Fire Sprinkler Zone Control Valve Layout With Flow Switch Detail

This fire sprinkler zone control valve layout drawing illustrates the detailed arrangement of fire protection piping components used in sprinkler system control assemblies. The drawing shows the main riser pipe connection linked to the zone control valve assembly that regulates water flow to the sprinkler system. Key components in the layout include the control valve, OS, and Y type with a supervisory switch, which allows monitoring through the fire alarm control panel. A pressure gauge is installed on the mechanical tee connection to measure water pressure within the fire sprinkler line. The drawing also includes a water flow switch connected to the alarm system to detect sprinkler water movement and activate the fire alarm control panel during emergency conditions. Victaulic fittings are shown connecting pipe sections to ensure secure and flexible pipeline assembly.
