Bell in Romanian Fortress

On my LDS mission in Romania, I visited a little fortress on top of a hill in a small town. In the fortress is this bell which has had several uses.

A few hundred years ago, the bell was rang to warn of attack. During the world wars, it rang for an air raid attack. Now it is used for more general emergencies such as a fire in the town.

When wandering through the fortress, there was a sign next to the bell indicating that it was only to be rung in emergencies, but other than that, there was nothing stopping me from pulling the cord and ringing the bell.

But I think the bell should be rung for other types of attacks and emergencies too. Perhaps it should ring for the economy, or perhaps it should ring to warn of attacks on the traditional family.
