The P4 Controller is designed to be programmed both stand alone and from a PC. The built-in keyboard gives access to all the menu functions. This means the controller can be installed and operational even before the network and PC are available. In addition, there is no dependence on any central hardware for operation. If the network cable is cut or the controlling PC is not available, all the controllers will continue to work. A P4 system will efficiently and cost effectively service the smallest single door application. The system architecture allows it to be expanded without any major new equipment. This means that P4 will not only suit large and small systems but also allow small system to grow with your needs.
