Immediate and targeted information of care personnel is crucial for an early evacuation. Coupling the fire detection system with the nurse call system provides valuable time advantages: Both systems are connected in such a way that a fire alert is also represented in plain speech on the nurse call system displays for example in the duty rooms or via the DECT telephones. The personnel can now immediately initialize first firefighting measures or an orderly evacuation, even before the fire department arrives. This coupling was usually achieved via a serial Essernet interface (SEI). Ackermann Clino and Esser now offer a cost-effective alternative in which the connection between the fire alarm system and nurse call system is achieved directly via the fire department indicating panel (Fat3000). Collective announcements can be configured within the nurse call system. Using a coupling terminal configured as a gateway (room terminal & VA/PA interface) voice alarm announcements can be activated through the nurse call system.
