When to use the Alarm function?

[Egobyte83]

When should you use the alarm function? The description says that it is a mechanic to make settlers take cover during hostile raids, but I feel like it is something that should help during things like fallout situations and somesuch as well. Logically, people taking shelter would benefit from the alarm function during catastrophes, since they would be forced into cover... but I can't help but feel that everything tanks while it is in place, and not just happiness, but production too. Nothing gets built, and sick people can't get to medical facilities, etc. And that is only if it was designed to have a use during disasters, which it quite possibly doesn't. But at the same time, having people just walk around in the open during a fallout event seems very... weird.

This function is confusing to me.

When I first started playing I had the same question, I tried to make as many medical tents as I can and staff them before hand when I get that weather warning as soon as I can by removing them from their main jobs, but this is barely practical on small colony, on a large one forget about it. Now I more favour a mass death as long as I have a few surviver outposts on the world map to restock the population.
