The presence sensor or passive infrared motion detector automatically activates the connected player every time the sensor detects a minimum movement. When the last person leaves the detection area and the set timing period has elapsed, the connected player will end the memorized programming. In the case of a crowded room, where a lot of people enter and leave, the motion sensor will continue to detect movements, it is possible to block the detection of the sensor by activating the appropriate Inibhit input. The sensor allows you to independently set a pause between two motion detections, to easily combine audio messages with advertising panels, totems, and other communication systems, some quick interventions to optimize operation in the presence of many people. The PYR L12 motion sensor is designed to be combined with all InOut players.
