Project Description

FW 1

Fog Signal

The FW 1 Fog Signal is a 0.5NM omnidirectional foghorn emitting a 360 degree beam of sound.

Developed specifically for marine applications and ideal for offshore wind farms and oil and gas platforms the fog signal has a corrosion resistant aluminium housing and a custom made driver that is well protected against the salt marine environment.

In addition its compact, lightweight design makes it easy to transport, whilst safety latches enable easy access during configuration and maintenance.

The FW 1 is equipped with one compressor driver and with an integrated power amplifier.

The explosion proof FW 1 Ex version is available for ATEX zones 1 and 2.
