Wireless Motion Detector
The wireless motion sensor WNX-40PI-T (passive infrared detector) is operated in combination with a Carephone TA74 or HTS62. This sensor is used to monitor a room and transmit presence information to the Carephone.
The WNX-40PI-T is installed inside the residence in a room that the person requiring assistance has to pass through when they are at home, e.g. in the hallway. The activity monitor in the Carephone can be reset via the daily button or via a wireless motion sensor. In this instance, the WNX-40PI-T serves as an external daily button for the Carephone. The activity monitoring in the Carephone will only be reset if the sensor detects a movement. Unlike triggering via the daily button, the motion sensor doesn’t generate a voice announcement on the Carephone.
Digital quad zone logic
The wireless motion sensor has 78 zones to cover the detection field. More than 4 zones are used to check whether a transmission should be made. This technology improves the accuracy in the detection of people and avoids false detections due to pets.
The sensitivity of the motion sensor is automatically increased at high temperatures, especially in places where the temperature varies between 35 – 37°C, close to that of the human body.
