FM-200 fire supression
second 0: the detector reacts to the smoke. the first alarm is raised.
second 15: the main alarm goes off - it's good advice to wear ear protection now
second 30: the valve of the gas bottles are opened (picture) which is really LOUD (even with ear protection)
second 35: a couple of hundred (more like thousands) euros worth of the fire suppression agent have been released. You can't see the hand before your eyes because of the fog
second 40: vision has cleared. the voice sounds slightly deeper
I set fire to the tipps of a whole package of matches. They burn for about 2 seconds getting out immediately once the sulphur (or what ever the chemicals are in the tipp) has burned off. A normal piezo-gas lighter doesn't work at all.
