I have a 1 hour rate fire/smoke partition. It is allowable to have a 20 min rated door in this opening or is a 45 min door required. Any table reference I could use as back up would be helpful.
Thanks in advance for any help.
What building code has the city adopted and year??
What type of business or use?
IBC 2015 is the adopted code.
Door is new construction.
Use is psychiatric hospital
Based on my research the if the door is not "potential for severe fire exposure from the exterior of the building" is is OK as a 20 min door and does not need to be rated for 45 min.

Sorry there no such thing as fire/smoke partition in the IBC.
What is the function of the wall the opening is in?
I have read all the posts. Please refer to these code sections:
T-716.5 of the IBC, just apply whatever situation you are in.
I have a 1 hour rate fire/smoke partition.
Is this a corridor wall or what is the rated wall there for??
If an opening in a corridor wall, than yes twenty minute,
If the wall is there for another reason, depends, sometimes it has to be an one hour door
If just a standard smoke partition a 20 min door may work. However, if the wall has a FRR component a 45 min door and frame will most likely be required. Additionally, the door assembly should require listed smoke gasketing. If this mental health facility obtains Medicare and Medicaid funding they will have to adhere to CMS rules and follow the 101 LSC - 2012 Ed. requirements as well as the local building codes. refer to NFPA 80 and NFPA 105 2010 Ed.
Rule of thumb is the door is rated 75% of the wall rating. If I where you I would consult your AHJ about this. Hate to guess 20 minute is okay only to have your AHJ make you pull and replace.
