LOCATIONS TO AVOID
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 6 shows how a
smoke 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 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
the bugs before installing smoke alarms 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.
BATTERY INSTALLATION
1. Remove smoke alarm from mounting plate by rotating counter-
clockwise.
2. Remove AC power connector and unsnap power leads from
top of the old battery. Snap new battery onto snaps and
reinsert battery through hole in back of smoke alarm.
3. Use only Duracell MN 1604 battery with the 7109/7139 Series
smoke alarms.
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. NOTE: 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
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.
WARNING: Smoke 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 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 U.L.
listed Class 1 wire.
NOTE: The wiring to be used shall be in accordance with the
provisions of Article 210 of the National Electrical
Code, ANSI/NFPA 70.
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 smoke
alarm is for tandem connection only. DO NOT USE, AND DO NOT
REMOVE INSULATION CAP UNLESS CONNECTING ANOTHER
SMOKE ALARM.
Figure 8
WIRING TWO OR MORE SMOKE
ALARMS (7109CS/CSX & 7139CS/
CSX only) Tandem Installation
CAUTION: All smoke alarms in tandem installation must be
controlled by the same fuse or circuit breaker. Otherwise tandem
units will not operate. Tandem will operate in the event of AC power
failure if battery is connected to the smoke alarm.
