    WB350 - WaterBug Sensor with Chirper

    The WaterBug WB350 is a water detection device ideal for computer rooms, document storage areas, warehouses, sump pumps and basements. It operates on 12v battery and has a form C relay output that can be connected to alarm panels, bells, dialers, etc. WaterBug sensors activate the alarm when a conductive bridge is formed between 2 contacts. Low Battery Indication: The WB-350 will trip the open collector output and give an audible warning if battery voltage runs low.

    The unit can monitor up to as many as six sensors up to a hundred feet away, depending on the wire used. Each sensor has surface contacts that will detect the first appearance of water forming a film on the floor. The sensor will not alarm due to condensation or high humidity.

    One standard surface sensor is included with the unit.

    Ideal For:

    • Residential or Vacation Homes
    • Basement Sump Pumps
    • Commercial Buildings
    • Office and Computer Areas
    • Unattended Buildings
