Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Intensity Alert System: Generates a 120dB piercing siren or buzzer sound, ideal for door alarms, security systems, and emergency signaling.
  • Continuous Operation: Designed for uninterrupted use, ensuring reliable alerts in critical scenarios like fire alarms or intrusion detection.

Key features

  • 1. High-Powered Sound Output

    • With a 120dB output, you can ensure alerts are heard over long distances, surpassing standard 90dB buzzers*. This makes it ideal for critical applications like door alarms and emergency sirens.

  • 2. Advanced Piezo Technology

    • With piezo technology, you can achieve energy-efficient operation while maintaining durability, outperforming bulkier electromagnetic alternatives*. The lightweight plastic construction ensures reliability in harsh environments.

  • 3. Customizable Frequency & Volume

    • With adjustable frequency and volume settings, you can tailor alerts to specific needs (e.g., low-frequency alarms for homes or high-pitched sirens for commercial use), unlike fixed-output models*.

  • 4. Continuous Operation for 24/7 Reliability

    • With continuous operation capability, you can ensure uninterrupted alerts for security systems or industrial applications, ideal for commercial and residential use*.

  • 5. Compact Design for Easy Integration

    • With its cylindrical, lightweight design, you can seamlessly integrate the buzzer into tight spaces or complex devices, outperforming bulkier competitors*. The red/black wiring simplifies installation.

Supplier's note

  1. Technical Breakthroughs:

    • The Pro Model’s 120dB output (20% louder than industry benchmarks) ensures alerts cut through noise in factories or crowds.
    • Expanded voltage compatibility (6–24V) in the Pro Model reduces the need for voltage regulators in mixed-power systems.
    • Enhanced -30°C to 70°C temperature range allows deployment in extreme environments like outdoor security systems.

  2. Optimal Version Selection:

    • Pro Model: Ideal for industrial or high-noise applications (e.g., factory alarms) where extreme loudness and temperature resilience are critical.
    • Advanced Model: Best for mid-range systems like home security or commercial door alarms needing broader voltage support.
    • Base Model: Suitable for simple, fixed-voltage applications like small appliances or low-power sensors.

With the Pro Model’s triple-layered durability and 120dB output, users can ensure alerts are both heard and reliable. Pair its wide voltage range with outdoor installations to eliminate power conversion complexities.
