Approved EW3-MS Electronic Horn With Amplifier, Fog Signal & Siren - 20-75m

The EW3-MS by Marco is an approved electronic whistle complete with loudspeaker, built-in membrane control panel and electronic controller. The horn also includes a microphone and has an extra fog horn/siren preset when compared to the EW3-M model.  The EW3-MS features a new ultrasonic heating system for improved acoustic membrane performance.

The system has a number of built-in functions:

• Manual tone - this can be installed across contacts marked 1 and 2 in order to ensure that it always has priority over any other function being used.
• Multiple fog horn signals - This signal can be repeated at 60 or 90 second intervals.  The default signal is a tone with a 5 second duration.  It is possible to preset two different fog horn signals (connection terminals 1 and 3 or connection terminals 1 and 4).
• Customised tone - The default fog horn 5 second signal can be substituted by a customised tone setting.
• Amplifier with auxilary input for connection of other devices.

This electronic horn meets COLREG 1972 IMO class III international regulations with RINA, LLOYD'S REGISTER MCA, BUREAU VERITAS, NMMA and BSH homologations.

Includes mounting kit and control panel.
