The NFS-640 provides two methods for field-programming the control panel:
• Using the built-in “Program Change” interface
• The VeriFire™ Tools Programming Utility
The benefits of each method are listed below:
How to Enter a Password
The control panel provides two types of selectable passwords:

Listed below are uses and the factory-setting for each password type:

In Program Change or Status Change, the control panel does the following:
• Activates the System Trouble relay
• Shuts off the panel sounder
• Flashes the
SYSTEM TROUBLE LED, which continues to flash while programming
For security purposes, you can change your passwords. To do so, follow the instructions in “How to
Change a Password (3=passwd)” on page 26.
Note: The Read Status selection, which does not require a program password, is covered in the NFS-640 Operations
Manual.
Note: The NFS-640 continues to monitor and report alarms in programming mode, except in autoprogramming.
