for user feedback, related to the configured functionality of that button.
Up to four PRA-CSE can be connected to one call station. Using extension keypads for zone selection allows all zones to be accessible and visible at the same time. It shows a complete status overview of selected and occupied zones or zones with faults.
The extension keypad is delivered with a metal coupling plate and patch cable to link it to a call station or other extension keypad. The front cover can be easily removed to insert labels with up to three lines of text per button and a header section on top.
