Flash Buzzer AD16-22SM/R31/AC220V is an industrial-grade flash buzzer that integrates sound and light alarm functions. It is widely used in power systems, automation control, fire alarms, mechanical equipment and other fields. This product uses a dual warning method of high-frequency flash and high-decibel buzzer to ensure the rapid transmission of alarm signals in complex environments and improve safety response efficiency. Its design complies with the International Electrotechnical Commission (IEC) standard, supports AC220V wide voltage input, has strong adaptability, and stable and reliable performance.

Product Features

1. Sound and light integrated design

- Flash module: built-in high-brightness LED lamp beads, supports multi-frequency flashing mode (default frequency 60 times/minute), red light and yellow light optional (default red), strong penetration, and visual distance of more than 50 meters.

- Buzzer module: piezoelectric ceramic sounding element, output volume of 85-95dB (1 meter distance), adjustable sound frequency (default 2.8kHz), suitable for noisy environment.

2. Wide voltage adaptation

- Support AC220V±15% voltage input, adapt to power grid fluctuations, built-in overvoltage protection circuit to ensure long-term stable operation of the equipment.

3. Industrial-grade protection

- The shell is made of flame-retardant ABS material, protection level IP65, dustproof, waterproof, corrosion-resistant, and can work in an environment of -20℃ to +70℃.

4. Easy installation

- Provide panel embedded installation or guide rail fixing method, standard M4 screw hole position, adapt to the standard control cabinet opening size (Φ22mm).

Application scenario

- Industrial equipment: machine tool fault alarm, assembly line abnormal prompt.

- Power system: distribution cabinet overload, short circuit warning.

- Security and fire protection: fire alarm, emergency evacuation guidance.

- Traffic facilities: gate status prompt, tunnel safety warning.

Maintenance and troubleshooting

1. Daily maintenance

- Clean the surface dust regularly to avoid blocking the light source and sound hole.

- Check whether the terminal is loose to ensure good electrical contact.

2. Common faults

- No light and no sound: Check whether the power input and control signal are normal.

- Only flashing without sound: Check the wiring of the buzzer module or replace the sound element.

- Volume reduction: Clean the foreign matter in the sound hole or contact after-sales inspection.

Precautions

1. Flash Buzzer AD16-22SM/R31/AC220V is strictly forbidden to overload and avoid being in a humid or high temperature environment for a long time.

2. Ensure that the equipment is grounded during installation to prevent static interference.

3. Non-professionals should not disassemble the internal circuit. If repair is required, please contact an authorized service provider.
