Alarm Sounder
Hi, I have for sale a NEW Piezo Electronic Multi Tone warning Sounder / Beeper / Buzzer / Audible Alarm. It gives out a high frequency oscillating multi frequency sound that is intolerable to the human ear. If you combine this unit with a strobe light it is nearly impossible to remain within 5m or so as the balance mechanism in your ears is upset and the strobe light makes it very hard to walk normally let alone see items clearly. Voltage range - 7.5 to 15v Current (approx) - 200mA @ 12v I
