If they have lights, you can bet they certainly have some vents, otherwise
it will get way too hot inside those vitrines. for the contents.
If they have vents, your problem is solved.
If they don't have vents, maybe the electrical/lighting engineer should
have recommended them before you do.

Geir,
It is a real pleasure to know you as a person who has done a great deal
on hypoxic air venting, I agree that this is the best solution when
evacuation routes are insufficent.
I have two questions about this system, first, while hypoxic air can't
penetrate enough into vitrines, so what about fire protection inside
vitrines? There are some lamps inside each vitrines which may cause fire,
and hypoxic air concentration inside the vitrines is not enough to prevent
fire ignition. On the other hand, it is not possible to transfer the
hypoxic air inside the vitrines, so what kind of fire protection system I
should consider for inside vitrines?
My second question is that I agree that there is no health risk to stay
in low oxygen rooms for some hours, but how does it feel to stay in low
oxygen rooms for a few hours a day over a longer period like museum staff?
Thanks for your kind attention,
Reza

I followed the thread on the sprinkler forum.
Please allow me to forward related article and report you may want to
check.
By the way, are also responsible for the European study of manual
extingsihsrs that Stewart linked to and for the European report on Water
Mist for Heritage applications.
Several museums now apply or plan to apply hypoxic air venting in favour
of FM 200 and similar options, including the Smithsonians First Flag (Star
Spangled Banner) Museum in Washington, British Library London, Library of
Oxford, Historical Museum Oslo, Schloss Schonbrunn Vienna.
While viable, you may not want to apply hypoxic in prevention mode (24/7)
in public areas/exhibitions to avoid responding to all the questions, but
it is the best solution when evacuation routes are insufficent: Hypoxic air
does not allow any fire to start in the first place, so evacaution (if at
all required or for reasons other than fire) is carried out orderly without
a need to hurry.
If you need more information, literature or links I may provide. Would
then appreciate information on your affiliation with your client -
sprinkler system vendor?
Yours
Geir Jensen
