The ZÖLLNER ZET horn was the first piston-driven ship's horn on the market, powered by a 3-phase motor. Power from the motor is transmitted to the piston via gears, crankshaft, and connecting rod. This piston oscillates at a specific frequency, which, through the resonance of the horn and the moving
