Laser FOCUS VLF-500 - ESSER, multilingual

761500

Early fire detection system based on laser technology. The system is optimized for use in the following areas: air conditioned areas (e.g. data processing rooms), laboratories and clean rooms, rooms with valuable things (e.g. museum).

The actuation on the loop and the resetting function is carried out via the esserbus transponder (Part No. 808623).

Actuation on a conventional line is carried out via the same transponder. The device requires a separate voltage supply of 24 V DC.

  • Adjustable sensitivity from 0.005 % / m up to 20 % / m obscuration
  • 4 programmable alarm levels (alarm, pre-alarm, fire 1, fire 2)
  • All alarm levels can be assigned to a time window from 0 – 60 s to prevent false alarms
  • 2 fault levels (maintenance, fault)
  • 7 free configurable potential free contacts (30 V DC/1 A)
  • Monitoring of filter and air flow to support service
  • Event memory up to 18.000 entries
  • Day/night operation (different sensitivity levels)
  • Connection of up to 4 pipes per detector unit with an overall length of up to 200 m. It is possible to extend the overall length under consideration of the air transport time (100 s according to the VdS)
  • Auto learn function to determine the best sensitivity level (the system stays armed during the self learning algorithm)
  • Programmable with tools LRS 200 (Part No. 761504) / 210 (Part No. 761505) or with a PC and the PC-interface LRS 300 (Part No. 761506) and Windows© software (Part No. 797595) CD ROM with Software VConfig PRO and ASPIRE (these components are not supplied as standard)
  • It is possible to compensate the environmental conditions with a reference detector
  • Integration of up to 99 detector systems by the bus system “VESDAnet™”
  • The alarm, fault and operation status is shown on the front panel
  • Pipe configuration with “ASPIRE” software, with VConfig PRO and ASPIRE
  • Actuation and resetting is carried out via the esserbus transponder (Part No. 808623) during loop operation
