Signaling Device

Optical-Acoustic Alarm

The optical-acoustic alarm (O2A) combines a siren with optical signaling by using highly efficient LEDs. The compact device offers many special features such as individual configuration, chaining, logging and much more.

O2A is a product that has been designed and optimized for future requirements. Thanks to its extensive functions, O2A can be used for various applications in industry, but also in the private sector.

Solution Through Innovation

Several signal transmitters can be operated in a network in parallel. If the control unit does not provide enough energy, an external energy source can be connected, which supplies all subsequent signalers with electricity. All signaling devices in a chain can be triggered simultaneously by the control unit. Each device allows the connection of an optional switch, which enables extended functions, such as the individual control of a device.

Chaining with individual control of the signaling devices
