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
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.
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 ANSI/UL 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, 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.
NOTICE: 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 ANSI/UL listed Class 1 wire.
NOTICE: THE WIRING TO BE USED SHALL BE IN ACCORDANCE WITH THE
PROVISIONS OF ARTICLE 300.3(B) OF THE NATIONAL ELECTRICAL CODE,
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.
NOTICE: 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.
