Protect Your Home/Business From Flooding!

Don't let water damage ruin your home or business! Add the Winland Wireless WaterBug Sensor in rooms that are susceptible to flooding such as the bathroom, laundry room, kitchen, and basement. This sensor uses a wireless connection and is available in 345 MHz or 319.5 MHz frequency options. It's compatible with any wireless alarm system that can receive either a 345 MHz or 319.5 MHz frequency, respectively. It has been tested with Nortek Security Control and Simon XTi systems.

  • Detects water when liquid makes contact with the probe
  • Requires two positive checks for a valid alarm
  • No false alarms due to condensation or humidity
  • Constantly checks for water
  • Easy surface-mount installation

The Wireless WaterBug Sensor comes with a transmitter and surface probe. The transmitter mounts on a wall or other flat vertical surface while the surface probe can be mounted on the floor or on the wall for rising water levels. The sensor probe has 2 contacts. A film of water forming a bridge between these contacts will activate the WaterBug alarm. And even though the sensor probe is highly sensitive, it will not be fooled by condensation or high humidity.

The sensor is ideal for basement sump pump and drain areas, storage facilities, computer rooms, warehouses, laundry rooms, critical labs, residential and commercial kitchens, and more.
