I have been asked to turn the valves so they don't protrude further from the wall than the standpipe does (leaving clearance for firefighter use) and run the standpipe down to the floor so the cane can find the bottom of the pipe. I have had an AHJ accept a piece of 1" that does from the bottom of the standpipe to the cap on the 4" to act as the detection. I don't think bollards would be required or at least they haven't been around here in North Carolina yet.
