I have been told that any device installed into a condo or townhome firewall or ceiling must be able to withstand the same 2 hour fire rating as the wall itself. I work for a company that designs inceiling and inwall speakers. Normal construction is a plastic frame or baffle with a steel backcan.
Can anyone tell me what specific UL and/or NFPA standard is invloved with this? Or, what the 2 hour test consists of, i.e.; direct flame contact at what temperature?
Thank you in advance for any help or guidance you can provide.
