Abstract
The system is used for safety alarm signalling when the signals are transmited from remote stations to a central control room. The cct. contains a coding unit with several inputs which react to changes in the state of one of its inputs. This generates a coded output signal indicating the number of the input registering a change of state. The output signals are scanned and are digitally reproduced on a display panel in the control room, identifying the remote station originating the alarm.
