Maretron Bilge High Water Detector - BHW100

The BHW100 Bilge High Water Detector provide immediate response to rising water, sending a signal to the Maretron SIM100 Switch Indicator Module.

Features:

• Accessory for SIM100 Switch Indicator Module
• Will indicate high water by illuminating the red LED and sending a signal to the Maretron Switch Indicator Module (SIM100)
• Molded-in "Target" on the side of the unit is visible

Installation Instructions BHW100 Bilge High Water Detector

• The BHW100 sensor has a target molded into the plastic enclosure (opposite the side with the Maretron label)
• The target should be exposed so that when the water rises above the middle of the target, the BHW100 will indicate high water by illuminating the red LED and sending a signal to the Maretron Switch Indicator Module (SIM100)
• The BHW100 is mounted to a vertical wall in the bilge with the label pointed in towards the wall and the target facing outward into the bilge
• The BHW100 always act immediately to rising water. However, there can be some delay to receding water while the water evaporates off the face of the BHW100
• Here are some tips to make the BHW100 act quickly to receding water:
  • 1) Mount the BHW100 to a vertical wall in the horizontally direction as shown in the attached instruction sheet. This helps water quickly run off the BHW100
  • 2) Cover the mounting screws and metal mounting sleeves with some silicone
    • Water bridging between the target and mounting screws makes the BHW100 think it's still under water
    • Eventually the water evaporates and the BHW100 shuts off
    • If you prevent the un-evaporated water from bridging between the target and screws, you will get the BHW100 to react much quicker to the receding water
