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 pre-
vent 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 unusually 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:
§ 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.
§ 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.
§ 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.
§ 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).
§ 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.
§ 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.
§ 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.
§ 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.
§ Near fluorescent light fixtures. Electrical "noise" from
nearby fluorescent light fixtures may cause a nuisance alarm.
Install alarms and fluorescent lights on separate
electrical circuits.
WARNING: Never remove power from the alarm to silence a
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 emergency.
Prolonged exposure to the horn at a close distance may be
harmful to your hearing.
BATTERY INSTALLATION
1. Remove alarm from mounting plate by turning
counter-clockwise.
2. Remove AC power connector and unsnap power leads from
the top of the old battery. Snap new battery onto snaps and
reinsert battery through hole in the back of the alarm.
WARNING: Units with battery back-up will not provide power or
transmit an alarm to AC only units in the event of
an AC power failure.
All battery back-up units in tandem, with good batteries,
will operate normally during an AC power failure.*
*Strobe will not operate during AC power failure.
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. Use only Duracell MN 1604 battery with
the 7109/7139 Series smoke alarms.
CAUTION: Turn off electricity to prevent SHOCK and damage
to alarm. Be sure the power line to the 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.
WARNING: Alarm installation must conform to the electrical
codes in your area and to Article 760 of the U.S. National
Electrical Code. 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 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 alarm, to the back side of the
mounting bracket before it's secured to the junction box.
WIRING ONE ALARM
(7109CS/CSX & 7139CS/CSX only)
1. Run a minimum of 16 gauge, 2-conductor cable, plus
ground (3 wires) to the alarm junction box from a power
supply. Smoke alarms should be run on their own
dedicated circuit. Use U.L. listed Class 1 wire.
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 7.
NOTE/RED-YELLOW WIRE: The red-yellow wire from the
alarm is for tandem connection only. DO NOT USE, AND DO
NOT REMOVE INSULATION CAP UNLESS CONNECTING
ANOTHER ALARM.
