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, 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, 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
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 units 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 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.
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 units 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 disconnect an AC smoke alarm to silence the 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 700 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 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.
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.
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
PACKAGED WITH YOUR SMOKE ALARM, TO THE BACK SIDE OF THE
MOUNTING BRACKET BEFORE IT IS SECURED TO THE JUNCTION BOX.
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 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.
