Installed a motion sensor upside down and didn't realize for 3 hours

I was at a house in Arlington last Tuesday, wiring up a new DSC panel in their basement. Stuck a motion sensor on the wall, felt pretty good about it, then went to test it and nothing happened. Turns out I had it mounted upside down the whole time, so the pet immunity was pointing at the ceiling instead of the floor. Felt like a total goof when I flipped it and everything worked perfect. Anybody else done something like that on a job?

My buddy Phil did that with a garage door sensor, took him four hours to notice.

Man that's rough, I feel for the guy. Four hours is a long time to be messing with something that should've clicked way sooner. Hopefully he got a good laugh out of it eventually.

Did he at least get a beer out of it? Would've earned one after that.

Did you at least check the polarity on the jumper settings before testing it again or just flip and pray? I've done that once with a dual-tech and it turns out the sensor was fine but I had the vertical adjustment wrong the whole time. Would've saved myself the walk of shame if I'd read the manual first lol.
