The NFS2-3030 is a programmable intelligent fire alarm control unit from Honeywell's Notifier brand.
System Positioning: It belongs to Notifier's high-end ONYX® series. Known for its superior performance, reliability, and flexibility, the ONYX series is the preferred choice for many airports, hospitals, data centers, high-rise buildings, and industrial facilities.
Core Role: Serving as a master control panel or node panel in a large network, it monitors fire alarm devices (such as detectors and manual call points) within the entire protected area and activates appropriate firefighting equipment (such as audible and visual alarms, smoke exhaust valves, and sprinkler systems) upon confirmation of a fire.
Key Features and Technical Advantages
1. Large Capacity and Scalability
This is one of the core advantages of the NFS2-3030, making it suitable for large-scale projects.
Total Number of Monitoring/Control Points: Supports up to 3,180 intelligent device points. A "point" here can be a smoke detector, a control module, etc.
Signaling Loop Card (SLC): Accommodates up to 10 SLC loops. Each loop can connect up to 318 intelligent devices (using Notifier's AFP-300/400 protocol).
Networking Capabilities: Supports Noti-Fire-Net networking, allowing up to 32 ONYX series panels (such as the NFS-320, NFS-3030, and NFS2-640) to form a comprehensive fire alarm system covering an entire building.
2. High Reliability and Redundancy
Dual CPU Design: Both the main control board and the SLC loop card utilize dual microprocessors, one for communication and one for monitoring, significantly improving system reliability.
Ring Loop Wiring: The SLC loop supports both "T-Tapped" (branching) and "Style 4/7" (ring) wiring. The advantage of ring wiring is that if a circuit break occurs anywhere in the loop, the system can still communicate through the other end of the loop, significantly improving system survivability.
Redundant Power Supply: Supports automatic switching between the primary power supply (AC 220V) and the backup power supply (high-capacity batteries), and an optional redundant power supply module is available.
3. Advanced Communication and Protocols
FlashScan® and CLIP™ Modes:
FlashScan®: Notifier's advanced protocol doubles the communication speed between devices on the SLC loop, significantly reducing system status scan time.
CLIP™: Traditional mode. The NFS2-3030 is fully compatible with both modes, allowing devices of both modes to be mixed on the same loop, protecting user investment.
VERIFY® Intelligent Algorithm: For smoke detectors, it analyzes the changing trends of smoke concentration to effectively distinguish between real fire smoke and transient interference (such as dust and water vapor), significantly reducing false alarm rates.
4. Flexible Programming and Diagnostics
Programming Software: Powerful VeriFire® Tools software offers graphical programming with clear logic and powerful functionality. Users can customize complex control logic and linkage programs.
Diagnostic Information: The panel provides detailed diagnostic information, including the address, status, and sensitivity of each device, facilitating rapid troubleshooting.
Hardware Components and Appearance
A typical NFS2-3030 chassis includes:
Main Control Chassis: Mounted in a standard 19-inch rack.
Main Control Board (CPU): The core of the system.
SLC Loop Card: Plug-in as needed; each card provides two SLC loops.
Power Supply: Internal or external power supply module.
Display and Operation Panel: Typically equipped with an LCD-80 or LCD-160 display, it provides full Chinese text and operation buttons, allowing on-site personnel to easily view fire alarm and fault information and perform operations such as confirmation and reset.
