Old horn / alarm system

[EvanA]

Doing some wiring on my rig, and came across these switches in every compartment. They appear to be wired back to some sort of transformer tied into power for the horn. Possibly alarm system? Ever seen these before?

welcome aboard.

not sure what you are working on, however that all looks to be added by a prior owner. could have been an alarm system

however the open contact switches would have failed quickly, so it definitely was repurposed from something non-marine
