Frequently, one or more pressure gauges are provided for monitoring the pressure in the fluid inlet chamber and / or in the fluid outlet chamber. If the fire extinguishing system valve is not shut off on the inlet or outlet, these pressure gauges then indicate on the inlet side the supply pressure of the extinguishing agent, and on the outlet side the pressure in the downstream network of the fire extinguishing system.
