Information About SK-FSL
The SK-FSL is a single-mode fiber loop module designed for use with the Honeywell Silent Knight SK-NIC Network Interface Card to create reliable fiber-optic communication links between control panels. It supports 9/125 μm single-mode fiber with LC-style connectors and can tolerate up to 30 dB of signal attenuation, ensuring excellent transmission quality even across long distances. The module works as either a transmitter or receiver in an ARCNET communication circuit, allowing full-duplex data flow across fire alarm networks. Designed to integrate with Silent Knight 6000 Series panels, including the 6820, 6820EVS, 6808, and 6700 models, the SK-FSL enables multi-site communication and simplified system management.
Key Features:
- Single-Mode Fiber Compatibility: Designed for 9/125 μm single-mode fiber cables, offering reliable, interference-free data transmission over extended distances.
- High Signal Attenuation Tolerance: Maintains consistent performance with up to 30 dB attenuation, making it suitable for complex installations and long cable runs.
- LC-Style Connectors: Utilizes compact and secure LC connectors for easy fiber termination and strong signal integrity.
- Plug-In Installation Design: Simple, tool-free installation directly into the SK-NIC slot allows quick upgrades or replacements without rewiring.
- Dual Fiber Loop Operation: Supports up to two fiber loop cards per SK-NIC, enabling network redundancy and flexible configuration between single- and multimode modules.
- ARCNET Network Communication: Enables high-speed ARCNET data transfer for fast and reliable synchronization between fire alarm panels.
- UL 864, 9th Edition Certified: Complies with ANSI/UL standards for safety and performance in fire alarm applications.
- Environmental Resilience: Engineered to function in temperatures from 32°F to 120°F and up to 93% relative humidity, ensuring stable performance in demanding environments.
The SK-FSL delivers the reliability and precision required for long-range, high-performance fiber-optic communication in networked fire alarm systems.
