Introduction
The VK8K Series is a new range of videokits that use the 8000 Series external door station and the Art. 6256 videophone which is
specific for this range of videokit and VK4K videokit. The camera/audio unit is the size of a one point five 8000 Series module and is
available in either flush (VK8K) or surface (VK8K-S) mounting versions.
As a result of using microprocessor technology in the door panel and videophone, a number of additional features have been add-
ed to enhance the operation of the videokits and give greater feedback to the visitor and user.
• Disability friendly, acoustic signals from the door panel to inform the visitor of call status (call made, ringing, speak, door open).
• Two methods of operating the electric lock:- 1) Dry contact relay, 2) capacitor discharge circuit.
• Connections for a push to exit button.
• Programmable door open and conversation time.
