In a hospital environment, communications is a critical component of efficient care delivery, most notably when a patient requires immediate assistance. The Bosch PSP‑D00039 Master and PSP‑D00040 Slave Redundant network Controller Switch (RCS) units are special versions of the PRS‑NSP network splitter, mechanically and electronically identical to the network splitter, but with different firmware to establish an automatic switch‑over from a main to a spare network controller. The PSP‑D00039 Master and PSP‑D00040 Slave RCS units and two normal network controllers create a redundant controller solution for increased system reliability in situations where the network controllers are more exposed to risks (ships, heavy industry). PRAESIDEO by Bosch is a complete, full-featured digital public address and emergency sound system. Bosch Praesideo has the flexibility and scalability to keep all these adjacent systems working throughout the transition.
