty, dirty, or greasy areas. Don’t install a smoke
alarm directly over the stove or range. Clean a laundry room
unit frequently to keep it free of dust or lint.
6. Near fresh air vents, ceiling fans, or in very drafty areas.
Drafts can blow smoke away from the unit, preventing it from
reaching the sensing chamber.
7. In insect infested areas. Insects can clog openings to the
sensing chamber and cause unwanted alarms.
8. Less than 305ram away from fluorescent lights. Electrical
“noise” can interfere with the sensor.
9. In “dead air” space, for example, in Diagram 1,near the
corner less than 10cm.
10. If you have a smoking meeting room, don’t install the alarm
there for the unit will alarm when several persons smoke;
Tools you will need:
* Pencil

into 35mm deep.
5. Insert the plastic screw anchors into the holes and tap them
gently with a hammer. Tighten the 3*30 screws into the screw
anchors, then loosen them two turns.
6. Slide the smoke alarm base up to the screw heads end up in
the narrow ends of the mounting slots, then tighten the screws
