FCS-LWM-1 Linear heat detector

FCS-LWM-1 Linear heat detector

  • Usable in constricted spaces and under extreme environmental conditions
  • Usable in Ex-zones 1,2, 21, 22
  • Resistant to mechanical and chemical influences, corrosion, humidity and dust
  • Usable for DIN EN 54-5:2000 classes A1, A2, B, C
  • Simple installation and initial set-up
  • Minimal maintenance costs through continual self-monitoring of the sensor cable
  • Configurable response temperature
  • Test key for maintenance (simulates alarm and malfunction).

The FCS‑LWM‑1 is a Linear Heat Detector for detecting fire. Its functionality is based on the change in resistance of an electrical conductor caused by a rise in temperature.
