The Model DXT-54 Passive Infrared Motion Detector Transmitter is a battery
powered passive infrared motion detector with 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 codes, so no field coding is required. The DXT-54 can send two
different signals: alarm and low battery.
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. The
battery's life can be up to three years depending on the area's traffic. When
the battery gets low, the test indicator will flash and a low battery signal
will be sent to the receiver when the detector senses motion.
To
conserve battery life, during normal operation, the detector can trigger the
transmitter a maximum of once every four minutes.
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
red test indicator through the detector's lens to determine the detection area.
In walk test, an alarm signal is sent each time the walk test indicator lights.
During normal operation, the detector requires a pulse count of three events in
eight seconds before sending an alarm transmission.
