Needing an alarm system that is both visible and audible doesn’t mean you have to purchase two separate products.

Auer Signal offers a complete range of optical and acoustic signaling devices, designed to generate combined optical and acoustic signals — all in one compact and effective solution.

• Ideal for both indoor and outdoor use, thanks to their powerful light and sound emission.
• Perfect for critical areas where immediate attention is required.
• Designed to ensure maximum visibility and audibility at long distances.

Our signalers reach sound pressure levels of up to 120 dB and are equipped with intensely bright lights, ideal for creating a strong and clear warning effect.

Available with protection ratings up to IP66, these devices are resistant to dust, water jets, and challenging environmental conditions.

Choosing a combined optical-acoustic alarm means saving time, space, and costs — without ever compromising on safety.
