Fire Detection & Suppression

Grain Drier Fire Detection

When correctly positioned and functioning, the Perry Fire Detection System can help provide early warning of a fire, helping to reduce potential damage to the drier. It is for use to detect fire within a grain drier drying column.

The Perry Fire Detection system is covered by patent application number GB1816756.9.

Key Points

  • The system uses a Digital Linear Heat Detection Cable clamped to the grain column to detect excessive heat.
  • The cable is clamped to the zone outlet panels in the exhaust plenum.
  • The Digital Linear Heat Detection Cable (LHDC) is a twisted pair twin core cable. When the trigger temperature of the LHDC is reached the heat reactive polymer causes the cores to connect and a Fire alarm is registered.
  • The Digital Linear Heat Detection Cables are wired to LDM-519-DDL monitor units.
  • When a fire alarm occurs, the LDM-519-DDL monitor unit automatically determines the distance to the point of operation and displays this by means of the LCD.
  • The fire alarm triggers a drier remote emergency stop. The drier stops all functions. The drier fans are stopped to prevent airflow from fanning a fire within the drier.
  • The LDM-519-DDL monitor also monitors the linear heat detection cable for faults. If a cable fault is detected, a drier remote shutdown is triggered, causing the drier to stop drying, run the fans for 30 minutes to cool the drier and then stop.
