Worlds first interactive indoor soccer attraction
Beckhoff PC-based control products, supplied by Hayes Control Systems, are providing automation functions at world's first interactive indoor soccer attraction.
Available in the UK and Ireland exclusively from Hayes Control Systems, the switches use piezo technology.
In combination with Beckhoff's KL6023 Wireless Adapter, they provide an excellent solution for modern buildings that constantly change their interior structure.
The batteryless radio switches can now be installed as part of the complete electrotechnical automation of the building.

"Like so many truly breakthrough solutions, the switches are incredibly simple.
Needing no cables or batteries is the staggering concept," explains Gary Francis of Hayes Control Systems.
"The design and rearrangement of buildings can now be greatly simplified, since the operator control elements are no longer restricted to walls.
With a distance of more than 300m between the wireless adapter and the bus terminals station, the receiver can be placed at any position within a building that is beneficial for radio transmission purposes.
What's more is that the fireload is also greatly reduced, particularly in areas with high occupancy." The wireless adapter, which is in a watertight enclosure, gathers all radio signals and forwards them to the controller.
When the wireless switch is pressed, it tensions a spring that, in turn, causes a tiny hammer to hit the piezo element.
The element produces a voltage, which signals the downstream electronics and brings it to life.
The state of the switches is queried and coded within a single byte, with quality and reliability being ensured by triple transmission.
Once the energy is used up, the electronics goes back to "sleep".
When the switch is released, the process is repeated and the bit indicating the state of the switch is reset to zero, so the control knows the activation duration.
In addition to the simple on/off signals from the switches, both the current room temperature and set temperature from a solar powered thermostat can be transferred via transmitter modules using EnOcean technology, which does not limit the maximum number of transmitters per receiver unit.
The energy consumption for the radio transmission is extremely low.
Power is provided either by integrated solar cells in the thermostat or through the action of throwing the switch in the light switch.
The solar operated system saves energy generated during the day - providing a power reserve.
The temperature sensor reports four times per hour as well as in the event of a change in temperature.
