TRUNK MAIN PRESSURE ALARM

EN 12845 requires the trunk main in a fire sprinkler system to be monitored, if monitoring is specified/ required.

This product enables the signal to be tested without draining pressure from the trunk main. The signal can be tested and checked using only a few ml of water and not starting the fire pumps. The product has a non return valve in parallel with the isolation valve so it will sense a pressure drop even if the inlet valve is accidentaly left closed.

  • Failsafe Operation
  • Test/monitor the trunk main for low pressure
  • Minimal water useage
  • No need to start fire pumps
  • Tiny size allows flexibility of location
  • Simple to comply with EN12845
