 To control the pedestrian access can be a more complicated task than could be usually thought. The solution that we propose can help you in this task: ParkNet/XM is a proximity module that allows to control the pedestrian access trough a contactless card or a key tag. It’s very sophisticated, but at the same time it is easy to use and install, compact, flexible and cheap. It can be used to open or close doors, gates or other accesses only by bringing the card near the antenna, from whose power depends the action range of the system. ParkNet/XM requires a low voltage power supply, while the cards work without batteries.
 The system is mechanically installed in the 511 module of the Siedle Vario system that has small size: 93X93X54 mm.
The modern and beautiful aspect surely helps the installation in every area; it is quite difficult to find an access control with an attractive design like ParkNet/XM.
 The built-in module can be directly inserted in a wall mount embedded pabel, with other components as intercoms or switches, or as the only one; alternatively it can be installed in an apposite column, in this case with other functions or alone too.
 To control the accesses the system compares the world unique 9 digit number of every card with a list of ID number into the internal memory of the ParkNet/XM in the independently function mode, or it sends the identification request to the ParkNet system in the online mode.
The cards and the key tags are automatic identification device, based on proximity techniques using radio-frequency transmissions. When they receive a transmission request through a radio wave sent by the ParkNet/XM module, the cards identify themselves transmitting their ID number.
