Valve Groups
A Sprinkler Valve Group can be contained within a heavy duty plastic lockable box, or simply mounted on a board/wall, depending on the location of the Valve Group. The valve group consists of:
- Mains Water Inlet: size depending on the flow rate required by the system.
- Backflow Prevention Valve: ensures that water can not flow back into the mains water supply
- Sprinkler Isolation Valve: Isolates water to the system.
- Flow Switch: When a sprinkler is activated the flow of water operates a flow switch which then sends an electrical signal to the alarm control panel, see ‘Sprinkler Alarms’ page.
- Pressure Gauge: Measures the incoming water pressure.
- Drain & Test Valve: Used to drain and test the system.
