There's a big fire in the building and suddenly all the sprinklers turn on -- that's not really how works. Let science extinguish this myth.

Sprinkler system types http://wiginton.net/pdf/Wiginton-Fire-Protection.pdf "Wet - Wet type systems are the most common type of sprinkler system that is installed. A wet pipe system has water in th...
In this video from the FM Global Know More Risk series, learn about the basic differences of the four types of water-based sprinkler systems: wet, dry, deluge and preaction.

This video describes the arrangement, operation and alarm testing of a wet sprinkler system that uses a riser check valve and water flow alarm. This is one of two typical riser configurations for wet systems.
I'm explaining how fire alarm systems work for new technicians or other employees who deal with these systems. This is my 18th video in a string of many Khan Academy-styled lessons. This video introduces how dry sprinkler systems work and how they are monitored by the fire alarm panel.

An alarm valve prevents a reverse flow of water from the installation into the fire-pump room, but in case a fire sprinkler is activated (opened) due to fire, the alarm valve will open and permit water flow into the system. Alarm valve prevents a reverse flow of water or air pressure from the installation into the fire-pump room. In case a fire sprinkler is activated (opened) due to fire, the alarm valve will open and permit water flow into the system and a pressure switch gives a signal to activate the fire-pump. There are different types of alarm valves that need to match the fire sprinkler installation – wet pipe system, dry pipe system. Deluge system etc. Almost all alarm valves are listed by a listing authority like VdS, FM, UL etc.
Explains wet pipe sprinkler systems and its history
Two rooms were identically constructed, except for one was outfitted with a home sprinkler system. This video shows what happens when the two rooms catch on fire. The effectiveness of a home sprinkler system is evident. At the end of the demonstration, one room is completely destroyed, while the other is only wet.
This shows how fire sprinklers work and just how sensitive and fast they operate when heated up. - This head was dropped so it was decided it should not be installed. Thank you Darren for donating this. Cameras: Casio EXF1 Pro (1200 and 600 FPS)
