Audible signalling equipment

Auer Signal offers a full range of audible signal devices for different kinds of industries delivering quality products since 1910. Here you can find audible signal devices for panel or surface mount, with volume from 65 db to 127 db for the loudest ones. We offer electronic sirens as well as alarm horns in various sizes, shapes and colours with degree of protection up to IP66.
Series A - the Mighty
    Series A is the largest and most comprehensive multi-tone sounder in four sizes with a square design. You will receive the series-A multi-tone sounders in sizes of 94 mm, 132 mm, 184 mm and 228 mm. All series-A products have a high degree of protection (IP66) and, with IK09, are particularly impact-resistant and therefore vandal-proof. Like the Q series, the A series is also suitable for industrial, processing and marine applications.

    The loudest multi-tone sounder of series A is the ASX, which achieves a sound pressure of 127 dB. Up to 63 keys can be selected. But also the smaller devices boast high performance.

    The multi-tone sounders of the A series can be combined with a luminaire of the M22 series. This combination is suitable if you want a dominant multi-tone sounder with an optical supplement in the form of a light indicator. All combinations are available in four sizes. Multi-tone sounders from series A in combination with series Q luminaires can be found in our product series A+Q.

      Series T+U - the Allrounder
        Our T+U series is a comprehensive and modular signal device series in two sizes – Ø 60 mm and Ø 75 mm – for universal use. Their products are suitable for use in extreme temperature fluctuations. T+U series luminaires are available in six different dome colours and as LED or incandescent lamps. The LED models are available with continuous, flashing and multi-flash functions. The lighting functions can be selected via terminal assignment.

        Selected luminaires from the T+U series can be upgraded to an optical-acoustic signal device with the piezo buzzer TDE. The T series buzzer can be used as a continuous or pulse tone. Light and sound can be controlled separately with a combination product. The combination of both modules has protection class IP66.

          Series M22 - the Installable
            The most comprehensive M22 built-in signal device series is available in three sizes: Ø 30 mm, Ø 45 mm und Ø 65 mm. The high luminosity and signal effect is seen frontally and laterally due to the calotte. The luminaire is particularly durable and vibration-resistant, with a high degree of protection of IP65 and IP67 for prewired models.

            The M22 series buzzer, the loudest installation buzzer available on the market, is available as an add-on for the installation series. The high sound pressure level (max. 100 dB) is mostly infinitely variable. Luminaire models with LED technology can be upgraded to an optical-acoustic combination with the piezo buzzer. Sound and light can be synchronised or separately controlled.

              Series K+H - the Little & the Great Loud
                The K+H series combines beautifully shaped and robust electromechanical signal horns with the unmistakable, classic horn tone. In our range you will find signal horns and small horns with or without a funnel. A signal lamp is available as an add-on for K+H series horns. The optical-acoustic combination of the K+H series enables the use of a small horn with a flashing light in xenon and LED technology or with a conventional bulb. Available with or without a funnel.
