Warning Buzzer 

3 – 12 Vdc Operation 

Metal Cased Marked 6Vdc 

High Output, very shrill tone with a small slotted head screw tone adjust to fine tune.

Ideal as an inexpensive, easily installed warning device should a door or cabinet or display case be opened.

Be warned !! the tone is extremely shrill and unpleasant

 As an alarm, if a display case is being opened when it shouldn’t the culprit is likely to jump a mile.

To install, all that would be required is a 3 -12Vdc power source (battery or mains adapter – see our shop for 6vdc, 12vdc adapters) and a simple contact switch – wired so that when the door or cabinet is opened the circuit is closed and the alarm sounds.


Diameter 40mm

Depth 15mm
