AWD 2000 - acoustically warning devices - audible safeguarding
For alerting of approaching trains to traffic participants at level crossings there will be used according to validity regulation acoustically warning devices as well. For that there was developed the electronically level crossing acoustic AWD 2000. The acoustic is able to distribute different sound and clock frequency.
Clear audibility of the acoustics under all conditions including loud surrounding noises is important. However, the sound level should not have a disturbing effect on the area around the level crossing (e.g. on residents at night). In order to fulfil this task, the acoustic transducers, designed as loud speakers, can be used to establish the surrounding noise level at the level crossing (optional mode). The measurement data averaged over a fixed period of time serves as the reference value for volume adjustment for the next activation. A automatically day and night regulation is possible as well.
Acoustic is maintenance free.
