The DXT-54 is a battery powered passive infrared motion detec tor with

PRODUCT DESCRIPTION

a built-in transmitter designed for use with Linear’s DX Format
receivers. This transmitter can be used in a variety of motion detection
applications. When the passive infrared sensor detects motion in its
field of view, the transmitter sends a digitally coded wireless signal to
its companion receiver.

The digital DX code format features over a million possible codes. The
DX transmitters are precoded at the factory to unique c odes, so no field
coding is required. The DXT-54 can send two different codes: alarm
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.

In a typical installation, the motion detector is mounted indoors in a
corner or on a wall between six and eight feet high. The sensor will
monitor the infrared level in its detection pattern. If the level increases
or decreases rapidly (as when a person or animal moves through the
area) the transmitter triggers, sending an alarm signal to the receiver.

The unit is powered from a 9-Volt alkaline battery with an expected
battery life of up to three years depending on the area’s traffic. When
the battery gets low, the test indicator will flash during motion and any
alarm transmission will also send a low battery signal to the receiver
(some receivers can report low battery, others cannot).

To conserve battery life, the detector will trigger the transmitter
only once every four minutes. When testing, remain out of the
detection area for at least five minutes before walking in front of the
unit to cause an alarm transmission.

For setup and testing, pressing the detector’s test button places the
unit in walk test mode for four minutes. The installer can walk in front
of the unit while viewing the test indicator behind the detector’s lens to
determine the detection area. In walk test, an alarm signal is sent each
time the walk test indicator lights.

Linear radio controls provide a reliable communications link and fill an important need in portable wireless
signalling. However, there are some limi tations which must be observed.

For U.S. installations only: The radi os are required to comply with FCC Rules and Regulations as

Part 15 devices. As such, they hav e limited transmitter power and therefore limited range.

A receiver cannot respond to more than one transmitt ed signal at a time and may be blocked by

radio signals that occur on or near their operating fr equencies, regardless of code settings.

Changes or modifications to the device may void FCC compliance.

Infrequently used radio links should be t ested regularly to protect against undetected interference

or fault.

A general knowledge of radio and its vagaries shoul d be gained prior to acting as a wholesale

distributor or dealer, and these facts s hould be communicated to the ultimate users.
