Dry alarm system with dry piped sprinkler system; wetalarm valve is used in wet pipe sprinkler system. The mainfunction of wet and dry alarm valves is to ensure the balance of the air pressure in the automatic fire extinguishing system with the water pressure.

The main function of wet and dry alarm valves is to ensure the balance of the air pressure in the automatic fire extinguishing system with the water pressure. For this, the wet and dry alarm valves comprise a mechanical arrangement with various sub-units which are not uniform. There are valve body, delay cell, water motor alarm gong and pressure switch on the unit.

On the dry pipe sprinkler system, it is possible to see the dry alarm valve mounting scheme. There is a dry alarm valve between the compressed air and the water. These valves, which provide equilibrium and prevent the flow of water, must be installed in the system by specialist engineers. The dry alarm valve, which functions for safety purposes, is one of the units necessary for the safety of the system.

The dry alarm valve is necessary for all fire extinguishing systems based on dry pipe. It is placed in the area where there is no risk of freezing on the system and it is provided to work more efficiently. The water pressure-air pressure balance value can be learned from the installation diagram of the dry alarm valve or directly from the manufacturer. The operating principle of the air supply is to continuously support the dry alarm valve.
