Theatre Fire?

With heritage listed buildings I would have thought in SA they would have opted for the 'VESDA' [Very Early Smoke Detection Aparatis].

 From memory, when I was acredited in the fire engineering game, I think they are an SA based company. The system was first developed by Telecom for thier remote unmanned exchanges. But for whatever reason they shelved it & it was purchased by a mob in SA, who went on to develop it further & it is now worldwide.

Basicly they are an air asperation system & a very simple unobtrusive system of installed conduit [pipe] work. That constantly samples the air via small holes drilled aqt regular intervalls in the pipe work.

Unlike normal smoke/heat detectors & sprinkler heads, that have to be changed out completrly over a 10 year period, at 10%/year. Besides regular testing only the air sampling chamber needs to be changed out every 5 years, for a factory reworked replacement chamber. A phase VESDA would use occasionaly, was the system could forcast a fire, upto 2 days before it happened. Which they could site cases where this did aqctualy take place. With there latestest Laser series this has been easily proved thru electronic read outs gained from the indivual units. The instalation is suprisingly cheaper than wire to wire method fire systems.

I'm not sure but I think the Old Mill in South Perth, could be heritage listed & they have had a fire sprinkler system installed a while ago in the building. But like almost all things each State differs with localised Acts & rules.

The Phoenix Theatre in Hamilton Hill [WA] is in an unlisted heritage building, while they have a Fire Alarm System they didn't go down the Sprinkler Fire Suppresion route.
