I'm still confused. The long one sound siren is the all clear and the double triple sounding siren is the air raid? I usually only hear the latter.

An oscillating siren is the warning, a steady tone is all-clear.

The long wailing siren is the alert. The double/triple is the "all clear". They used to use these in boot camp for lightning storms...
