The wireless chime (not within the heat range!) Used as an emergency bell in our professional as sauna. Laying cables would have been unusually complicated. We have tried several wireless solutions. Always the signal was too weak. This Gong we bridge a distance of about 15-20m straight line diagonally through several walls walls and especially by a thick reinforced concrete ceiling. The signal comes to fine. The available signal-tone sequences include signals with good warning function at ordinary volume. Especially promise to come to use batteries everywhere readily available adequate service life and are not Spielkram, as in many other solutions. The function is checked with us every day, and now holds more than 3 months.
