Is a Cruise Ship s Horn/Whistle system mechanical or electrical or both?

We all know that a Cruise Ship has a horn and sometimes more than one.They are operated using compressed air. But, how does the system to activate the horn work, from the button on the Bridge to the horn/whistle on the funnel or radar mast.

Is it mechanical, (are there moving parts involved), is it electrical (does an electrical signal initiate a set of mechanisms to move)?


Also, is the source of the compressed air from the ship itself, or is it dependent on a secondary source such as (I imagine a very big) air compressor unit?

    who would possibly care?

    but my guess is electrical. a button sends an electrical signal to a solenoid operated valve that turns on the compressed air to the horn.

    but the pushbutton could be pneumatic that turns on pressure that runs in a line to the horn.

    probably varies from ship to ship, depending on builder.
