Wireless outdoor dusk and temperature detector

ADD-200 detects changes of light intensity (dusk detector) and temperature (temperature detector). It is designed to work within the ABAX 2 two-way wireless system. The detector is supported by the ACU-220 and ACU-280 controllers and the ARU-200 radio signal repeater.

  • dusk detector:
    • light intensity measurement in the range of 2 lx and 250 lx
    • option to select one of 16 detection thresholds
    • immunity to short and accidental changes of light intensity
  • temperature detector:
    • temperature measurement in the range of -30°C and +70°C
    • programmable temperature threshold
  • encrypted two-way radio communication in the 868 MHz (AES standard)
  • transmission channel diversity – automatic selection of the one of 4 channels that will enable transmission without interference with other signals in the 868 MHz frequency band
  • radio communication range in open area: up to 2000 m (with ACU-220) / up to 1600 m (with ACU-280)
  • remote update of detector firmware
  • remote configuration
  • LED indicator
  • “ECO” option for longer battery life
  • battery status control
  • weatherproof enclosure of high mechanical strength
