2.1 Safety through innovative technology
More and more systems and devices are using radio frequencies for wireless communication. In addition, many old and new electrically operated installations generate interfering frequencies – often of high intensity. To allow you to transmit the correct information in spite of this multitude of signals, the Moeller RF system works on a frequency of 868.3 MHz, in the so-called ISM band (industrial, scientific, and medical band), which is specifically regulated and reserved for this purpose.
Moeller uses specially developed and coded radio protocols to ensure that the information transmitted is correctly understood by the receiver. To boost transmission reliability, Moeller relies on a bidirectional system (transmitter waits for confirmation from receiver).
For important technical details, see Section 4 What you need to know about radio waves.
Reliability is also a question of service life. On the one hand, modern, robust electronic components guarantee a long service life for the system. On the other, they are extremely versatile in their range of use. Their design also matches that of the conventional Moeller switch range. Whether you are setting up a new system or retrofitting an existing one, the Moeller wireless system is a sound investment.
2.2 Safety for the user
Fears with regard to radiation are unfounded.
Development and product testing are carried out in accordance with the relevant European standards and EMC guidelines to ensure the Moeller Building Automation 7 highest possible freedom from interference between existing devices and systems.
The transmitter power of the radio components is approx. 1 mW and thus roughly one 200th of the maximum output of a mobile telephone – and that only for the extremely brief duration of a transmission.
Independent institutes have examined the emission of radiocontrolled switches with regard to emissions in domestic and office environments. They concluded that the overall impact (total induction density) of radio-controlled switches was only 1/100th that of conventional switches - and less than 1/1000th that of mobile telephone equipment.
No cases of interference with medical equipment such as pacemakers or hearing aids have been reported.
2.3 Safety through standardisation
All equipment conforms to the Low Voltage, EMC Guidelines and meets the requirements of the R&TTE - Guidelines 1999/5/EC.
Circuits must be protected with automatic cutouts of max. 16A, characteristic B or C.
