Enter the specific three-digit address of the device (001 to 159).
Choose the polling protocol. FlashScan is significantly faster and should be used for all modern installations.
Automatically detects all intelligent detectors and modules currently wired to the Signaling Line Circuit (SLC) loop.
Assigned type codes like CONTROL or RELAY to activate notification appliances (horns/strobes) or trip relays. 4. Software Zones and Control-by-Event (CBE) Logic
| Feature | Program Change (Keypad) | VeriFire® Tools (PC Software) | | :--- | :--- | :--- | | | Quick edits, adding a few devices, walk test, troubleshooting | Full system configuration, major changes, backups, complex logic | | Speed | Slower for large data entry | Very fast; uses a full keyboard and mouse | | Convenience | On-site, immediate changes | Offline programming possible; can create a database at your desk | | Capabilities | Complete control via menu system | All keypad functions plus file management, printing, and simulation | | Cost | Included with the panel | Requires purchase of a license from Honeywell/Notifier |
Keep a physical or digital PDF copy of the point-by-point programming matrix inside the fire alarm cabinet for future service technicians and fire inspectors.
Assign a smoke detector to a specific zone (e.g., Zone 5 for the server room).
This is the core logic of the NFS-320. You link input devices to output devices using zones or Boolean logic equations.
If you are looking for specific wiring diagrams, I can help you find those, if you tell me: What are you trying to connect? Are you using old or new SLC devices? What model of NAC device are you using?
The panel allows for detailed program creation, editing, and zone configuration directly from the front panel keypad.
This comprehensive guide breaks down the essential programming concepts, methods, and step-by-step procedures outlined in the official Honeywell Notifier NFS-320 manuals. 1. Overview of NFS-320 Programming Methods
Configure how outputs (NAC circuits) behave in response to input triggers (smoke detectors, pull stations). 5. Critical Programming Considerations
Programming is incomplete until verified via physical loop testing.
Technicians use the built-in alphanumeric display and keypad on the primary display (NFS-320 main circuit board).
