Some are atom bomb shelters.

Some are in the open, possibly a car park - away from the building where the alarm has been activated - usually a fire alarm.

Some 'multi purpose' assembly points would also be used for bomb threats.
For bomb threats the location should not be known nor regular as the bomb could be placed within the assembly point to cause maximum devastation.
This kind should not be mapped.
