Review on 🔔 Sydien AC 110V 114dB Industrial Motor Alarm: Bell Horn Buzzer Siren—Powerful Sound Alert System by Dale Sundet

I purchased this item as part of an alarm system that will let us know if a submersible well pump is not keeping a 2500 gallon water tank full. I installed this device to turn on with a flashing light installed at the front of the store between two houses with a water system. A float valve was installed in the tank and set to activate when the water level falls more than 4 inches below the lower limit of the main float switch. So when the water level drops below 2000 gallons we get a message. This all happened after the submersible pump failed and we didn't know about it until both houses ran out of water (around 11pm of course). Red LED signal light All the circuits are rated for 110V just for convenience, but the current is very low so I was able to use the 6-wire 22ga sprinkler control cable I had for 30 feet to the install site. I started with this, not necessarily how it ended, but close to using a geared motor from an old item at about 2 RPM, a Korean War Air Force radio modified to make a camera, and a microswitch from a broken timer to turn on and the siren turned itself off after about 2-4 seconds d because the noise was deafening (I did all the tests with shooting headphones). The power indicator light is from another project and the switch is from a faulty starter battery/air pump.
