sm electrics’ latest development is a dynamic acoustics controller (DAC) that generates eight individual sounds. The user is able to adjust easily via settings on each device:

  • Starting sound level
  • Ending sound level
  • Sound level’s rising speed

This “soft start” will help raise health and safety levels for personnel working in low noise level environments that do not require ear protection and where standard alarm systems generating maximum sound levels could damage hearing. During “harbor mode” selected light signal devices (LSDs) can drop down operating sound level to a comfortable but safety level, especially used on passenger vessels to avoid unnecessary noise.

A further advantage is that these controllers can be easily integrated in to existing LSDs and will increase reliability.
