Fail Safe Destination Reporting Wiring

The difference between standard fail safe operation and destination reporting operation is that the floor relay only changes state when a user selects a floor, preventing more than one floor from being selected.

Fail safe destination reporting requires an additional wire from the contacts of the relay to the input terminal on the PRT-ISO16-DIN. A button voltage common wire is also required from the elevator control system.

Note: It is important that the active input to the PRT-ISO16-DIN is linked from the side of the relay that is not switched.
