How is the supply valve operated in a dry standpipe system?

In a dry standpipe system, the supply valve is versatile and can be operated in several ways to ensure that emergency personnel can use the system effectively. The valve can be operated manually, allowing firefighters on-site to easily access and control the water supply when needed. Additionally, the option for remote control operation means that the valve can also be activated from a distance, which is useful in situations where immediate access might be dangerous or impractical. Lastly, automatic operation is crucial for scenarios where the system might need to respond quickly without human intervention, such as when connected to fire detection systems. This multi-faceted approach to operating the supply valve adds a layer of flexibility and efficiency, ensuring that the dry standpipe system can provide support in various emergency situations.
