System benefits:


  • Optimally matched to the ES Line system
  • With multisensor detectors for the detection of all fires, even under the most difficult operating conditions
  • Up to 30 detectors per detection group

Reliable detection:


  • Uniform response sensitivity of the detector for all different types of fire for the multisensor detectors
  • Large distance between signal and interference magnitudes due to special sensor and electronics design for suppressing electromagnetic influences
  • Automatic adaptation to varying environmental influences
  • Electronic compensation also called drift-compensation of long-term influences of contamination or ageing

Reliable false alarm suppression:


  • High reliability against false alarms by temporal evaluation of different sensor criteria, with built-in insect screen and sealed against rear airflow entry
  • Exclusion of signal forms not typical of fires through special filter algorithms
  • Automatic self-monitoring of the detector electronics
  • Automatic self-monitoring of sensors for function and condition



  • Designation of the heat detector by a black ring on the light pipe
  • Hours of operation, alarm and fault counter in each detector
  • Operation data retrieval of all detectors of a group with standard service PC and field bus interface
  • Detector LED for alarm display and as an identification display in the service (for maintenance with 8000 tools)

Wide range of accessories:


  • Standard socket and relay base
  • Socket adapter for ceiling installation
  • Dust caps optional for fire detectors and detector base
  • Kit for suspended mounting

12 months warranty
