I wanted to use it for the buzzer sound of the car backgard, but the sound was large and it was inappropriate for the intended use with "pea" continuous sound of the common alarm. I wanted a concrete explanation of the sound in the product explanation.
I thought about buying an answer back siren, but since the installation location is narrow, I bought a buzzer. I wore it to COMTEK keyless, so wiring was easy. It was a bit surprising that the sound was not a buzzer, but a sound that did not differ from siren. When using keyless, people around turned around. (Lol)
