PRODUCT DESCRIPTION
The DXT-72 is a photoelectric smoke alarm with a built-in
transmitter designed for use with Linear’s DX Format receivers.
When smoke is detected, the alarm sounds a loud local
alarm. Twenty seconds after the local alarm sounds, the built-
in transmitter sends a digitally coded wireless signal to its
companion receiver. The wireless signal will be repeated every
20 seconds as long as smoke is still present.
The digital DX code format features over a million possible
codes. The DX transmitters are precoded at the factory to unique
codes, so no fi eld coding is required. The DXT-72 can send three
different codes: alarm, test and low battery.
For versatility,
any transmitter can be programmed into any
receiver channel.
Receivers must be programmed to the
transmitter’s code before system testing and operation. Refer to
the receiver’s instructions for details on programming.
The unit is powered by two 9-volt alkaline or lithium 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 the alarm will sound low battery beeps and a
low battery signal will be sent to the receiver every hour (some
receivers can report low battery, others cannot).
☞
NOTE: After replacing batteries, press transmitter test
button to reset “low battery circuit”.
