Abstract: A method for self-testing a monitoring device monitoring an integrity status of an elevator suspension member arrangement includes the monitoring device having a voltage generation arrangement for generating electric voltages and applying the electric voltages to cords in suspension members of the suspension member arrangement. The monitoring device has a voltage analyzer arrangement for detecting a deterioration in the integrity status based on modifications in the applied electric voltages upon transmission through the cords.

Abstract: A wire bridge monitoring system includes a wire bridge (18) and a monitoring device (22, 24). The wire bridge (18) is used by a technician (20) during servicing an electrical or electro-mechanical installation (1) to bridge a component of the electrical or electro-mechanical installation (1). The wire bridge (18) has an electronic identification device (26) configured to transmit a radio signal (21) comprising an identification number of the wire bridge (18). The monitoring device (22, 24) has a transceiver (28, 37), a memory (23, 41) and a processor (31, 39). The transceiver (28, 37) receives the radio signal (21) transmitted by the electronic identification device (26) when within a predetermined radio range, and the memory (23, 41) records use of the wire bridge (18). The processor (31, 39) monitors if the wire bridge (18) is within the predetermined radio range, and generates an alarm if the wire bridge (18) is not within the predetermined radio range and the wire bridge (18) is recorded as being in use.
