Flood Buzz™ Pro-02 is a water leak alarm that was created specifically for use in condensate pans. The alarm is designed to allow moisture to collect in the pan up to a depth of 1⁄8-inch. Once water reaches 1⁄8 inch, a 110-dB alarm alerts a user that the water in the pan is not exiting and that a possible flood condition exists. It sounds an alert when an air conditioner’s condensate pan is blocked. Contractors still get the service call to clear the pan, but the customer doesn’t suffer the flooding and water damage. The unit includes an internal battery and sounds an alert when water touches the two prongs on the bottom of the product.
