New gesis® RC Wireless Switching from Wieland

Wieland Electric’s gesis® RC range of radio-controlled switching devices combines gesis® technology with radio technology to provide fast and simple installation with minimal costs and maximum flexibility. Radio technology is ideal for areas within building installations where cables should not or cannot be laid and is ideally suited to operate functions such as lighting and blind control.

These ecologically friendly switches are battery-less, help reduce the amount of cable material used i.e. copper and plastic etc, and lessen the exposure to electro-magnetic fields and emissions. The piezoelectric technology uses the “energy harvesting” principle. The push of a light switch can generate sufficient energy to turn on and off lights up to 30 metres away.

The switches can be freely assigned to the switching outputs and require no special training for the installer or special software. Incorrect control operations are avoided due to the telegram structure and identification mechanisms used. Even if the radio receiver is installed behind metal ceilings, transmission will work without a problem.

The gesis® RC system offers a choice of two way and four way switching modules with the mains supply and outgoing units for the radio devices connected via the popular gesis® connector system. The installation is therefore carried out quickly and error free. In the case of refurbished buildings, the devices can be removed very easily and quickly reinstated.

The system has a range of up to 100m, depending on the layout of the building and the materials used in the fabric of the building. It uses a radio frequency of 868.3MHz with a bandwidth of 280kHz and a sending power of just 10mW for the duration that the switch is pressed with transmission time approx 30 ms for three identical telegrams.

For luminaire connection, only the cable lengths and number of items need to be planned and due to the distributed installation of switchgear, considerable savings can be made on cable, distribution board space and cable trunking. Installers can also save time by having the luminaries already fitted with the corresponding gesis® CON components by the manufacturers which means the simple plug in connection eradicates time consuming wiring errors.

Benefits to the gesis® RC system include no additional materials i.e. back boxes, cables and terminals are required for the switch connections – therefore no additional costs.
