Wood Firewall Breakaway Connectors

[Budding_SE]

Has anybody ever designed a Wood Firewall? What type of connectors do you use for it to breakaway? I am using a wood wall as a bearing wall. My headers sit on the stud pack in the wall. What type of connection could I use for the headers to break away in the event of a fire? The wall is 2 hr rated.

Thank you in advance for your response

I have and inspected hundreds. Send me a sketch. generally you use a 2" gypsum shaftwall which fully separates the occupancies with the wood walls 3/4" away from the shaftwall.
Is this a townhouse?
