SENSOR MODULE FOR THE CAPACITIVE PROTECTION OF OBJECTS
The HDF-TOUCH wireless alarm module enables capacitive protection of objects in museums up to the vehicle size. A sensor plate and a reference plate are connected via a plug-in contact. Objects made of metal, e.g. cups, but also automobiles, can be connected directly. There are 64 levels for the adjustment of the sensitivity. Therefore an alarm is triggered before the actual physical contact. A maximum battery life of 12 months is possible, depending on the selected sensitivity and type of object. The operating time of the sensor module can be extended to several years by using external batteries. After that time, the battery must be changed or recharged. The integrated 868 Mhz transmitter module achieves a high range even in solid buildings such as castles and palaces. The Human Detector Flex sensor HDF-TOUCH can be combined with all alarm and voice output devices (such as HDF-BUZZER and HDF-SPEECH) and the alarm monitoring unit HDF-AMD.
