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.
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.

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.
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.

Vancouver Fire Sprinkler System Inspection & Service http://www.bartecfire.com/sprinkler-repair-service/ Sprinklers provide a vital role in protecting a building from fire. When testing a dry sprinkler system, a technician will simulate sprinkler head activation by opening an inspector’s test located at the farthest point of the system. Another technician will observe the activation of the valve in the mechanical room. Once the valve is activated the trip timing and pressures are recorded before the valve is closed and drained. The cover plate can then be removed and the interior of the valve inspected. If the clapper and seat are in good condition and free of debris the valve can be reset and depressurized. The fire alarm panel is checked to confirm alarm and supervisory signals were rec...
