The Notifier NFS-320 (Standard) and NFS-320E (International/Export version) are intelligent fire alarm control panels designed for small-to-medium-scale facilities. Part of the ONYX® Series, these systems provide a powerful, scalable solution for life safety, combining advanced detection algorithms with user-friendly operation. The NFS-320 is engineered for high-speed communication and modularity, making it a cornerstone for integrated fire protection and emergency notification systems.

Key Features
- Intelligent Sensing: Utilizes FlashScan® technology for rapid polling of devices (less than 2 seconds).
- Network Capability: Compatible with Noti-Fire-Net™ for larger, multi-panel integrated systems.
- Flexibility: Supports a wide range of detectors, manual pull stations, and notification appliances.
- Maintenance Tools: Integrated walk-test features and extensive diagnostic logs for service technicians.
- Programming: Configurable via VeriFire® Tools, allowing for complex cause-and-effect programming.
Application Fields
- Commercial Buildings: Offices, retail stores, and small warehouses.
- Educational Facilities: Schools and university buildings requiring integrated notification.
- Healthcare: Clinics and small healthcare facilities needing strict regulatory compliance.
- Industrial Sites: Facilities requiring addressable detection for localized emergency shutdown and alert.
Usage Instructions
- Installation: Mount the cabinet in a secure, climate-controlled location. Ensure adequate clearance for door opening and service access.
- Wiring: Connect the SLC loop using twisted-shielded cable to minimize noise interference. Ensure proper end-of-line (EOL) resistors are installed for NACs if required.
- Configuration: Use VeriFire® Tools to upload site-specific programming. All system configuration must comply with NFPA 72 and local building codes.
- Commissioning: Perform a full point-by-point functional test to verify that every detector, module, and notification appliance responds as expected during an alarm condition.
- Maintenance: Conduct annual system inspections, including sensitivity testing of smoke detectors and battery load testing, as mandated by local AHJ (Authority Having Jurisdiction) requirements.

Frequently Asked Questions (Q&A)
- Q: What is the main difference between the NFS-320 and NFS-320E?
- A: The NFS-320 is designed for North American power standards (120V), while the NFS-320E is the export/international version designed to handle 240V power environments.
- Q: Can I expand the device capacity?
- A: The NFS-320 supports one SLC loop. For larger facilities requiring more devices, Notifier offers the NFS2-640 or NFS2-3030 systems which support multiple SLC loops.
- Q: Is the system compatible with non-Notifier devices?
- A: The system is designed specifically for the Notifier family of intelligent devices. Mixing manufacturers can lead to system instability and loss of UL listing.
