smoke alarm for proper top/bottom orientation (test knob is near
bottom of unit).
Smoke alarm with visual signal is to be mounted per NFPA 72 Annex
A. 29.8.3. Ceiling location - smoke alarm should be mounted as close
as possible to the center of a hallway or room. If this is not possible,
the edge of the unit must be within 16 feet of pillow. Wall location-
locate the top of the smoke alarm not more than 12 inches from the
ceiling and must be within 16 feet of pillow. Observe smoke alarm
for proper top/bottom orientation (test knob is near bottom of unit).

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 PUT 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, put smoke alarms in such units
only on inside walls, not more than 12 inches (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, put the
smoke alarm on an inside wall.
Minimum protection requires one smoke alarm as close to the
sleeping area as possible. For better protection, put one smoke alarm
in each room, but first read the "Locations to Avoid."
LOCATIONS TO AVOID
WARNING! This smoke alarm must be installed within 16 feet of
the pillow. Any location outside of 16 feet will cause this alarm to be
less effective and not meet code requirements.
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 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 device. 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 or 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.
In insect-infested areas. If insects enter a smoke alarm's sensing
chamber, they may cause a nuisance alarm. Get rid of bugs before
installing devices 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 remove power from smoke alarm to silence a
nuisance alarm. Open a window or fan air around device 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 device.
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.
WIRING/GENERAL (7109CS/CSX & 7139CS/CSX ONLY)
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. NOTICE: Use only Duracell MN 1604 battery with the 7109/7139
Series smoke alarms. Available at many retail stores.
CAUTION: Turn off electricity to prevent SHOCK and damage to
smoke alarm. Be sure the power line to device 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 or on separate circuits.
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
(7109CS/CSX & 7139CS/CSX ONLY)
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 attach
an adhesive backed foam gasket, which has been packed with your
smoke alarm, to the back side of the mounting bracket before it's
secured to the junction box.
WIRING ONE SMOKE ALARM
(7109CS/CSX & 7139CS/CSX ONLY)
1. Run a minimum of 16 gauge, 2-conductor cable, plus ground (3
wires) to the device junction box from a power supply. Smoke alarms
should be run on their own dedicated circuit. Use UL 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.
