The alarm valve is always on a set condition the system side is full of pressurized water.

One hand the water supplied to system side, on the other hand a small part of water flows to delayer and reach water motor alarm finally to make it alarm. The pressure switch turns pressure signal to electric signal and start fire pump and auxiliary fire-fighting equipments to put out the fire. Water flow inductor will also work and show the position of fire.
The delayer is a cylindrical water storage tank that with inlet and outlet. Because that the pressure of system side will fluctuate that the valve flap will open at a moment but will close right away.
