Fire sprinklers would never go off in such an instance. As a former firefighter I can attest to this. Out always annoys me when a movie shows someone setting off sprinklers in a movie, either via computer hacking, or setting off one sprinkler head and making them all go off. There are two types of sprinkler heads, frangible bulbs and fuseable links, both operate on the same basic principle, main difference being the material used, glass or metal. The water lines are pressurized, usually with air, specially in cold climates. This pressure is equalized to keep the water valve closed. The sprinkler heads are designed to break (frangible bulb) or melt (fuseable link) at a specific temp., this opens the line at that head, dropping the pressur in the line, opening up the water valve, letting out the water ONLY at the sprinkler head/heads that were subject to enough heat to pop their plugs (fyi most buildings use frangible bulb style now, more dependable....look at a fire sprinkler next time you notice over, you will see what looks like a little red Christmas light at its center, that is the frangible bulb)..........rant over![]()
Rant, what rant, Marine? That was educational!
That's the type of information, precise and totally descriptive
of how things work that I want to read on this forum.
More power to you. I salute you!
(don't mind me if I don't stand at attention for that. I'm vaping.
..Oh shoot. Almost poked out my eye with my stick... saluting...)
