Notifier NFS-320S Intelligent Addressable Fire Alarm Control Panel

The NFS-320S is a mid-sized intelligent fire alarm control panel. It offers all the intelligent features, capacity, and reliability of the NFS-320, but its main control chassis utilizes a more space-saving, integrated design.

"S": Commonly understood as "Single Cabinet" or "Slimline," it emphasizes its design, which integrates key components into a compact chassis.

Core Role: It is an ideal choice for mid-sized projects that require the powerful features of the NFS-320 but have limited installation space (such as small distribution cabinets).

Key Features and Technical Advantages

1. Same Core Performance as the NFS-320

First, it is important to understand that the NFS-320S inherits all the advantages of the standard NFS-320:

Total Device Points: Supports up to 1,590 intelligent device points.

SLC Loops: Expandable to up to 5 signal loops (using XPC-5 loop cards).

Network Capabilities: Can be integrated into Noti-Fire-Net networks.

Advanced Protocols: Supports both FlashScan® and CLIP protocols, providing fast loop scanning and backward compatibility.

VERIFY® Intelligent Sensing: Effectively reduces false alarms.

Loop Cabling: Supports high-reliability Class A (Style 7) cabling.

2. Compact All-in-One Chassis Design (Key Difference)

This is the core difference between the NFS-320S and the standard NFS-320:

The standard NFS-320 typically consists of a basic main control chassis (CHS-4L/C) and a separate power supply (such as the XPS-10), which may require more cabinet space for combined installation.

The NFS-320S integrates the main control board, power supply, and battery charger into a single, compact chassis. This makes installation easier and takes up less space overall.

3. Built-in Power Supply

The NFS-320S chassis integrates a power supply that directly powers the panel and connected devices, eliminating the need for external power modules and simplifying wiring and bill of materials.

Hardware Components and Appearance

A typical NFS-320S system includes:

Master Control Chassis: An integrated chassis containing the CPU, power supply, and battery connectors.

SLC Loopback Card: A card that requires additional insertion, such as the XPC-5 card, which provides five SLC loopbacks.

Battery: Connects to an external backup battery.

Display Panel: An LCD-80 or LCD-160 text display is typically standard or optional.

IV. Typical Application Scenarios

The NFS-320S is suitable for all medium-sized projects where the standard NFS-320 is suitable, especially in the following situations:

Space-constrained distribution cabinets/control cabinets

Small and medium-sized office buildings and retail stores

School and hospital floors

Hotels

Projects requiring upgrades to existing systems with limited cabinet space
