The SPCE120.100 is a universal display expander with 16 tri-color LEDs, 4 keys, integrated card reader and buzzer. In linked mode with a keypad the LEDs indicate the status of 4 areas in one glance and the areas can be directly set or unset with the assigned function keys. In flexible mode the freely programmable user interface indicates the configured status information with LEDs (e.g. open zones, area setting states) and enables activation of application specific processes by pressing the assigned function keys (e.g. setting of an area, open or close a gate). With the integrated card reader the indication or operation can be enabled for authorised users only by presenting a valid proximity card. The expander also provides one freely programmable zone which can be configured for different zone monitoring requirements.
