    Advantages

    • decades of experience
    • best material and workmanship - made in Germany
    • with optional microphone attached to foghorn
    • optional body heating for cold areas available on request
    • control and amplifier unit provided with reverse polarity protection of supply voltage
    • low power consumption of 170 W
    • easy installation
      • only 4-core cable required for standard design
      • low weight
    • easy exchange of all parts with onboard tools
    • the whole system runs on 24V DC.

    Sound Characteristics

    • broad frequency spectrum with many higher harmonics
    • signals with strong overtones for best penetration of background noise level
      Even when a background noise covers the actual basic frequency the residual tone forms a base frequency in the human hearing. Two or three harmonics are sufficient for the hearing to perceive the basic frequency.
    • sound frequency of 310 Hz very advantageously ranks in the lower admissible range (250-700 Hz)

    Construction

    • full compliance with the COLREGS 1972
    • type approved by all well known international authorities, certificates by the classification societies on request
    • usage
      • vessels of 20 m but less than 75 m in length
      • land alarm, i.e. bunker stations, oil refineries, airports, powerplants, factories
    • system voltage: 24V DC
    • entirely made of best non-corrosion, seawater resistant materials (no plastic)
