12V Active Buzzer – Loud Sound Alarm Module for Security and Alert Systems

The 12V Active Buzzer is a powerful and self-driven sound-emitting device that generates a continuous tone when powered with 12V DC. Unlike passive buzzers, this module includes a built-in oscillating circuit and does not require external frequency signals—simply connect power, and it produces a loud, clear alarm sound.

With its durable construction and high sound output, the 12V active buzzer is ideal for use in security systems, fire alarms, door indicators, industrial machines, and other alert-based applications.
