Abstract
Abstract A control and display system for an electronic security system which comprises a thin flat multilayer panel which provides a touchpad for entry of data and display areas for the selective display of messages and legends. The system is contained within a small wall mounted housing which includes a microprocessor controller cooperative with the panel. The system operates as a data terminal in communication with a master control unit and is operative in response to touchpad actuation for providing data to the remote unit, and it is operative in response to data received from the remote unit for actuating displays and associated annuciators. The system is programmable via the front panel, and input and display modes can be tailored to suit particular operational requirements.
