Review on WEICHUANG Active Electronic Buzzer Continous by Adam Ross
Loud enough for horns and sirens
Connected to a test lamp I use on airplanes so I don't have to bend down to see the light. This is a 28V DC system so I soldered a 1kΩ resistor in series to drop the voltage. Works perfectly. Similar to the diode on your Fluke test tool, only louder.
- SOUND OUTPUT: The horn is 100dB at 12V DC at 30cm, you can wait for your desired volume by adjusting the voltage. Response Frequency: 3 ± 500 Hz
- Something else
