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.
