Sound Reception System type Vingtor VSS 111
Enables the navigator on an One Man Operated Bridge to listen to environmental sound signals from other ships and fog horns when standing inside the enclosed bridge space.
The VSS system is an acoustical electronic navigational aid that enable the officer on watch at an «one man operated bridge» to hear environmental sound signals from other ships or fog horns that are audible outside the ship when standing inside a totally enclosed bridge space, in order to perform the look-out function as required in the International Regulations for Prevent Collisions at Sea, 1972.
The system is monitoring, according to requirements, frequencies between 70 and 700 Hz.
Four (4) VSS-222 weatherproof microphones are mounted outside the wheelhouse and connected to the VSS-111 audio amplifier and loudspeaker within the bridge.
By use of four microphones the VSS system will detect the direction of the incoming signal and activate the corresponding LEDs at the VSS-111 front panel
The four microphones operate in pair depending of the direction of the received sound signal.
The microphone first detecting the sound will be registrated and it will lock against influence from the other microphone. This will repeat each time a signal is strong enough to trig the detector.
The «bridgewing» pair of microphone will indicate if the sound is coming from the Sb or Ps direction, while the other pair tell if the sound signal is coming from «Fore» or «Aft».
The combination of above will indicate the actual sector
