Other computer peripherals, video peripherals, audio equipment, etc. are connected to the computer's input, so that the line connection is very clear, easy to install, use, and maintain.
computer network
The system can be remotely controlled via a computer.
Overhead Sectional Door
Overhead sectional door most widely used for loading areas on all types of industrial premises and Designed with a curved overhead track, these vertically-opening sectional doors can be installed in areas with reduced head room. They provide heat and sound insulation with its composite panel construction.
The counterbalance and cable system provides quiet and straight forward operation for manual doors. Electric operation is available for larger applications that can incorporate many alternative operator options to suit all client requirements.
The standard outer panels are manufactured from 0.5mm thick, high quality zinc coating to BS EN 10147
For the best weather protection the sectional door panel has an interlocking hinged joint integrating a high quality seal the full length of the panel.
A counterbalance system is incorporated into the sectional overhead door to ensure efficient and effortless operation.
The counterbalance comprises of springs mounted on a steel shaft that are high tensile helical wound steel. It has been heat treated for enhanced performance for around 50,000 cycles.
Reducing shaft friction is achieved with the aid of brackets and guide rollers incorporating highest quality sealed bearings.
