Secret Menu inside a Notifier NFS640 fire alarm panel 

Correct. I read it in the documentation later on. Seems like it was never in previous documentation I flipped through over the years.

You could pull the loop OR you could disable the CBE that follows all modules in the disable menu.

Upload to the laptop with verifier tools then download it back to the panel. That will clear the program corrupt 99.9% of the time. If you don't have verifier tools or if you are in a remote area, there is a way to do it over the internet.

I got distracted with Smartwatches, then after I got the "vid" my priorities changed. You need to know more about notifier ? Contact me if you like.

@@firealarmapprentice4517 would any of these commands work on the afp-300/400? Been trying to connect mine to older verifier tools without much luck

@@mimi2 Oh you got me there. I barely remember the 400 because they didn't last long due to RAM /ROM issues. The the serial port rs232 or did they use a 5pin ? Make sure you have RX TX properly connected. Remember, its NULL meaning RX > TX and TX > RX.. the physical connection.

@@firealarmapprentice4517 What are all the parts needed to build a NFS2-640 system?

@@hilo2-est3-elev Parts? You mean for text alerts? Google sheets population?

I mostly use minicom. More than just a printer.. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kc0IfUopZmQ.html

any help me for i have NFS-320 Panel and all module pull station and smoke detector red lights blinking i didnt understand whats going on now i just turn off the power breaker .also how to solve Invrep in all devices

I can help but I need to be at the panel or minimum need much more detail. The LEDs blink, that is normal.@@VocalSongs175

Invrep appear on the panel screen and all devices blicking red light smoke,pull station all devices . also we try smoke but not respoding also pull station not working , we also changed Module with new some with same address but still same @@firealarmapprentice4517

?? Its really a lookup.. not decryption.

Not sure, I will re watch it. There are some menu items I wanted to publish, then I said to myself.. "maybe not"

I agree mostly to your point but I would add this.. fire alarm technicians (technologists) or a qualification exceeding that of just an inspector should be the requirement for opening the hood and looking at the code.

i believe looking like being able to pull the programed information should be available to all techs on inspection (programed information can get corrupted though it could be found by other means its still a thing the industry needs to look at) . programing changes is like changing a device location and should require a verification. so i don't see harm allowing technicians to work on them but all resources should be available from manufacturer. programming fire panels (like setting up a router) is seen to be a hard thing its not " if information is available" and is made to do so.
