Direct Low Pressure System is a kind of fire suppression system that is designed for protecting facilities, buildings, and many other structures from fire. The LPCB is a UK-based certification body that offers independent 3rd party approval of fire and security services and products. It is a water-based system that uses a network of pipes, valves, and nozzles for distributing water throughout the protected zone in the case of a fire. Direct Low Pressure System is designed to operate at low pressure, normally between 1 and 4 bar, which decreases the chance of damage to the contents and structure.
