DESCRIPTION
The DF-72/EC is a high quality, photoelectric smoke detector with a
built-in supervised digitally-coded radio transmitter. The DF-72/EC
monitors and then transmits alarms, low battery, and test signals. The
DF-72/EC sounds a local alarm as soon as smoke is detected. Twenty
seconds after the local alarm sounds, the DF-72/EC’s transmitter
will send an alarm signal to the console. The alarm signal will
be repeated every 20 seconds as long as smoke is still present.
Coding switches are not required or used in the DF-72/EC. Each transmitter
is pre-coded at the factory to a unique code. With the DX format, there are
more than one million codes possible.
The smoke detector and transmitter are powered by two 9-volt
batteries. These batteries are supplied with the transmitter and can
power the unit for up to two years. If the battery voltage drops below
a preset level, a low battery report is sent to the receiver every hour.
☞ NOTE: After replacing batteries, press transmitter test button to reset
“low battery circuit”
STEP 1 Remove mounting plate. Remove the unit’s mount-
ing plate by turning the plate counterclockwise.
STEP 2 Identify components. Examine the DF-72/EC to
identify the component locations.
STEP 3 Install batteries. Connect the two 9-volt batteries
and place them into the battery compartments.
STEP 4 Pick smoke detector location. Referring to the
NFPA standard on the back of this sheet, select a good loca-
tion to mount the DF-72/EC. Mounting the DF-72/EC on foil-
backed wallpaper or on a metal single-gang electrical box is
not recommended because the radio range will be reduced.
STEP 5 Install mounting plate. Use the two screws and
anchors provided to attach the mounting plate to the wall or
ceiling. Alternately, the mounting plate can be attached to a
plastic single-gang electrical outlet box. For the best radio
range, observe the “best signal” label on the bottom of the
unit.
STEP 6 Program into receiver. Follow the DF-16/EC
console’s instructions to set it in a program or learn mode.
Press the transmitter test button (not the smoke detector’s test
button) to send a test signal. The transmit LED should light.
Verify that the signal was received and that the transmitter was
properly entered into the console’s memory.
