Fager System 4020 Alarm Fiber Optic Communication

The Fager System 4020 Alarm integrates fiber optic communication to transmit multiple alarm signals over long distances with high reliability and bi-directional capability.Overview

The Fager 4020 Alarm System (also known as Simplex SafeLINC 4020) is a fire alarm control panel designed to manage fire, supervisory, and trouble signals while providing networked communication capabilities. It supports fiber optic communication to connect multiple panels or remote devices, simplifying wiring and extending transmission distances .

Fiber Optic Communication

The system uses Multiple Signal Fiber Optic Modems to convert standard alarm signals into fiber optic signals. These modems allow bi-directional communication by transmitting and receiving over two different light wavelengths. To establish a complete fiber optic link, complementary modem pairs (Left-Port and Right-Port) are required .

Key Features:
  • Single or Multi-Mode Fiber: Single-mode fiber is preferred for longer distances, while multi-mode fiber is measured at 850 nm and 1300 nm for attenuation .
  • Bi-Directional Couplers: Using a 4190-9010 coupler at each end allows network communication over a single fiber cable, though with some reduction in distance .
  • Media Modules: Compatible fiber optic media modules include 4010-9819, 4100-6057, and 4190-6037, which require two fibers (one for transmit, one for receive) unless using bi-directional couplers .
  • ST Connectors: The system uses ST-type connectors, and ST-to-ST couplers may be required for connections .
System Components
  • Control Panel: Displays fire, supervisory, and trouble signals, logs events, and manages TrueAlarm sensor data .
  • SafeLINC Modules: Wireless message devices can receive signals directly or via forwarded e-mail messages, integrating with IT systems for alarm notifications .
  • Fiber Optic Media Cards: Installed in the panel to enable fiber optic communication, ensuring reliable signal transmission over long distances .
Installation and Operation Considerations
  • Proper Installation: Correct installation is critical for system reliability. Panels, detectors, and transmitters must be installed according to manufacturer guidelines .
  • Power Supply: The system requires stable AC power or properly maintained batteries. Power interruptions can affect operation .
  • Maintenance: Regular testing and battery replacement are necessary to ensure continuous operation .
  • Environmental Factors: High humidity, temperature extremes, or physical obstructions can affect wireless or fiber optic signal performance .
Applications

The Fager 4020 system is suitable for large facilities or multi-building campuses where long-distance, reliable fire alarm communication is required. Fiber optic communication reduces electromagnetic interference and allows centralized monitoring of multiple panels. In summary, the Fager System 4020 Alarm with fiber optic communication provides a robust, networked fire alarm solution with bi-directional fiber optic links, modular media cards, and integration with wireless and IT-based notification systems, ensuring reliable alarm transmission across extended distances .
