The System Complies With The Product Standard En 54.//The Fire Alarm Center Is Connected To The Local Fire Department. The Control Center Is Installed In The Basement (Room -1.Tf.025A) In A Designated Room. The System Is Constructed Using Fail-Safe Ring Technology (Separate Rings For Administration And Exhibition Rooms). To Avoid False Alarms, Automatic Multi-Criteria Detectors With Base Sirens Are Used. Manual Call Points Are Installed At The Entrances To The Stairwell For The User Areas (According To Din 14675).// Explanation Of The Cabling: The Cabling In The Ring Mains Network Is Carried Out Across Fire Sections Using Red Fire Alarm Cables Using 4-Wire Technology. Cost-Saving And Expandable Cabling Of The Detectors And Control Devices Must Be Ensured. Each Detector In The Ring Network Receives Its Own Bus Subscriber Address. This Makes Individual Detector Identification Possible. To Ensure Greater Reliability, The Line Network Of The Fire Alarm System And The Equipment Must Be Designed In Such A Way That Only Some Of The Detectors Or Network Elements In This Ring Fail Due To A Short Circuit Or An Interruption In The Ring Line. All Other Ring Main Components Remain Functional. // The Following Peripheral Connections Are Planned: Transmission Device (Üe) With Main Detector (Hm), Fire Brigade Control Panel (Fbf), Fire Brigade Display Panel (Fat), Fire Brigade Key Depot (Fsd) Class 3, Activation Element
