The right signal tower for your applications

Depending on the requirements and the application, different signal towers are used. That's why our portfolio includes signal towers in various designs and technical specifcations - from compact warning lights for simple requirements and high volumes to more complex modular signal towers for special and technically demanding applications.

All our signal towers are characterized by highest material quality and performance, long-term reliability, high protection classes and most innovative technical solutions.

Our signal lights ensure optimum safety

Signal lamps or warning lamps indicate the operating status of machines and systems and thus make an important contribution to the safety of employees and their production processes. Our signal lights convince with a high-tech calotte design, which enables a signal effect in all directions.

In our portfolio you will find LED strobe lights, flashing lights, LED continuous lights as well as multifunctional lights. Depending on the model, our signal lights are designed as recessed or surface mounted lights.

Audible alarms

Our signal horns, multi-tone sirens, piezo buzzers and alarm clocks are used on special vehicles and cranes, among other things. Since the visibility of an optical device is limited or not given at all there, one relies on acoustic signals. The volume of our acoustic signaling devices reaches up to 127 dB.

With an IP protection of IP66 and an impact resistance of IK09, our acoustic signaling devices are also suitable for use in extreme conditions.

Signaling that can be seen and heard: Our visual-audible signaling devices

Some machines and production processes require acoustic signals in addition to visual signaling to warn employees of hazards or process changes. Optical-acoustic signaling devices are available for these requirements. They combine a luminous signal (e.g. continuous light) with an acoustic signal (e.g. multi-tone siren).

The visual-audible signaling devices in our portfolio achieve a volume of up to 127 dB and an output of up to 400 candela. They are used in mechanical engineering, automotive plants and production automation, among other applications.
