MOUNTING LOCATION
This smoke alarm can be mounted on a ceiling or wall with
equal efficiency in either location.
Ÿ Ceiling location-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 alarm should be at least 4 inches
from any wall.
Ÿ Wall location-locate the top of the alarm at least 4 inches and
not more than 12 inches from the ceiling. Observe alarm for
proper top/bottom orientation (test knob is near bottom of
unit).

LOCATIONS
Figure 5: RECOMMENDED SMOKE ALARM LOCATION IN
ROOMS WITH SLOPED, GABLED, OR PEAKED CEILINGS.
The placement of the alarm is critical if maximum speed of
fire detection is desired. Thus, a logical location for an alarm is
the center of the ceiling. At this location, the alarm 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, 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 unusu-
ally hot or cold, put the alarm on an inside wall.
Minimum protection requires one alarm as close to the
sleeping area as possible. For better protection, put one alarm
in each room, but first read the "Locations to avoid."
LOCATIONS TO AVOID
Nuisance alarms are caused by placing alarms where they
will not operate properly. To avoid nuisance alarms, do not
place alarms:
Ÿ
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 alarms at least 20 feet (6 meters) away from
kitchens and other areas where combustion particles
are normally present.
Ÿ
In air streams passing by kitchens. Figure 6 shows
how an alarm can be exposed to combustion particles in
normal air movement paths, and how to correct this
situation.
Figure 6
Ÿ
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 alarms at
least 10 feet (3 meters) away from bathrooms.
Ÿ
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 alarm.
Temperature limits for proper operation are 40° to 100°F
(4.4° to 37.8°C).
Ÿ
In very dusty or dirty areas. Dust and dirt can build up
on the alarm's sensing chamber and can make it overly
sensitive, or block openings to the sensing chamber and
keep the alarm from sensing smoke.
Ÿ
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 alarms less effective.
Ÿ
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 an alarm. See Figures 4
and 5 for recommended mounting locations.
Ÿ
In insect-infested areas. If insects enter an alarm's
sensing chamber, they may cause a nuisance alarm. Get
rid of the bugs before installing alarms where bugs
are a problem.
Ÿ
Near fluorescent light fixtures. Electrical "noise" from
nearby fluorescent light fixtures may cause a nuisance
alarm. Install alarms and fluorescent light on separate
electrical circuits.
WARNING: Never remove power from the alarm to silence
the nuisance alarm. Open a window or fan the air around the
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 alarm. The sound produced by the alarm
is loud because it is designed to awaken you in an emer-
gency. Prolonged exposure to the horn at a close distance
may be harmful to your hearing.
INSTALLATION 700 SERIES
In New Construction: DO NOT attach 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 dam-
age to alarm. Be sure the power line to the alarms 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.
