Flood Buzz’s Pro-02 is a water leak alarm created specifically for use in condensate pans. It is designed to allow moisture to collect in the pan up to a depth of 1/8”. Once water reaches 1/8”, the unit sounds a 110 dB alarm alerting that the water in the pan is not exiting and that a possible flood condition exists. The 2 3/4” high by 1 7/8” diameter alarm can be personalized with the contractor’s contact information on the unit. The internal battery has a three-year lifespan. Flood Buzz.
