Figure 6: RECOMMENDED SMOKE ALARM LOCATION IN
ROOMS WITH SLOPED, GABLED, OR PEAKED CEILINGS.
The placement of the smoke alarm is critical if maximum speed
of fire detection is desired. Thus, a logical location for a smoke
alarm is the center of the ceiling. At this location, the device is
closest to all areas of the room.
WHERE SMOKE ALARMS SHOULD BE
INSTALLED IN MOBILE HOMES
In mobile homes built after about 1978 that were designed and
insulated to be energy-efficient, smoke alarms should be installed as
described in the section above.
In older mobile homes that have little or no insulation compared
to today's standards, uninsulated metal outside walls and roofs can
transfer heat and cold from outdoors, making the air right next to
them hotter or colder than the rest of the inside air. These layers of
hotter or colder air can prevent smoke from reaching a smoke alarm.
Therefore, install smoke alarms in such units only on inside walls,
between 4 and 12 inches (10 and 30 cm) from the ceiling. If you are
not sure about the insulation level in your mobile home, or if you
notice that the walls or ceiling are unusually hot or cold, install the
smoke alarm on an inside wall.
Minimum protection requires one smoke alarm as close to the
sleeping area as possible. For better protection, install one smoke
alarm in each room, but first read the "Locations to Avoid."
LOCATIONS TO AVOID
Nuisance alarms are caused by placing smoke alarms where
they will not operate properly. To avoid nuisance alarms, do not
place smoke alarms:
In or near areas where combustion particles are normally
present such as kitchens; in garages where there are particles of
combustion in vehicle exhausts; near furnaces, hot water heaters,
or gas space heaters. Install smoke alarms at least 20 feet (6
meters) away from kitchens and other areas where combustion
particles are normally present.
In air streams passing by kitchens. Figure 7 shows how a
smoke alarm can be exposed to combustion particles in normal air
movement paths, and how to correct this situation.
Figure 7
In damp or very humid areas, or next to bathrooms with
showers. The moisture in humid air can enter the sensing chamber
as water vapor, then cool and condense into droplets that cause a
nuisance alarm. Install smoke alarms at least 10 feet (3 meters)
away from bathrooms.
In very cold or very hot environments, or in unheated
buildings or outdoor rooms, where the temperature can go below
or above the operating range of the smoke alarm. Temperature
limits for proper operation are 40° to 100°F (4.4° to 37.8°C).
In very dusty or dirty areas. Dust and dirt can build up on the
smoke alarm's sensing chamber and can make it overly sensitive, or
block openings to the sensing chamber and keep the device from
sensing smoke.
Near fresh air inlets, returns or excessively drafty areas. Air
conditioners, heaters, fans, and fresh air intakes and returns can
drive smoke away from smoke alarms, making the devices less
effective.
In dead air spaces at the top of a peaked roof or in the
corners between ceilings and walls. Dead air may prevent smoke
from reaching a smoke alarm. See Figures 5 and 6 for
recommended mounting locations.
In insect-infested areas. If insects enter a smoke alarm's
sensing chamber, they may cause a nuisance alarm. Get rid of the
bugs before installing smoke alarms where bugs are a problem.
Near fluorescent light fixtures. Electrical "noise" from nearby
fluorescent light fixtures may cause a nuisance alarm. Install
smoke alarms and fluorescent lights on separate electrical
circuits.
WARNING! Never disconnect an AC smoke alarm to silence a
nuisance alarm. Open a window or fan the air around the unit to
remove the smoke. The smoke alarm will automatically turn off
when the smoke in the air is completely gone. Do not stand close to
the unit. The sound produced by the device is loud because it is
designed to awaken you in an emergency. Prolonged exposure to
the horn at a close distance may be harmful to your hearing.
INSTALLATION 9000 SERIES
CAUTION: New Construction: DO NOT attach smoke alarm head
until AFTER sanding, painting, and other dust creating situations are
finished and cleaned up.
WIRING/GENERAL
1. Use U.L. Listed cable with Class 1 insulation.
2. Observe local code requirements. Use box connector to anchor
cable to outlet box.
3. Metal outlet boxes must be grounded to earth ground.
4. Use only Duracell MN 1604 battery with the 9000 Series smoke
alarms.
CAUTION: Turn off electricity to prevent SHOCK and damage to
smoke alarm. Be sure the power line to the unit is not controlled by
any on/off switch, or other type of switch, other than a fuse or circuit
breaker.
IMPORTANT: Insure that all fluorescent lighting fixtures are properly
grounded.
NOTICE: Smoke alarm installation must conform to the electrical
codes in your area and to Article 760 of the U.S. National Electrical
Code. Wire installation should be performed only by a licensed
electrician.
MOUNTING OUTLET BOX
Use a 2" x 3" switch box or a 4" square or octagon junction box.
Mount a box for each smoke alarm. If wall mounting is desired, be
sure the box screws are oriented to upper right and lower left
corners. Be sure to use supplied Mounting Plate.
NOTE: For trouble areas where there can be a large volume of air
blowing out through the electrical junction box. You must first insert
the cardboard shield packaged with your smoke alarm to the
backside of device before securing it to the mounting plate.
WIRING ONE SMOKE ALARM
1. Run a minimum of 16 gauge, 2-conductor cable, plus ground
(3 wires) to the junction box from a power supply. Smoke
alarms shall be connected to their own dedicated circuit. Use
U.L. Listed Class 1 wire.
NOTE: The wiring to be used shall be in accordance with the
provisions of Article 300.3(b) of the National Electrical Code,
ANSI/NFPA 70, as well as Article 210.
2. Make wire connections to the supplied plug-in connector as
follows: black to black, white to white, and connect the ground
wire to the metal outlet box.
NOTE/RED-YELLOW WIRE: The red-yellow wire from the smoke
alarm is for tandem connection only. DO NOT USE, AND DO NOT
REMOVE INSULATION CAP UNLESS CONNECTING ANOTHER
SMOKE ALARM.
