  • Control via software, network or API
  • Visual and/or audio indication
  • Easy integration into IT, OT and automation environments
  • Suitable for both industrial and administrative systems

Areas of use

  • Machine and process status in smart factories
  • IT operations, servers and network monitoring
  • Production monitoring and andon systems
  • Alarm and event indication in control rooms
  • Workstations, test environments and support functions

FAQ

What is a wireless signalling tower?

  • A wireless signalling tower is a visual and/or audible warning device that can monitor status or alarms in industrial or commercial environments without the need for fixed cables. It communicates via wireless technologies such as Wi-Fi, Zigbee, Bluetooth or mobile networks.

 

What are the advantages of wireless signalling towers compared to wired ones?

  • Easy installation without wiring.
  • Flexible placement and easy to move when needed.
  • Possibility to integrate with existing networks and remote monitoring.
  • Less risk of damage to cables in heavy industrial environments.

 

What types of signals can wireless signalling towers send?

  • Light signals in different colours and levels.
  • Audio alarm with adjustable volume and tone.
  • Voice messages with Text-to-Speech (TTS).
  • Digital messages to computers, PLCs or cloud services.

 

How long is the range of the wireless signals?

  • The range depends on the technology and the environment. Wi-Fi based signals typically work within the same network, while Zigbee or Bluetooth have shorter ranges (10-100 m). Some models can amplify the signal via mesh networks.

 

Can wireless signalling towers be integrated with control systems?

  • Yes, most modern wireless signalling towers can be connected to PLCs, SCADA systems, IoT platforms or cloud services for real-time monitoring and alarm management.

 

Are wireless signalling towers as reliable as wired ones?

  • Yes, when they are properly installed. Many industrial wireless signalling towers are designed with redundant protocols and secure connectivity to ensure high reliability even in complex environments.

 

Do I need special programmes or apps to control them?

  • Software or apps are often included, but some models can be controlled via standardised protocols such as SNMP, HTTP/HTTPS or via cloud services without additional installation.

 

Can wireless signalling towers be used in industrial environments with high interference?

  • Yes, many models are designed for EMI/EMC resistant environments, and some have extra robust enclosures for moisture, dust and vibration.
