The module provides line monitoring for open or short circuits on the wiring connected to both the safe and hazardous areas.

Key Features:

  • Provides dual sounder circuits
  • Provides fault-monitored input
  • Interfaces between loop and I.S. sounders/beacons
  • Fully monitored for short-circuits
  • Requires 24 vdc external power supply
  • Also available as a DIN module
