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.
