DESCRIPTION
ꢀ NOTE: After replacing batteries, press transmitter test button to reset
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.
Installation
Instructions
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.
