Cold Smoke Seal

In regard to whether it matters or not, Kurnal gives a good steer here, it depends on the layout and also whether high risk stuff is in either immediate area.
I presume we are talking electronic access control here. I have a similar situation, in my case the doors are heavy 60 mins, so  robust furniture was required.
Only way to combat this was L1 fire detection, giving good warning before smoke build-up. Evac chairs & buddy system for restricted mobility etc.
In other words, mitigate the risk to persons cos you're gonna get smoke leakage.
Believe it or not, this is a major control room!
