JOHNSON - BILGE ALERT high water alarm with Ultima Switch

Product details

The Bilge Alert system from JOHNSON uses a Mirus field effect detector cell, which produces a micro-electrical field that detects disruptions caused by water and fluids. When activated the sensor triggers a 100db piezo alarm and an LED light on the control panel. The detector cells are completely sealed, never in contact with the water, do not corrode and are not affected by oil or other foreign debris.
The alarm can be armed, tested and disabled with the unique 3-way switch.

  • No moving parts
  • Totally sealed
  • No mercury
  • Environmentally friendly
  • Compliant with ISO 8846
  • Available in 12 V and 24 V
