Elves used to get a free perception check to notice secret doors if they were wihtin 5' of them, this was taken out.
Dwarves DO get a free perception check to notice secret doors if htey are within 10 feet of htem sand it invovles stonework.
So unless the person is searching an area, or a dwarf and the door invivles stonework, (it takes a move action to search a 5' x 5' square) he would not notice the secret door even if he rolled a 100 on his quick perception check from the doorway. He is getting a general feel for the room rather then searching specific things.*
*Some people will disagree and say that the one perception should allow it with a -1 for every 10' away. I disagree, I would allow them to seach a square for secret doors from 40' away at a -4, but they would have to declare they are spending that move action searching that square.
So if a person stood in the middle of a 20 x 20 room and spun around in a circle slowly looking for secret doors I would let him make a perception check at -1 (10 feet from a wall)and it would take him 16 move actions to check the 80 feet of wall. I would not let him walk into the room make a percepption check as a move action and note three secret doors even if he had a +100 perception.
