Systevo connection unit with signal light for providing the required call system and control functions in occupant/patient/service room according to DIN VDE 0834. Separate cover in color white / silver required. Optional use of the nameplate. Serves as a control unit for additional functions in the respective room and as a gateway to the higher central unit (data bus).Monitoring/synchronization of all data traffic as well as audio connections (calls, announcements) to other rooms within the organizational unit, coordination of communication with the central units and other participants via data bus. Configuration data management via the central unit, redundant local flash storage and use of profiles (functions, I/O, device services).Connection of the multifunctional room units via the data bus (DBUS) as well as use of call inputs (I/O) for connection to the room controller and integration into the data bus, ZBUS.Use of user-friendly installation technology with colour-coded terminal blocks for the individual device and control functions, for efficient cabling and optimization of the commissioning process. Upgradable to future system firmware thanks to pioneering flash and memory technologies: Possibility of automated software update during operation.Multi-level security concept enables local call signaling in the event of a lack of communication with the central unit of the system. Meeting the cyber security requirements of modern data bus infrastructures. Licensed system functions are provided by corresponding software licenses.Special material properties:High quality plastic compound with antimicrobial surface to reduce microorganisms and inhibit the growth of germs.Good mechanical properties with high resistance for daily use (operating, cleaning, disinfection, shock, etc.).Suitable for use in nursing facilities with high demands on hygiene, stability and durability.Plastic (PC+ABS-FR), mattUV-resistant, impact resistanceHeat resistance, strengthDurability, halogen-freeFlame protection (fire protection class V0)Accessories:Cover in color silver and whiteNameplateSystem infrastructure:Processor/OS: Embedded μC System CyberSecurity: Firewall, Secured Boot Loader FunctionConfiguration: via data serviceInputs/outputs:Power supply 24V DCDBUS: 2x RS487 (each 200m) for 4 users eachZBUS: 1x RS487 (500m)Call input/output: 4x I/OConnection terminals: color-coded for up to 3x 0.6mm (2x 0.8mm) rigidGalvanic isolation of control functions according to EN 60601.1.1 by external protection measures
