PUBLIC ADDRESS FOR TUNNELS – SAFETY FOR TUNNEL
Voice alarm systems utilised in tunnels need to provide a function to set up delays in sending acoustic signals. MULTIVES offers in-built functionality to define such delays thus eliminating a need for 3rd party products to synchronise acoustic waves emitted through loudspeakers.
MULTIVES offers dedicated directional high-power speakers ensuring superb quality of emitted acoustic pressure. Those speakers can be installed in the tunnel at regular intervals to ensure precise sound propagation, required noise levels, broader bandwidth and reduction of bounce. Their design and characteristics guarantee the highest level of sound clarity.
Each fireman microphone contains in-built communication card enabling fibre-optic connectivity therefore eliminating the need for additional convertors or transporting microphones across significant distances in the tunnels.
