Unlike magnetic buzzers that have a narrow operating voltage of somewhere between one and 16 volts, piezo buzzers can typically operate anywhere between three and 250 volts. ![]() As a result, it produces an audible sound. So when certain piezoelectric materials are subjected to an alternating field of electricity, the piezo buzzer element - often a manmade piezoceramic material - stretches and compresses in sequence with the frequency of the current. They found that electricity could be generated when a mechanical pressure was applied to particular materials - and the inverse was true as well. The use of the piezo ceramic buzzer was discovered thanks to an inversion of the piezoelectricity principle that was discovered by Jacques and Pierre Curie back in 1880. Contact APC Today How to Use Piezoelectric Buzzers In addition, thanks to our state-of-the-art production facility, our delivery times are some of the fastest in the industry. Plus, since they can be mounted on circuit boards, they’re highly useful in a wide range of applications and assemblies.ĭespite different construction methods that affect the cost of piezo buzzers, all of our prices are highly competitive. Regardless of the model you choose, our piezo buzzers offer high sound outputs. Yet at the same time, depending on the piezo ceramic buzzer specifications, it’s also reliable and can be constructed in a wide range of sizes that work across varying frequencies to produce different sound outputs.įor instance, at APC International, Ltd., we offer piezo buzzers without signal generators, self-oscillating buzzers that have signal generators and even multi-tone sound generators - often used in alarms and sirens. It’s lightweight with a simple construction, and it’s typically a low-cost product. In simplest terms, a piezo buzzer is a type of electronic device that’s used to produce a tone, alarm or sound. ^^ Excluding tabs 27.5 ☐.5 w/ tabs (center to center) What Is A Piezo Buzzer? *** 4.0 kHz / 10 cm / 12 Vp-p square wave Rated Voltage: 12 VDC (KPT-1410: 12 Vp-p square wave) Remote engineer hold off - It is possible to disable the bell box tamper when a control panel is in the engineers menu.Values to be Determined by Customer and APC International.Engineer hold off facility - When first powered with the tamper switch open, the sounder will not activate.3mm Poly housing - Enables a panoramic strobe effect illuminating the full bell box.Siren cut-off timer - The cut off timer is defaulted to 15 minutes to meet industry regulations.Supplied with battery - Complete with a backup battery so that even in the event of an intruder sabotage, the bell box will still operate and protect the property.Revolving guide holes - Unique leveling mechanism including in-built spirit level and revolving guide holes.Universal triggering inputs - Can be connected to any output on a manufacturers control panel, positive applied, negative applied, positive removed, negative applied.In this situation, the siren will activate independently of the control panel. 3 Way tamper action - Activation from front, back, and power supply cut off ensures protection from sabotage attempts.Twin piezo -Twin piezo sounders with high decibel output. ![]()
