Optical Smoke Detector Detect ES with relay contact, 48 V DC operation


The threshold value detector with relay contact 800361.10 comprises an optical smoke detector 800371 from the ES Detect series and a detector base 805592 which enables a direct connection to a 48 V DC power supply. The detector therefore does not need to be operated in connection with a fire alarm control panel. If the detector detects a fire alarm, a floating relay contact activates to transmit the alarm. The relay contact is normally open (NO) by default, but can also be configured as normally closed (NC) with a solder strap on the circuit board base. A typical use for this detector is to monitor mobile communication stations, e.g. BTS base transceiver stations.
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 of long-term influences of contamination or aging

Reliable false alarm suppression:
  • High reliability against false alarms by temporal evaluation of different sensor criteria
  • 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
