Bosch PRA-CSE Expansion of call station

BOSCH PRAESENSA PRA-CSE Call station extension is used in combination with PRAESENSA call stations to make selections for business and alarm calls. One device adds twelve configurable buttons with a light ring. Each button has two additional indicators 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.
