High pressure fogging systems

[jean2]

We've had a local DJ that has a permanent setup at a club called in after
his fog machine decided it was going to start on it's own and filled the
whole club with fog... emptied the juice completely....
There are two types of smoke detectors one is the type required in
residential buildings which is much more sensitive to just about anything
including steam from a shower then there are the commercial building ones
which must have huge amounts of smoke, steam etc in order to set off... Most
hotels use a hybrid type that cigarette smoke or steam from the shower won't
set off...
