The RZB LUXIFAIR KV 2000 is a central supply and monitoring system for emergency lighting. In case of a power failure, the system can supply luminaires up to an output of 2000 W for 1 hour or 800 W for 3 hours and even 350 W for 8 hours. The system is available with up to 20 output circuits, up to 20 luminaires per circuit. A location can be assigned for each luminaire, which is displayed in clear text in case of failure, to ensure clear localisation of the connected luminaires. Powerline communication is used for communication between the system and the luminaires. Bus lines to the luminaires are not necessary. The system can also exchange KNX, BACnet or Modbus data via the optionally available gateways. Monitoring via TCP/IP with e-mail sending in case of failure is also optionally available. Up to 32 systems from the RZB LUXIFAIR series can be monitored together from a central location using the optional PRovisu software. Switching operations can be triggered via the series-standard digital inputs and messages can be forwarded to a superordinate GLT or a message and switchboard via the isolated changeover relay.
