In very dusty or dirty areas, dirt and dust can build up on the
detector's sensing chamber, to make it over sensitive. Additionally,
dust or dirt can block openings to the sensing chamber and
keep the detector near fresh air vents or very drafty areas like air
conditioners, heaters or fans, fresh air vents and drafts can drive
smoke away from smoke detectors.
Dead air spaces are often at the top of a peaked roof, or in the
corners between ceilings and walls. Dead air may prevent smoke
from reaching a detector. See Figures 4 and 5 for recommended
mounting locations.
In insect-infested areas. If insects enter a detector's sensing chamber,
they may cause a nuisance alarm. Where bugs are a problem, get
rid of them before putting up a detector.
Near fluorescent lights, electrical "noise" from fluorescent lights may
cause nuisance alarms. Install smoke detectors at least 5 feet (1.5
meters) from such lights.
WARNING:
Never remove batteries to stop a nuisance alarm. Open a window
or fan the air around the detector to get rid of the smoke. The alarm will turn
itself off when the smoke is gone. If nuisance alarms persist, attempt to clean
the detector as described in this User's Manual.
WARNING:
Do not stand close to the detector when the alarm is sounding.
The alarm is loud in order to wake you in an emergency. Too much exposure
to the horn at close range may be harmful to your hearing.
Installing Your Smoke Detectors
Read"Locations to Install Your Smoke Detectors" and "Locations
not to Install Your Smoke Detectors" section in the manual first, and
then decide where to install the detector.
Please follow these steps to install your smoke detector:
1. At the place where you are going to install the detector, draw a
horizontal line six inches long.
2. Remove the mounting bracket from your unit by rotating it
counterclockwise.
3. Place the bracket so that the two longest hole slots are aligned on
the line. In each of keyhole slots, draw a mark to locate a mounting
plug and screw.
4. Remove the bracket.
5. Using a 3/16-inch (5mm) drill bit, drills two holes at the marks and
insert plastic wall plugs. Put the detector away from getting plaster
dust on it when you drill holes for mounting.
6. Using the two screws and plastic wall plugs (all supplied), attach the
bracket to the wall.
7. Line up the slot of the bracket and the detector. Push the clockwise
to fix it into place. Pull outward on the detector to make sure it is
securely attached to the mounting bracket.
