Product overview Active piezo electronic buzzer alarm with continuous tone. Integrated sounder design delivers stable performance and long service life in a compact ABS housing. Ready to use with a built in drive circuit. Simple two wire pigtail connection lets you power the unit directly from any DC supply between 3 and 24 volts. Key specifications Material: ABS Type: Active piezo electronic buzzer alarm, continuous sound Working voltage: DC 3 to 24 V Rated voltage: DC 12 V Maximum rated current: 12 mA Minimum sound output: 85 dB Response frequency: approximately 3300 Hz with a tolerance of 500 Hz Wiring: 2wire pigtails, integrated drive circuit for direct DC operation Why choose this buzzer Wide voltage compatibility: Operates from lowvoltage supplies up to 24 V, so it fits a broad range of systems without additional drivers. Low current draw: Maximum 12 mA keeps power consumption minimal, useful for battery powered or energy sensitive equipment. Clear, attentiongetting tone: Minimum 85 dB output and a response frequency centered near 3300 Hz make the buzzer effective for alerts and notifications. Durable construction: ABS housing provides a practical balance of strength and lightweight design for reliable everyday use. Easy installation: Twowire pigtails and a complete internal drive circuit eliminate the need for external driver components, reducing installation time. Performance and compatibility Function: Produces a continuous audible alert suitable for alarms, status indicators, and user notifications. Compatibility: Works with a wide variety of DCpowered devices and control systems that accept a simple twowire audible indicator. Mounting: Concise form factor and straightforward wiring allow mounting near buttons, indicator lights, or control panels to enhance user awareness. Typical applications Security and alarm panels: Provides a reliable audible alert for intrusion, fault, or tamper conditions. Industrial and control equipment: Acts as a status or fault indicator on machinery, control cabinets, and test fixtures. Consumer and commercial devices: Suitable for vending machines, kiosks, access control units, and appliance indicators where a continuous audible signal is required. Installation notes Connect the two pigtail wires to any DC power source within the 3 to 24 V range. Polarity must match the device wiring. No external driver circuit is required thanks to the built in drive electronics. Ensure the buzzer is mounted where sound can be heard clearly and where the ABS housing will not be exposed to conditions outside its intended use. This active piezo buzzer provides a straightforward, reliable solution for adding a continuous audible alert to a wide range of DC powered devices.
