Zusammenfassung:A remote elevator monitoring system includes a master (18) associated with a building and a local (14) connected to the master. The local includes an electronic processor (28) which executes instructions for determining whether the master has transmitted a signal packet to the local within a time period selectable at will by an operator at the local. The time period is, for example, a period selected within a range of 0-255 days. Optionally, for example, the master is programmed to transmit a signal packet to the local at a selected time on the last day of the selected time period.
