22mm Panel mount active buzzer (beeper) with flashing red indicator

This buzzer indicator LED light is designed for use in electrical systems, telecommunications equipment, machine tools, and other machinery requiring status indication. It provides clear signal notifications such as operational status, warnings, and fault alerts.

The unit uses an LED light source known for its long service life and low energy consumption. Its concealed terminal design enhances safety and reliability.

During normal operation, the buzzer emits sound (a high pitched note) and the red indicator lights simultaneously. The alert sequence begins with one steady beep, followed by a repeating series of short beeps; similar to a Morse code pattern consisting of a single dash followed by an indefinite series of dots. This pattern continues until power to the buzzer is switched off.
