Bell 4 Way Isolated Video Controller

Bell BSC4 Video Controller is a high-performance four-way isolated distribution unit designed to manage and protect the signals for up to four videophones within a bellissimo digital entry system.

The BSC4 is a fundamental component of the 2-72 way bellissimo platform, acting as the intelligent bridge between the door controller and the internal apartments. Its primary function is line isolation; it independently manages four separate output branches, ensuring that a fault, short circuit, or physical damage to a videophone in one flat does not compromise the operation of the rest of the building. The unit is engineered to work exclusively with standard CAT5/CAT5e cabling, utilizing the twisted-pair architecture to deliver balanced video, high-fidelity audio, and digital data without the need for co-axial cables.

Features

• Four-Way Branch Isolation: Provides four independent outputs with integrated protection. If an individual station is damaged or incorrectly wired, the Isolation circuitry prevents the fault from propagating to other controllers or entrances.
• Integrated Video Amplification: Features built-in signal boosting to maintain high-resolution color images across cable runs of up to 150 meters from the controller to the videophone.
• 28V Internal Power Generation: While the system is powered by a 12V DC PS4 supply, the BSC4 internally generates the 28V required to drive the TFT displays, ensuring energy efficiency and simplified wiring.
• Versatile Mounting Options: The controller is housed in a robust plastic enclosure suitable for surface mounting or installation within a secure electrical cupboard or riser.
• Diagnostic Indicators: Features onboard LED status indicators to assist engineers with rapid troubleshooting and verification of power and data flow during commissioning.
• Daisy-Chain Scalability: Multiple BSC4 units can be linked together to support systems ranging from 2 to 72 stations, with a dedicated output for To more BSC4s to simplify complex riser wiring.
