The two-part signal system consists of numerous technical appliances which transmit acoustic and optical signals. In addition to the shaft telephone and speaker, alarm bell and alarm trigger, light signals are also transmitted from the lamps, in order to organise communications between slingers and hoist operators in the pit in the best way possible. The head of Ensdorf pit added another set of separate operating instructions relating to materials handling as an attachment.
