VESDA LASERFOCUS VLF-250

  • Model: Honeywell

Active stand-alone detection system based on laser technology for the early detection of fires in small areas. 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.

Part-No.: VLF-250
Approval: VdS

Features:

  • Plug & play function (simple installation and commissioning)
  • Laser based smoke detection
  • Programmable alarm threshold value
  • Two-level air filtering
  • 10 digit integrated bargraph display
  • Integrated debugging function
  • Event memory for up to 18,000 events
  • Relay output: 3 changeover relays
  • Actuation and resetting is carried out via the esserbus transponder (Part No. 808623) during loop operation
  • Stand-alone system
