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 an 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
device 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 smoke
alarm from sensing smoke.
Near fresh air inlets, returns or excessively drafty areas. Air
conditioners, heaters, fans, 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 smoke
alarm to remove the smoke. The alarm will automatically turn off
when the smoke in the air is completely gone. Do not stand close to
the smoke alarm. The sound produced by the smoke alarm 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 GN-200 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.
CAUTION: Turn off electricity to prevent SHOCK and damage to
smoke alarm. Be sure the power line to the smoke alarm 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: The wiring to be used shall be in accordance with the
provisions of Article 210 of the National Electrical Code, ANSI/
NFPA 70. 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.
WIRING ONE SMOKE ALARM
1. Run a minimum of 16 gauge, 2-conductor cable, plus ground (3
wires) to the smoke alarm 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.
Figure 8
NOTE/YELLOW-RED WIRE: The yellow-red wire from the smoke
alarm is for tandem connection only. DO NOT USE, AND DO NOT
REMOVE INSULATION CAP UNLESS CONNECTING ANOTHER
SMOKE ALARM.
