At work I find the security folks using FPL to provide 24 volt power for Video Surveillance cameras and other non life safety systems. I believe this is a violation. FPL should only be used for Fire Alarm circuits and CPL is for security systems. The techs say they have been practicing this for 15 years. The Red is suppose to make FIRE circuit easy to identify. If everyone uses it you can not distinguish between the different types of systems/circuits vs. life safety/non-life safety.
My question is can you use FPL on any Class2 power supplies? or is it limited to FA systems?
This might help you out. Years ago you could use CL for FA systems as they both have the same voltage & temp ratings. I’ve also seen FPL in many different colors, not just red.
A long time ago, when we had an ADT Install done at our house, they used RED FPL for the keypad run… However, the fire circuit on the system was ran with FPL.
Please forgive my ignorance in this meaning of the code, In Chapter 800 NEC - NFPA 70, it state the cabling must be listed. I assume listed means, listed for Communication installations, which implies not to use FPL; Exception: is if you are connecting FA equipment to the Security system.
The Figures in the Reference document above supports this theory. you can use CM in place of FPL, but you can not use FPL in place of CM.
