The luxurious wireless gong has an extreme coverage range and fulfils the highest functionality demands. It functions as a bell or signal system. Individual designs are taken care of by the 12 interchangeable motif cards (included in delivery). Several Mistral 600 sets can be combined. A different ringtone has to be set for each transmitter. A flash signal can be adjusted on this device and is therefore suitable for the hearing impaired also. Several sets can be used as distance multiplicators, on demand. The transmitter can also be wired with an already existing bell system.
