Flood detector LD-12 (water spot detection)

Czech version

English version

The LD-12 water flood detector is designed for spot detection of water leaks or detecting excessively high water level. Water detector can be connected to a dry-contact digital input (Poseidon, Damocles, I/O Controller). 12V power, transistor at the output.

The detector indicates a water flood in a room (e.g. basements, bathrooms). The LD-12 detector can be connected to dry-contact inputs (DI - Digital Input). The probe has a 3mm mounting hole for easier installation.

  • Red wire: +12V
  • Black wire: GND
  • Blue wire: Water detection (GND when flooded)
  • Yellow wire: Water detection (GND when not flooded)
