Surprise! A Siren You Can Hear!

This little electronic buzzer didn't disappoint. The sound is loud enough to grab anyone's attention and the continuous tone makes sure it gets noticed. The installation was smooth and the overall build quality is great considering the price. The only con is that it only operates on 24V, which may not be suitable for all electronics. Nevertheless, it's a great addition to any security system.

Pros
  • Produces a loud and clear sound that is easy to hear.
Cons
  • The continuous sound may become annoying or disruptive in certain settings.

Simple buzzer for teaching children

These buzzers were bought as an experiment kit to teach children about electrical circuits. Create a simple battery, switch, relay and buzzer and ask the kids to follow the pattern to make it buzz. Children will learn how to read an electrical circuit and when connected correctly, it will power the buzzer. Great use of components to teach kids how to wire circuits.

Pros
  • Electronics
Cons
  • Fits

Great product at a low price.

This product is as advertised. Mini alarm that can use different voltages and consumes around 30mA. Alarm every bit 80db. I use it with a 9 volt battery and a pressure switch as an alarm indicating that my air compressor's air pressure switch failed to turn back on at the correct pressure. I will also hook up a couple of these to my hatches on my boat to alert me if someone opens the hatch, moves the outboard or dinghy while we sleep.

Pros
  • Security and Surveillance
Cons
  • Quick Start Guide
