BNW-S

The BNW-S continuously monitors the power supply of emergency lighting installations and contributes to the reliable operation of safety lighting systems. By permanently supervising the electrical network, critical conditions can be detected at an early stage and transmitted to the central monitoring system.

The device is designed for three-phase networks and detects both phase failures and undervoltage conditions. This enables reliable identification of supply-related faults and supports the initiation of appropriate responses within the emergency lighting infrastructure.

Integration is achieved through a bus connection, allowing the BNW-S to become part of a centralized emergency lighting monitoring system. Using integrated address selectors, each monitoring unit receives a unique address between 1 and 99. This structured addressing concept supports clear device identification and enables multiple monitoring points to operate within the same system architecture.

DIN rail mounting supports organized installation inside electrical distribution cabinets and aligns with established installation practices. As a result, the device can be integrated easily into existing electrical infrastructures while maintaining a structured and scalable emergency lighting monitoring concept.

• three-phase monitoring enables reliable supervision of power supply conditions
• phase failure detection enables rapid response to critical network events
• undervoltage monitoring enables early identification of electrical supply issues
• bus communication enables integration into centralized emergency lighting systems
• unique addressing from 1 to 99 enables clear device identification within the system
• DIN rail mounting enables straightforward integration into electrical distribution cabinets
• continuous monitoring supports improved operational reliability
• structured system architecture reduces planning and installation complexity

The BNW-S supports structured monitoring of power supply conditions within emergency lighting systems and contributes to the planning of safety-critical installations. Through integration into bus-based monitoring infrastructures, key network parameters can be supervised centrally, creating a clear overview of the electrical supply status throughout the installation.

The addressable architecture enables individual monitoring points to be clearly defined and systematically integrated into larger projects. This supports scalable system concepts and simplifies the planning of complex emergency lighting infrastructures. Since the device is installed within the electrical distribution cabinet, it has no impact on the architectural appearance of the building while providing reliable technical supervision in the background.

The BNW-S is designed for DIN rail installation and follows established practices used within electrical distribution cabinets. This enables straightforward integration into existing switchboards and supports a clean and organized arrangement of system components.

Bus communication allows simple connection to the emergency lighting monitoring infrastructure, while integrated address selectors provide unique identification for every device. Each BNW-S can be assigned an address from 1 to 99, reducing the risk of confusion when multiple monitoring units are installed within the same system. The clear connection concept supports fast installation, minimizes potential wiring errors and simplifies commissioning and future maintenance activities. For installers, this results in efficient implementation, reduced coordination effort and reliable system integration.
