Step by step RTB has expanded and refined the performance and the spectrum of its products: With the fourth generation of acoustic units we provide communities with a variety of possible solutions. The modular construction makes new combinations possible and allows adjustments to individual situations.
Our single devices have their own electronics and a separate loudspeaker. Both the walk signal and the guide signal are available as single devices.
Our combination devices stand out with a cost saving combination of walk signal and guide signal. In these devices, the values for walk signal and guide signal are freely adjustable as well.
