Powered safely by a low-voltage copper coil transformer, it offers easy installation and a 1-year manufacturer warranty, ensuring long-term protection against water damage and wastage for your home. ## Description Product Description Advanced Technology for Reliable Water Level Detection The system features Anti-Scaling Technology that ensures sensors remain free from salt deposits, even in areas with very hard water. With a Maintenance Free Sensor design using high-grade stainless steel probes, the device continues working reliably for years without requiring any upkeep. Low Voltage Operation ensures completely safe functioning through a sensor signal and circuit powered by a copper coil transformer, providing peace of mind during everyday use. These features work together to deliver consistent performance whilst helping you conserve water and protect your property from overflow-related concerns. Key Reasons To Buy SensaSwitch 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, brass 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-OCA 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, error-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.

Still it works good. Thanks Review: Good product, Speaker can be improved and Light can be added - In our society we have purchased more than 15 Water flow Alarm. It works really great with good Sound. However after roughly after 1.5 years speakers stop working in several pieces since it did not have any Status light for Tank Full it is very difficult to know speaker stopped working unless tanks get overflowed. I request Manufacturer to Add a status Green Light as well and improve Speaker quality. Since we had some pieces where only speaker was not working and rest circuit was working I added a Status Green Led myself also I updated the speaker as shown in the video. Do note I am an electronics enthusiast guy so I opened it myself but I do not suggest anyone to open it. ## Features - Prevents Water Damage: Protects roofs and walls from damage caused by repeated tank overflows - Prevents Water Wastage: Helps you avoid water tank overflows and conserve water resources - Fully Safe Operation: Works on a completely safe low voltage sensor signal and circuit powered by copper coil transformer ensuring full safety during operation - Reliable Performance: Built around advanced anti-scaling circuitry that keeps water sensors free from any salt deposits on sensor probes even in very hard waters - Zero Maintenance Design: Water sensors feature high grade stainless steel probes which are not affected by high heat and humidity in water tank and work reliably over years without maintenance - One Year Warranty Coverage: Manufacturer warranty from date of invoice ensures quality and reliability by saving water and protecting your home rooftops and walls from overflowing water - Easy Installation Process: Only basic electrical knowledge and tools needed to setup the water overflow alarm system - Musical Alarm Alert: Alerts you with a pleasant musical alarm when water tank reaches full level, no human voice ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077WWQ63J | | Audible Noise | 80 Decibels | | Best Sellers Rank | #2,833 in Home Improvement ( See Top 100 in Home Improvement ) #9 in Water Detectors | | Brand | SensaSwitch | | Built-In Media | 1 alarm device, 2 water sensors | | Colour | white | | Compatible Devices | Smartphone | | Control Method | Voice | | Country of Origin | India | | Customer Reviews | 4.2 out of 5 stars 5,214 Reviews | | Item Dimensions L x W x H | 7.5L x 6W x 12.5H Centimeters | | Item Type Name | water tank overflow alarm bell | | Item Weight | 325 Grams | | Manufacturer | Call/Whatsapp - 9814055314 (9am-6pm, Mon-Sat) Email - contact@sensaswitch.co.in Website - www.sensaswitch.co.in, SENSASWITCH ELECTRONIC SYSTEMS | | Manufacturer Contact Information | Call/Whatsapp - 9814055314 (9am-6pm, Mon-Sat) Email - contact@sensaswitch.co.in Website - www.sensaswitch.co.in | | Manufacturer Warranty Description | One year warranty from date of invoice, by manufacturer, as repair/replacement of defective item, on defective item being presented to sensaswitch. | | Maximum Range | 300 Feet | | Mounting Type | Wall Mount | | Packer Contact Information | SENSASWITCH ELECTRONIC SYSTEMS 71 SHEKHPURA PATIALA PUNJAB 147002 INDIA | | Power Source | Corded Electric | | Product Dimensions | 7.5L x 6W x 12.5H Centimeters | | Sensor Technology | Anti-scaling, Conductivity Sensing, Maintenance Free | | Unit Count | 1 Set | | Voltage | 220 Volts (AC) | ## Product Details - **Colour:** White - **Brand:** SensaSwitch - **Power Source:** Corded Electric - **Compatible Devices:** Smartphone - **Product Dimensions:** 7.5L x 6W x 12.5H Centimeters ## Images ![SensaSwitch Water Tank Overflow Alarm Model-OCA with Water Sensor, Fixed Volume Musical Bell, 1 Year Warranty - Image 1](https://m.media-amazon.com/images/I/71za24wKd0L.jpg) ![SensaSwitch Water Tank Overflow Alarm Model-OCA with Water Sensor, Fixed Volume Musical Bell, 1 Year Warranty - Image 2](https://m.media-amazon.com/images/I/71TZXUgtiNL.jpg) ![SensaSwitch Water Tank Overflow Alarm Model-OCA with Water Sensor, Fixed Volume Musical Bell, 1 Year Warranty - Image 3](https://m.media-amazon.com/images/I/819aC5USqBL.jpg) ![SensaSwitch Water Tank Overflow Alarm Model-OCA with Water Sensor, Fixed Volume Musical Bell, 1 Year Warranty - Image 4](https://m.media-amazon.com/images/I/71S4YOPM-YL.jpg) ![SensaSwitch Water Tank Overflow Alarm Model-OCA with Water Sensor, Fixed Volume Musical Bell, 1 Year Warranty - Image 5](https://m.media-amazon.com/images/I/71KlgkxvH3L.jpg) ## Questions & Answers **Q: Does the package contain cables for the sensors and power? If yes, of how much length?** A: The package contains only overflow alarm device with a set of sensors. Generally input power cable (about 2 feet with device) needs no extension as device needs to installed near power source only. Sensor signal wire need to be extended as per site need, from alarm device to water tank. We recommend single pair .4mm copper signal wire for signal but any 2 core cable can be used as signal wire as signal strength is very low. **Q: Have waranty?** A: Yes, one year from invoice date **Q: This is complete set with wire sensor and other related accessories** A: There are three main parts of the system - 1) Alarm Unit 2) Water Sensor 3) Sensing Cable. The first two are packaged in box you buy from SensaSwitch. You will need to buy the third (sensing cable) as per your site need (as per distance of alarm unit from water tank). You can buy any two core wire as sensing cable but we recommend 0.4mm copper, one pair (two core) telephone signal wire. **Q: What kind of alarm does it produce? Music, announcement in hindi/english or buzzer?** A: Sir, our device produces a musical melody alarm with 75-85 decibel sound level, through a high quality speaker. Our alarm neither have human voice announcement nor have buzzer sound. To hear melody sound of our alarm you may check DEMO VIDEO of overflow control alarm at our website. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good and long lasting quality water tank alarm *by R***M on 21 February 2026* I am using this sensa switch product from the past 3 years.
