Foghorn 2+0.5 NV-V4


This durable, low maintenance foghorn, is suitable for installation in a Zone 1 hazardous Area. An efficient design using special amplifiers only require 3 stacked emitter to achieve the range of 2 NM.

A 4th ermitter and amplifer set provide the required secondary 0.5 nautical miles fog signal. This horn is completely independently operated and controlled, but integrated into one design.

At the base of the horn the oscillator and termination panel is positioned, to provide an optimal sonorous output.
