TEST SYSTEM STANDARD FOR ALARM LOCATION
The DXS-72/EC should be installed as follows:
2:1.1.1 Smoke alarms shall be installed outside of each separate
sleeping area in the immediate vicinity of the bedrooms and on each
additional story of the family living unit including basements and
excluding crawl spaces and unfi nished attics. In new construction, a
smoke alarm shall be installed in each sleeping room.
2-1.1.2 For family living units with one or more split levels (i.e.,
adjacent levels with less than one full story separation between
levels), a smoke alarm required by 2-1.1.1 shall suffi ce for an
adjacent lower level, including basements. (Exception: Where there
is an intervening door between one level and the adjacent lower
level, a smoke alarm shall be installed on the lower level.)
✔ Ceiling mounted smoke alarms should be located in the center
of the room or hall, or not less than 4 inches from any wall. When the
alarm is mounted on a wall, the top of the alarm should be 4 to 12
inches from the ceiling.
✔ Do not install smoke alarms where normal ambient
temperatures are above 100°F (37.8°C), or below 40°F (4°C). Also,
do not locate alarm in front of air conditioners, heating registers, or
other locations where normal air circulation will keep smoke from
entering the detector.
A-2.5.2.1
Smoke Detection - Are More Smoke Alarms Desirable?
The required number of smoke alarms might not provide reliable
early warning protection for those areas separated by a door
from the areas protected by the required smoke alarms. For this
reason, it is recommended that the householder consider the use
of additional smoke alarms for those areas for increased protection.
The additional areas include the basement, bedrooms, dining room,
furnace room, utility room and hallways not protected by the required
smoke alarms. The installation of smoke alarms in kitchens, attics
(furnished or unfurnished), or garages is not normally recommended,
as these locations occasionally experience conditions that can result
in improper operation.

IMPORTANT!!!
Linear radio controls provide a reliable communications link and fi ll an important need in
portable wireless signaling. However, there are some limitations which must be observed.The
radios are required to comply with local rules and regulations as radio devices. As such, they
have limited transmitter power and therefore limited range.
A receiver cannot respond to more than one transmitted signal at a time and may be blocked
by radio signals that occur on or near their operating frequencies, regardless of code settings.
Changes or modifi cations to the device may void regulatory compliance.Infrequently used
radio links should be tested regularly to protect against undetected interference or fault. A
general knowledge of radio and its vagaries should be gained prior to acting as a wholesale
distributor or dealer, and these facts should be communicated to the ultimate users.
The purpose of an early warning smoke alarm is to detect
the presence of fi re in its early stages, and sound an
alarm giving the occupants more time to exit the premise
before the smoke reaches a dangerous concentration level.
KNOW FIRE HAZARDS. No detection device can protect life in
all situations. Therefore, safeguards should be taken to avoid such
potentially dangerous situations as: smoking in bed, leaving children
home alone, cleaning with fl ammable liquids such as gasoline.
The best fi re protection is minimizing fi re hazards through proper
storage of materials and general good housekeeping techniques. A
cluttered basement, attic, or other storage area is an open invitation
to fi re.
Careless use of combustible materials and electrical appliances, or
overloading of electrical outlets are other prime causes in starting
fi res.
It is most important that explosive and/or fast burning materials be
eliminated from the home, if at all possible.
Even after proper precautions have been taken, fi res can start. Be
prepared.
FIRE PREVENTION AND ESCAPE
IN CASE OF FIRE. Leave immediately. Don’t stop to pack or
search for valuables. In heavy smoke, hold your breath and stay
low - crawl if necessary. The clearest air is usually at the fl oor.
If you have to go through a closed door, carefully feel the door and
door knob to see if undue heat is present. If they seem relatively
cool, brace your foot against the bottom of the door with your
hip against the door and one hand against the top edge. Open
it slightly. If a rush of hot air is felt, slam the door quickly and
latch it. Unvented fi re tends to build up considerable pressure.
Be sure all the household realizes and understands this danger.
Use your neighbor’s phone or a street fi re alarm box. The job of
extinguishing the fi re should be left to the professionals. Too many
unforeseen things can occur when inexperienced people try to
extinguish a fi re.
BE PREPARED. Perform fi re drills regularly. Use them to
assure recognition of an alarm signal. For your protection,
simulate different circumstances (smoke in hall, in living
room, etc.). Then have everyone react to the situation.
Draw a fl oor plan and show two exits from each room.
Frequently a knotted rope or ladder from a window will
serve this purpose. It is important that children be instructed
carefully, because they tend to hide in times of crisis.
It is imperative that one meeting place outside the home be
established. You should insist that everyone meet there during
an alarm. This will eliminate the tragedy of someone re-
entering the house for a missing member who is actually safe.
If you have children and/or invalids residing in your household, you
can help your fi re department. Most fi re departments have window
decals available for use in children’s or invalid’s bedrooms. Properly
used, these decals will quickly identify sleeping quarters of these
individuals and show the fi re department where to look fi rst for
members of your household.
