Zusammenfassung:An electronic test node (1) for a safety chain (22) in a passenger conveyor system comprises an electrical connection (2) for an associated safety switch (4). A processor (6) is configured to monitor a signal carried by the electrical connection (2) so as to detect whether the associated safety switch (4) is open or closed. The electronic test node (1) further comprises a test switch (8) connected in series with the electrical connection (2), wherein the processor (6) is configured to run a test by selectively opening the test switch (8) and monitoring for a change in the signal carried by the electrical connection (2).
