The Model DXS-54 Supervised Passive Infrared Motion Detector Transmitter is a battery powered passive infrared motion detector with a built-in transmitter designed for use with Linear’s DXS and 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 DXS code format features over a million possible codes. The DXS transmitters are precoded at the factory to unique codes, so no field coding is required. The DXS-54 can send three different signals: alarm, low battery and status.
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.
Approximately every hour, the DXS-54 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. DXS format receivers can monitor status signals, DX format receivers cannot.
