Abstract

A number of detectors are scanned in groups. A relay for each group and a relay for each column is used in a circuit where the detectors operate as an open or closed circuit element. A number of detectors are arranged in groups (111, 112 and each detector operates with contact elements (15) which cause terminals (14, 15) to open or close a circuit between conductors (17, 18). Switches (19) included in the circuits are operated by the armature (25) of a relay (26) or electromagnet. The conductors (18) are connected to a 16 fit processor via electromagnet (31) switch circuits. As each relay (26) is excited the processor records the open or closed circuits.
