It alerts you with a loud, distinct beep the moment your tank reaches full capacity. Built with advanced anti-scaling technology , the included maintenance-free sensors provide consistent performance for years without degradation. By eliminating repeated overflows, this device prevents expensive structural damage to your home’s roof and walls. Ultimately, it serves as a cost-effective solution that saves significant money on water bills while offering long-term peace of mind. The Science Behind the SensaSwitch Advantage Why a transformer-based power supply? Transformers provide total electrical isolation from the main grid, ensuring maximum user safety. Unlike cheap electronic alternatives that compromise on protection, SensaSwitch prioritizes a shock-proof design. What is anti-scaling circuitry? It uses low-voltage signals to prevent mineral buildup on sensors. While battery-powered devices attract salt through high direct current, SensaSwitch stays clean, eliminating the need for periodic maintenance. Why do the sensors matter? Only high-grade stainless steel survives years of heat and humidity without corroding. While ordinary metals like copper or aluminum fail, SensaSwitch uses premium steel probes to ensure permanent conductivity and reliability. How to connect input power? Plug & Socket Connection While connecting the SensaSwitch-OBS via a standard plug and socket is the simplest setup, it requires you to manually toggle the alarm each time you run your pump. To eliminate the hassle of switching the alarm on and off separately, we recommend integrating the power input directly with your pump’s starter. This ensures the alarm automatically activates and deactivates alongside your motor for a seamless, hands-free experience. Motor Power Supply Connection Connecting the alarm input directly to the pump motor supply is the most efficient setup for systems operated by a manual switch. This configuration ensures the alarm automatically powers on with the pump and shuts off the moment you turn the motor off. By synchronizing the two, you eliminate the need for manual operation, extend the device's lifespan, and reduce unnecessary electricity consumption. Motor Starter Output Connection For pumps operated via a starter box, such as submersible models, connect the alarm input to the R (Red) and B (Blue) output terminals. This integration ensures the alarm automatically synchronizes with the pump's operation. If you require further technical assistance with your wiring, please contact the SensaSwitch helpline. How to connect water sensors? For optimal performance, let the water sensors hang freely just below the overflow level so they can be fully immersed. There is no need to permanently fix the sensors in place; allowing them to hang naturally ensures accurate detection and easy installation. Maintain a vertical gap of 1–2 inches between the sensors to prevent them from touching. This spacing is crucial for accuracy, as it prevents false alarms caused by moisture or high humidity transmitting signals across the sensor surfaces. These water sensors are designed for use in raw, unprocessed water such as ground, tap, or sea water. If you intend to monitor other liquids, such as processed water or storm water, please contact the SensaSwitch helpline for specialized guidance. Important Information & Specifications Install alarm device at a place which is safe from rain and water splashes. Place water sensors in water tank near full level. Connect water sensors with alarm by using extra wire. Test by dipping water sensors in water.
