In the security room (2nd floor, the "Security" door) there is a lightswitch that disables all internal lights, then dimmer "emergency" lights are turned on. Also, there are three terminals in there, each of which is tied to a trigger_camera. I think they track an invisble object, but not always. The custom wad is just for the sign out front. Hostages are in the president's office (adjacent to the security room) and in the basement vault. (Stair access in middle-south, bank faces east) The stairway the T's start in goes up to the roof, and the skylight can be shot through, of course

This was compiled with -fast vis, because I have 62 direct lights (I know, a lot).
Let me know if there are any inconsistences (i.e. brick texture on an interior door) or improvements (to put in ambient sounds, etc.)
Other than the bank.wad, you need the standard halflife.wad. Don't forget your nightvision and flashlight when the lights go out!
