Review: Reliable - I have purchased this item on 19 th Aug 2020 and after delivering product I have called the owner (customer care) about installation and working. I remembered, owner said to me this will long last without trouble. I am writing this review in 2026. Really a solid product. 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 - Completely safe, uses transformer supply for foolproof insulation from mains - Completely maintenance free, no need for periodic cleaning of water sensors - Melody alarm sound level (75-85 decibel), fixed volume ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077WWQ63J | | Audible Noise | 80 Decibels | | Brand | SensaSwitch | | Built-In Media | 1 alarm device, 2 water sensors | | Color | White | | Colour | White | | Compatible Devices | Smartphone | | Compatible devices | Smartphone | | Control Method | Touch | | Customer Reviews | 4.2 out of 5 stars 5,123 Reviews | | Item Dimensions L x W x H | 7.5L x 6W x 12.5H centimeters | | Item Type Name | water tank overflow alarm | | Item Weight | 325 Grams | | Manufacturer | SENSASWITCH ELECTRONIC SYSTEMS | | Maximum Range | 300 Feet | | Mfr Part Number | SensaSwitch-OCA | | Model Number | SensaSwitch-OCA | | Mounting Type | Wall Mount | | Number of Items | 1 | | Power Source | ac | | Power source | ac | | Product dimensions | 7.5L x 6W x 12.5H centimeters | | Sensor Technology | Anti-scaling | | Shape | Rectangular | | Size | standard | | Unit Count | 1 Set | | Voltage | 220 Volts (AC) | | Wattage | 1 watts | ## Images ![SensaSwitch Overflow Control Alarm with Water Sensor Set, Fixed Volume Musical Alarm, White Plastic, Model-OCA - Image 1](https://m.media-amazon.com/images/I/71za24wKd0L.jpg) ![SensaSwitch Overflow Control Alarm with Water Sensor Set, Fixed Volume Musical Alarm, White Plastic, Model-OCA - Image 2](https://m.media-amazon.com/images/I/71TZXUgtiNL.jpg) ![SensaSwitch Overflow Control Alarm with Water Sensor Set, Fixed Volume Musical Alarm, White Plastic, Model-OCA - Image 3](https://m.media-amazon.com/images/I/819aC5USqBL.jpg) ![SensaSwitch Overflow Control Alarm with Water Sensor Set, Fixed Volume Musical Alarm, White Plastic, Model-OCA - Image 4](https://m.media-amazon.com/images/I/71S4YOPM-YL.jpg) ![SensaSwitch Overflow Control Alarm with Water Sensor Set, Fixed Volume Musical Alarm, White Plastic, Model-OCA - Image 5](https://m.media-amazon.com/images/I/71KlgkxvH3L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable *by M***J on 17 April 2026* I have purchased this item on 19 th Aug 2020 and after delivering product I have called the owner (customer care) about installation and working.

After started using this product, this items performance is matching with the reviews given. This Overflow Control Alarm is easy to install with the circuit diagram furnished. This water overflow control alarm saves overflow of water and reduces Electricity bill . The alarm bill rings very promptly alerting for the switching off of the motor. Yes, the initial cost is slightly on higher side. But in long over run, worth buying it. I am using it since one month and it is working hassle free. One can opt for this model without thinking twice. Service support also seems to be good as per the reviews . Only drawback is there is no volume control for this model. ## Frequently Bought Together - SensaSwitch Water Tank Overflow Alarm Bell with Water Sensor, Model-OCA, Fixed Volume Musical Sound, White ABS Plastic - SensaSwitch - Raw Water Sensor Set, Two Water Detector Probes for Overflow Alarm - Goldmedal Liquid Water Alarm Bell (White) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/571168253-sensaswitch-overflow-control-alarm-with-water-sensor-set-fixed-volume](https://www.desertcart.no/products/571168253-sensaswitch-overflow-control-alarm-with-water-sensor-set-fixed-volume) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-13*
