PRODUCT DESCRIPTION
The DXS-72/EC is a photoelectric smoke alarm with a built-in
transmitter designed for use with Linear’s DXS and 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 DXS code format features over a million possible codes.
The DXS transmitters are precoded at the factory to unique codes,
so no fi eld coding is required. The DXS-72/EC can send three
different codes: alarm, test and low battery status.
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. Every hour, the DXS-72/EC will send a status
transmission to the receiver. The hourly signal updates the receiver
to the transmitter’s condition. By monitoring status transmissions, the
receiver can determine if a transmitter has a low battery or has been
removed from the system. 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 with status reports (some receivers can
report low battery status, others cannot).
☞ NOTE: After replacing batteries, press transmitter test button
to reset “low battery circuit”.
