8. Troubleshooting

No Sound Output

• Check Power Connection: Verify that the DC24V power supply is correctly connected and actively supplying power. Confirm proper polarity (+ to +, - to -).
• Verify Voltage: Ensure that the input voltage is precisely DC24V. Incorrect voltage can prevent the device from operating.
• Inspect Wiring: Examine all wiring for any loose connections, breaks, or damage between the power source and the buzzer.
• Obstructions: Confirm that the speaker grille is not blocked by any foreign objects.

Sound is Too Low or Distorted
