Das ZÖLLNER Shipset
ZET-Horn
The ZET-Horn essentially consists of a piston inside a cylinder driven by an AC 3-phase motor and a joining sound horn.These are used on Class I and II ships and are renowned for their clear, far-reaching sound.
Makrofon
The ZÖLLNER MAKROFON is a compressed air powered diaphragm sound transmitter. The signal is triggered by an electromagnet or by manual release. A connection to a power supply is required for electrical operation and heating (230 V AC, 115 V AC or 24 V DC).
Signal automaton
The signal automaton is an electric signal control for fog horns. It is programmed to automatically trigger the manoeuvre and warning signals in accordance with Rule 34 (a, b, d) and Rule 35 (a, b, c, e, g) of COLREG 1972 as well as the SOS distress signal. The 10+ SGA also provides control of the ZBG 110 bell/chime system and the abandon ship alarm.
SRD
The SRD414/4 is an electronic navigation aid for acoustic perception that makes it possible to receive sound signals within a completely enclosed bridge.
Electronic inclinometer
The electronic inclinometer is a heel and pitch measuring system which needs to be fully compliant with IMO recommendations (MSC.363(92)). It is an essential tool for ensuring the safety and stability of the ship.
Bell
According to COLREG 1972 - Regulation 33(a), a vessel of 20 metres or more in length must be equipped with a bell in addition to a horn. We offer various bell systems: electromechanical, electronic and purely mechanical.
Gong
According to the COLREGs 1972 - Rule 33(a), a vessel of 100 metres or more in length must also be equipped with a gong. We offer various gong systems: electromechanical, electronic and purely mechanical.
