Product details

Since 15 July 1986 every vessel with a length above 12 meters has to be equipped with sound signals, according to SeeStrO 1972, rule 33. The MARCO sound signal corresponds to these regulations. They have a watertight loudspeaker (IP67), an electronic controlling unit, a service unit and optional microphone.

Use the operating panel to start foghorn signals with a standard duration of 5 seconds or an individual tone sequence with an interval of 60 or 90 seconds. With the precedence button (manual sound) a manual tone sequence can be made. Devices with a microphone can be used as an interphone and connecting a sound source (radio device, radio, CD player, etc.), transmits these signals to the speaker. Includes mounting set.

The facility is just too expensive. The control cable does not fit through the cable gland, you have to drill through the bushing first. Everything should suit the price. Schol. SVB: Price is relative - the BSH approval of such devices devours a lot of money.
