dsound® ALC1 Lighting technology



The first acoustic lighting controller for parking garages,  stairways and hallways.

Many people are familiar with the following problem:

Compliance with statutory minimum lighting for public transport routes and corridors causes high power requirements. Because of that energy costs are one of the biggest cost drivers.
An alternative, temporary control lighting system via motion detector due to their short range is very expensive resepectively complex and is thereby hardly able to generate savings.

With the dsound ® ALC1 there is now the first lighting control, that achieves maximum energy savings and accounts the special needs of parking and garage operators despite the high safety standards.


The advantages are obvious:
  • up to 80% less energy costs
  • range up to 1500 qm (with one sensor!)
  • high security due to individual lighting control
  • simple configuration via remote control

Application areas

Wherever minimum illumination is required by law or allowed, f.ex.
  • in parking garages
  • car parks
  • stairways
  • corridors
