How the fire sprinklers get activated automatically ?

1 Answer

Answer :

The simple answer is probably not, but it is possible. Wet fire sprinkler systems are designed to operate in conjunction with fire alarm systems, but do not depend on them to discharge water. Pulling a fire alarm station activates an alarm, it does not activate most sprinkler systems. Most building sprinkler systems are “wet” systems. The hidden plumbing is full of water waiting to be released through the sprinkler heads. The sprinkler heads are designed to serve as “valves” that prevent the flow of water until there is enough heat present to either melt the fusible link or burst a temperature sensitive glass bulb. In either case, water begins to flow only through that particular head. TV and movies frequently show all the heads discharging water- and though there are systems designed to operate that way, they are used in very specific applications. Most sprinkler systems are designed so that only the heads in the fire area discharge water. Typically, the pull station activates the fire alarm (sounds, strobe lights and alerts the fire department) and the sprinkler activates when there is enough heat to open it.
