Fire Barrier Code 222S

The Conflow Code 222S - Extended Water Fire Barrier is used to contain and prevent the spread of fire in underground roadways.

The barrier consists of a structure of 2" metal pipes, which are usually situated towards the roof of a roadway in a central position. Special sprays are sited at regular intervals along the length of the pipe so that, when energised, they create a curtain of water, which acts as a fire barrier across the roadway section.

The barrier is energised using a pilot operated weighted lever valve, which is triggered by temperature sensitive links.

Typical Applications

  • Barriers are installed in main roadways ahead of potential fire sources and downstream of the flow of ventilation in all types of underground mines
  • Shorter barriers are also fitted locally around conveyor drives and ventilation fans

Features

  • 2" main feed pipework
  • Barriers from 14m up to 55m in 2.7m lengths
  • Spray sizes 3/32" or 1/16"
  • Complete roadway coverage by elbow spray housings
  • Weighted lever valve set to trigger @ 57°C
