Specification and Installation of Plenum Devices

[Nitrobunny]

This is concerning a project in California that went through plan check and approval in 2006. I am looking for the specific code that requires installation of plenum rated devices (fire life safety) to be installed. I know the NFPA 262 and NFPA 90A address plenum and cabling and I understand that NFPA 255 concerns testing of such devices but I need to find the part in the code where it requires installation of these approved devices in a plenum space.

Thank you for your time

I can't remember ever seeing a fire alarm device other than cable that had a plenum rating. I just looked over System Sensor's duct detector spec and install sheet and the word plenum is not on it. Those get installed in plenum areas a lot and they are made of some form of plastic or poly something.

And sorry I don't know the answer to which code might call for it.

What kind of devices are installed in the plenum space, or are you just talking about cabling?:-?

Clarification would be needed as far as to what "Devices" this is referring to. Also, if it is referring to initiating devices a call to the Manufacturer might help. Also NFPA 90A & 90B for code references.
