Overview:

  • The FDO500 digital optical smoke detector with microprocessor and short-circuit isolator offers the highest reliability and accuracy for smoke detection based on the Tyndall effect. A specific algorithm supervises the smoke density by filtering out false alarms, performs calculation and storage of the drift compensation reference value, which is updated exclusively by command from the central unit. FDO500 automatically stores, in its nonvolatile memory, the previous thirty measurements and the 30 measurements following an alarm condition. These measurements can be displayed, in graphical or textual form, on the central unit's display. This feature is very important for retrospectively analyzing the condition of the detector before and after the alarm condition has been detected. The two-color LED, in operating conditions, indicates the detector status while, in service mode, it can be used to display the detector address via a function activated by the control panel.

     

Advantages:

  • Complete with self-learning circuit and short-circuit isolator
  • Smoke detectors operate on the principle of light scattering caused by smoke particles in the air
  • The detector has the function of automatic gain control; a microcontroller calculates the reading compensation to maintain a constant sensitivity over time, correcting for any increase in level caused by dust settling inside the analysis chamber
  • Smoke detectors should be installed in places where there are no air currents that could divert the flow of particles produced by combustion, and in places where normal activities carried out do not produce fires of gaseous materials
  • Supply voltage: 20VDC (voltage modulated from -15% to + 10%)
  • Average absorption at rest: 250 uA@20Vdc
  • Absorption in alarm: 2mA@20Vdc Two-color LED: red alarm - green normal operation
  • Max. relative humidity: 93%
  • Operating temperature: 0 to 50°C
  • Weight: 70g
  • Dimensions: ø 90 x 31 (H) mm
  • Certified EN 54 part 7 and 17 (1293-CPD-0138)
