This animation depicts activation of the BERMAD deluge system preventing fire from spreading to other parts of a building and isolating the nearby flammable material storage from the flames. blog.bermad.com/fire-protecti...
They would need a lot of pressure backing that system, as with that many heads going off, the pressure would drop to almost nothing, that’s why in buildings they have an FDC (fire department connection) that the fire department can connect to to give the sprinkler system a bit of boost for fires that activate many heads, the other type of FDC is a standpipe connection for high rise buildings that the fire department connects to to send water to the upper floors that they can hook up to at the fire
Venkatesan Dhanasekar no. There must be a temperature bulb in each and every sprinkler. Without a bulb, a sprinkler will not be able to activate due to the temperature not being able to be monitored. Also, the smoke alarms might not always go off first, in some cases only one sprinkler in the area of the fire will go off. That will cause the bell to ring and thats how you know to call the fire department.
@@RushGirnty19 This video shows how a deluge system works. In this case, yes all sprinkler heads are open and the pipes only contain air at the atmospheric pressure. When a fire is detected (In this instance by two smoke detectors on two different zones) a deluge valve opens and it allows water to flow to all the sprinkler heads at once.
somehow the video wont play on chrome so I had to open the edge to watch it. its something about chrome's video hardware support needs to be off for some reason..
No because shopping stores don't have deluge systems installed in them. Smoke will only set off the fire alarm, provided there are smoke detectors installed. Regular sprinklers on the other hand need heat to activate and if one head goes off the other ones don't do so by themselves.
The problem with that video is that type of sprinkler system would not see an application in that way. A scenario like that would have a conventional fire suppression system, with automatic sprinklers, that only went off one at a time, most likely. The type of system here is very specialized, and not normally seen outside of the movies. You also have to remember that sprinkler systems are designed for life safety, not property safety. The idea of the system is to keep the fire under control while people inhabiting the building can get out.
