The PVC enclosure measures only 4×4 inches.Nevertheless, if a screaming tone is required, this will do it. For that reason we often get requests for a volume muffler to reduce the volume. This is a loud volume, comparable to most smoke detectors. Piezoelectric sounders are sound components which generate sound suitable for use as input signals (including multi-tone, melody and so forth) without built-in oscillation circuits. To compare, our standard buzzers are 103dB at the same 2 feet. Piezoelectric Sounders / Buzzers are sound components prepared by incorporating a piezoelectric vibration plate in a plastic case (resonator). The siren alarm piezo buzzer can be substituted for our standard buzzers on any of our products. See more information in the tab below “sound pressure”. It will cause your eyes to water and your eardrums to hurt and a distance of two feet. Since this Siren Buzzer SA-1 is painfully loud, consideration must be given to the placement and use of this device. The piezo siren comes standard with 10 ft.of cable so the siren can be mounted up high to broadcast the sound over a wider area). Because the SPL is 110dB at two feet distance we provide the siren buzzer in a separate enclosure from the pushbutton enclosure so as not to expose an operator to overly loud sound levels at arm’s reach. The model SA-1 piezo buzzer is EXTREMELY LOUD.

Audible signals from Auer Signal are available worldwideĪuer Signal signaling devices are manufactured in the south of Vienna, Austria. The specified sound pressure level of our audible signaling devices was measured in an echo-free sound chamber at a distance of 1 meter. The recommended sound frequency should be between 3 Hz. The frequency at which the signal is at its loudest should be as far away as possible from the frequency of the ambient noise. For audible signal devices, Auer Signal recommends a sound pressure level at least 15 dB higher than the ambient level. Environmental influences such as humidity, wind direction or weather conditionsĮspecially in the industrial sector, the effectiveness of an audible signal is strongly influenced by loud ambient noise generated by machines.The efficiency of an audible signal device is influenced by several factors and must be assessed individually depending on the field of application. The volume of Auer Signal’s audible signaling devices ranges between 60 dB and 127 dB. Our audible signaling devices are divided into the following three categories: Our top models achieve a sound pressure of up to 127 dB, are impact resistant (IK09) and suitable for use in extreme conditions (IP66). This gives you the ability to choose the right model for your needs from our powerful, robust and durable sirens. In our wide range of audible signal devices, you can find models for all applications. Its the same principle that you used in Project 7 when creating a pulsating lamp via a sine wave, but this time you replace the LED with a piezo sounder or piezo disc. Powerful audible signal devices for a better signalizationĪuer Signal offers state-of-the-art signaling devices, which are developed and manufactured in Vienna. By connecting a piezo sounder to a digital output pin, you can create a wailing alarm sound. The signal is given by one tone, several tones or a certain tone sequence. PIEZO SOUNDER WITH BUILT-IN CIRCUIT: BRP3922L-24-CT3: 38.6 mm: 22. They are generally used to signal faults or dangerous situations acoustically. Especially when there is no permanent visual contact between workers and the signaling device, audible signals are used. Application examples can be found in mechanical engineering, automation, special vehicles and cranes. Multi-tone alarm sounders, piezo buzzers and alarm horns are used in a variety of industries. The areas of application of audible signal devices are highly versatile.
