Wet Switch Flood Detector is a solid state control designed to help prevent flooding, damage to carpets, walls, furniture, ceilings, etc. that now has a built-in test and reset button for easier installation. Turns system off when detecting moisture due to condensate or drain leaks. 1 or 2 drops will cause Wet Switch to turn off a unit, alerting a serviceman to a moisture problem. A lit LED indicates the Wet Switch is activated and has turned the unit off, reset simply by drying the absorbent pad with a paper towel and pressing the reset switch.
Integral feet raise the hydrophilic pad and sensor array off the drain pan slightly to prevent nuisance tripping and pan corrosion (metal pans only) from interfering with the sensor array
High tech polymeric fiber quickly draws water into the sensor array using proven capillary technology and detects even a minimal amount of water drawn into the hydrophilic pad
Multiple unit connectivity allows for multiple wet switches to be connected in series to adequately cover large drain pan areas
Power supply to the wet switch is 24VAC, the standard power available on most air handler units, making hookup quick and easy since there is no need to run different power to the switch
Double throw relay allows for wiring to interrupt the system and to sound an alarm (by others) when moisture is detected
When the wet switch activates, it locks out the call for cool circuit on the air conditioner until the switch is manually reset preventing continuing damage in cases where the overflow water drains out of the pan, onto the surrounding ceiling
