We are designing a new fire rated pet door to be installed in an existing residential attached garage fire wall or door.

 

I would like to know what design requirements would be required to meet UL/NFPA for a Hold open, sliding, 20 minute fire rated assembly as is shown in the attached video.

 

I believe it does not have to have hose stream test. Any reference to codes would be greatly appreciated.

 

Thanks in advance

 

Rick
