Product description

The ZÖLLNER ZETFON 50/650 – Electronic Shiphorn is type approved for marine use (ship classification IV) and produces a powerful horn (Tweeter) for vessels up to 20 meters in length. The ZETFON 50/650 is a robust electrically operated whistle which is equally suitable for all types of inland and maritime navigation.

The ZETFON 50/650 consists of the following components:

ship horn unit (ZETFON 70s)
control unit (ZETFON ZP-7)
built in key (ZETFON 4676)

Advantages

decades of experience
best material and workmanship - made in Germany
control and amplifier unit provided with reverse polarity protection of supply voltage
low power consumption of 50 W
easy installation
the whole system runs on 12 VDC or 24 VDC

Sound Characteristics

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 660 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 less than 20 m in length
- land alarm, i.e. bunker stations, oil refineries, airports, powerplants, factories
system voltage: 12 VDC or 24 VDC
entirely made of best non-corrosion, seawater resistant materials (no plastic)
