## 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.

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.

### ⭐⭐⭐⭐ Good product, Speaker can be improved and Light can be added
*by  on Reviewed in India 15 April 2023*

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.

### ⭐⭐⭐⭐⭐ Good and long lasting quality water tank alarm
