Video control unit REG Features: Control unit for supplying the audio and video components of the Gira door communication bus. Supply of the reverse polarity and short-circuit-proof 2-wire bus when using video components such as color camera, TFT color display. Up to 2 door stations with color camera and 28 home stations with TFT color display can be supplied via the video control unit. A total of up to 15 color cameras can be controlled by the video control unit (5 video door stations and 10 TKS camera gateways), of which two door stations with color camera can be supplied with power from the video control unit. The other color cameras must each be operated with their own power supply for door communication. Self-resetting electronic short-circuit and overload detection of the operating voltages and the bus connection. Buttons for system and door opener programming. LED status displays for operation, overload, system programming and door opener programming. AC 12 V output for supplying power to a standard door opener. Relay output for switching a door opener with its own power supply. Door opener switching time continuously adjustable from 1 to 10 s. Notes: The video control unit is designed for installation in the sub-distribution, not for commercially available surface-mounted distributors. If the topology of the video cabling is designed as a spur line, the video distributor is also required. In combination with the TKS-TK gateway, the power supply for door communication is required. The video control unit can be used to set up door communication systems with up to 70 audio participants (e.g. 1 x built-in loudspeaker, 5 x extension module for built-in loudspeaker, 68 x AP home station).
