Ideal for: offshore platforms & drilling rigs, offshore wind farms, bridge navigation, CALM, SALM & SPM buoys, FPSOs

The LIEX‐710/23 is a compact, lightweight, and reliable sound emitter designed for use in marine applications. Proven in over 40 years of service in the marine environment, the LIEX‐710 horn’s rugged construction and water proof design make it ideal for mounting on offshore oil platforms and drilling rigs, offshore wind farms, calm buoys and floating production systems (FPSOs).

Key Features

Resonates at about 670 Hz

Designed at an optimum frequency to maximize range rating for both U. S. Coast

Guard and IALA criteria

Omnidirectional audio output

Microprocessor‐based control electronics

Remote control terminals for a fog detector, a remote coder or an “at will” switch ‐ a

fog detector is useful on manned platforms where running the foghorn continuously

is a noise irritant; working without human intervention, the foghorn/fog detector

automatically activates the foghorn in low visibility when it is required by regulations

and prevents it from sounding under all other conditions

Power supply includes remote code selector terminals for changing the sounding

rhythm and terminals for synchronizing the horn with other horns or lights

Synchronizing may also be accomplished by a centralized master coder

Terminals are also provided for a 2‐hour temporary silence control ‐ this switch

allows a technician to temporarily disable the foghorn; after the time out period,

foghorn returns to sounding its designated code without the technician having to

remember to manually switch the foghorn back on
