STEP 7 Attach DF-72/EC to mounting plate. Match up
alignment tabs on detector and plate. Turn detector clockwise
until it locks in place.
STEP 8 Test smoke detector. Set the console into a test
mode. Press and hold the smoke detector test button. Con-
tinue to hold the test button for at least 30 seconds after the
noisemaker starts. Verify that the signal was received.
NFPA 74 STANDARD FOR SMOKE DETECTOR LOCATION
The DF-72/EC should be installed in accordance with National Fire Protection Association
(NFPA) Standard 74, which reads as follows:
2-1.1.1Smoke detectors 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*.
The provisions of 2-1.1.1 represent the minimum number of detectors required by this
standard. It is recommended that the householder consider the use of additional smoke or heat
detectors for increased protection for those areas separated by a door from areas protected
by the required smoke detectors under 2-1.1.1 above. The recommended additional areas
are: living room, dining room, bedroom(s), kitchen, attic (fi nished or unfi nished), furnace
room, utility room, basement, integral or attached garage and hallways not covered under 2-
1.1.1 above. However, the use of additional detectors remains the option of the householder.
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 detector required by 2-1.1.1 shall suffi ce
for an adjacent lower level, including basements.

NFPA 74 STANDARD FOR SMOKE DETECTOR LOCATION
Exception: Where there is an intervening door between one level and the adjacent
lower level, a smoke detector 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 (10 cm) from any wall. When the detector is mounted on
a wall, the top of the detector should be 4 to 12 inches (10-30 cm) 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.
FIRE PREVENTION AND ESCAPE
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.
Fires start even with the best of housekeeping and fi re prevention procedures. Fire is an
unexpected event. Early warning detection alerts occupants in time to act.
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.
FIRE PREVENTION AND ESCAPE
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.
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.
FIRE PREVENTION AND ESCAPE
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 reentering 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.

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.
