Function Display and Audible Checkback

Function Display And Audible Checkback

The operating state of the central locking system is fed back via the output 'Door locked' and by corresponding activation of the interior light(signals 1 to 3). The operating state of the alarm system is also indicated during the inactive period by the alarm readiness display (display types 1 to 6). It is indicated exclusively by the alarm readiness display after the inactive period has expired. Displayed system faults are always current faults. Previous system faults entered in the status memory have no effect on the function display.
