The feature of the pre-action sprinkler system is that it can take into account both dry and wet sprinkler systems. The system uses the deluge valve to link with the alarm system. The sprinkler is closed and there is no water in the pipeline. Once the alarm is issued, it can be pre-filled with water, changing from a dry to a wet system. This kind of system is more demanding, and the advantage is that there is no water in the pipeline at ordinary times, which can prevent accidental spraying or freezing and cracking, and is especially suitable for places where water is avoided.
