California 2-hour party wall question

[cda]

"So with H Channel
How does one side fall down and on stay up??"

The assemblies designed as firewalls have aluminum clips on both sides to connect the gypsum board to the structure. If one side catches the aluminum clips on that side melt so the framing can fall away without pulling the gypsum board down with it.

Well isn't that interesting, learn something everyday, And I have been looking at Densglass two hour walls/ not my responsibility, for awhile and I was told the clips were there for another reason.

Thanks!!!

Or you could build separate masonry walls (or other load bearing walls) for each unit with a 1/4” gap. Several ways to skin this cat without the clients friend calling the inaccurate shots.

Completely different construction type I'm working with, IIB, regardless, what does the verbiage "under fire conditions," mean in the context of the code? How does this apply if the use of double fire walls per NFPA 221 is utilized for separation?

How does this apply if the use of double fire walls? it does not..."Under fire conditions code" typically refers to a set of safety protocols or procedures that must be followed in a situation where a fire is actively burning, outlining actions to take to ensure the safety of personnel and minimize damage.
A two-hour wall will alter the timeline (procedure) on exiting the building.
