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 and PERS consoles. In PERS installations, the DXS-54 functions to reset the PERS activity timer. When the passive infrared sensor detects motion in its field of view, the transmitter sends a digitally coded wireless signal to the PERS console.
The digital DXS code format features over a million possible codes. The DXS transmitters are pre-coded at the factory to unique codes, so no field coding is required. The DXS-54 can send three different signals: activity timer reset, low battery, and status.
In a PERS 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 moves through the area) the transmitter triggers, resetting the activity timer and preventing an inactivity alarm.
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 PERS console when the detector senses motion.
Approximately every hour, the DXS-54 will send a status transmission to the PERS console. The hourly signal updates the PERS console to the transmitter s condition. By monitoring status transmissions, the PERS console can determine if a transmitter has a low battery or has been removed from the system.
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 activity timer reset 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 activity timer reset transmission.
