| An extremely loud piezo electric buzzer in a cream housing. Removing the back carefully with a screwdriver reveals screw terminal connections for the positive and negative DC power supply. A further three screw terminals if left open circuit make the buzzer emit a continuous tone. If screws 1 and 2 are connected together the buzzer emits a pulse tone and if screws 1 and 3 are connected together the buzzer emits a siren-like sound.Resonant frequency: |
