First-Time Internal Audit: What Questions Should I Ask About Physical Security?

I have to do a internal audit for work its my first one, the scope is physical security procedures relating to protecting our IT – so guards, perimeter security like the gates, fences and windows, CCTV, and then the doors to the locked rooms we keep the big servers and network kit in? Can any one help what questions I could ask. Basically I nedd help doing my checklist.
Thanks in advance.
