INSTALLATION 400 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 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 400 Series smoke
alarms.
CAUTION: Turn off electricity to prevent SHOCK and damage to
smoke alarm. Be sure the power line to the 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.
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 elec-
trician.
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.
NOTE: For trouble areas where there can be a large volume of air
blowing out through the electrical junction box. You must first insert
the cardboard shield packaged with your smoke alarm to the
backside of device before securing it to mounting plate.
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. Use UL 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.
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 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 sleeping room, but first read the "Locations to Avoid."
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 7 shows how a
smoke alarm can be exposed to combustion particles in normal
air movement paths, and how to correct this situation.
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. 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 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 at least 5 feet (1.5 meters) away from such
light fixtures.
WARNING: Never disconnect an AC smoke alarm to silence a
nuisance alarm. Open a window or fan the air around the 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
the smoke alarm. 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.
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.
Pg. 4-4
WIRING TWO OR MORE SMOKE ALARMS
Tandem Installation
CAUTION: All smoke alarms in a 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.
