Marco EW2 electronic horn with fog signal is a complete 12 V marine sound signal system for pleasure and commercial vessels between 12 and 20 meters. The system functions as a standard horn and features an automatic fog signal function. It delivers a sound level of over 120 dB at a distance of 1 meter and operates at a frequency of 690 Hz.
The system consists of a horn/speaker unit, a built-in membrane control panel, an electronic control unit, and a mounting kit. The horn is connected to the control unit with two wires, providing a simple electrical installation. The control panel uses an RJ45 connection and features IP67 protection; the IP rating applies to the control panel and not the entire horn system.
