Safeguarding HVAC environments from condensate overflow buildup, the line of low-voltage flood prevention switches (FPS) can be used in commercial and residential applications. With tee, elbow, and bracket models available with multiple fittings to accommodate any application, each FPS model is simple to install, easy to service, and extremely reliable, said the company. At the heart of the technology is an integral magnetic reed switch. If a clogged a/c condensate drain causes the water level in the main or auxiliary drain pipe to rise, the FPS shuts off the system, preventing any possible overflow that could damage floors, walls, or ceilings. The switches can be installed on either primary or auxiliary drain plugs and are easily accessible for service. The flexible switch is available in red- or yellow-wire connection options.
