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.
