Honeywell Notifier Nfs-320 Programming Manual Jun 2026

During or immediately following a programming session, the NFS-320 may generate trouble codes on the LCD screen. Here is how to resolve the most common manual-documented issues: Invalid Reply / Type Mismatch

What specific (like elevator recall) are you trying to set up?

Let’s walk through a common task using the instructions:

Assign a (001 to 999) to link the device to an output.

Built-in 6.0 A integral power supply with a battery charger. 2. Accessing the Programming Interface honeywell notifier nfs-320 programming manual

Assign the exact functional profile (e.g., PHOTO for photoelectric smoke detection, HEAT for thermal detection). Incorrect type codes generate an "Invalid Reply" trouble code.

Assign the NACs to global or local software zones so they activate when an input triggers. Advanced Logic: Control-By-Event (CBE)

Assign the control type (e.g., STROBE RELEASING or TEMPORAL ).

Select whether you are scanning a clean loop or adding to an existing installation. During or immediately following a programming session, the

: Select 1 for Basic Programming, then select 1 for Auto and Program.

1 Signaling Line Circuit (SLC), supporting up to 318 intelligent addressable devices.

Users can edit points and settings directly from the front panel's QWERTY keypad while the system continues to provide fire protection.

This guide serves as a comprehensive overview of the programming principles, methods, and configurations found in the Honeywell Notifier NFS-320 technical literature. Introduction to NFS-320 Programming Architecture Built-in 6

Up to 159 intelligent detectors (ionization, photoelectric, thermal, or multi-sensor). Up to 159 monitor/control modules. A total of 318 addressable devices on its single SLC loop.

Keep copies of the .vft database file securely stored on a cloud drive and on-site inside the panel cabinet enclosure.

Configure global options, such as AC fail delay times and local buzzer behavior. 3. SLC Loop Point Programming

To customize device behavior (e.g., changing a device from a smoke detector to a heat detector or changing its address), you must use the edit function.
