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 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 room, but first read the "Locations to Avoid."
LOCATIONS TO AVOID
WARNING!
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 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.
In damp or very humid areas
, or next to bathrooms with showers.
The moisture in humid air can enter 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 bugs
before installing devices where bugs are a problem.
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 380LSb Series
smoke alarms.
Notice: Visual signal will not operate during AC power failure.
Figure 5: RECOMMENDED SMOKE ALARM MOUNTING
LOCATIONS.
Figure 5
MOUNTING LOCATION
Wall location-locate the top of the smoke alarm at least 4 inches
and not more than 12 inches from the ceiling and must be within
16 feet of pillow. Observe smoke alarm for proper top/bottom
orientation (test knob is near bottom of unit).
Smoke alarm with visual signal is to be mounted per NFPA 72
Annex A. 11.8.3. Ceiling location - smoke 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 unit should be at least 4
inches from any wall and must be within 16 feet of pillow. Wall
location-locate the top of the smoke alarm at least 4 inches and
not more than 12 inches from the ceiling and must be within 16
feet of pillow. Observe smoke alarm for proper top/bottom
orientation (test knob is near bottom of unit).
380LSb MOUNTING: PLATE & SMOKE ALARM
The 380LSb is supplied with a 9 foot line cord for
installation to a normal outlet box. For this type of installation:
1. Care should be taken to lace cord through slots in base as shown
in Figure 7 to insure cord does not interfere with engagement of
the mounting bracket.
2. Determine proper location for smoke alarm above a receptacle
that is
NOT CONTROLLED BY AN "ON-OFF" SWITCH.
3. If screw anchors are used, drill two 3/16" holes, insert the screw
anchors, and mount the plate to wall using screws.
4. Mount the smoke alarm to the bracket as illustrated in Figure 8.
5. Use the enclosed cord retainer clamp as illustrated in Figure 7
to insure the unit is not accidentally disconnected.
Warning! This unit must be installed within 16 feet of the pillow
with an unobstructive view of occupant.
