Sound signal reception system for ships
VSS Zenitel Norway AS

The VINGTOR Sound Signal Reception System (VSS) is an acoustical electronic navigational aid that enables the officer on watch at a “Closed bridge” according to SOLAS, to hear environmental sound signals from other ships or foghorns that are audible outside the ship when standing inside a totally enclosed bridge space.

The system is monitoring, according to requirements, frequencies between 70 and 820 Hz. Four VSS-222 weatherproof microphones are mounted outside the wheelhouse and connected to the VSS-111 audio amplifier and loudspeaker within the bridge.

Detects direction

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 on the direction of the received sound signal.
