Hotel Inspection - Addressable nightmare; testing two smoke shutters that drop to prevent smoke from the lobby/atrium getting into the 2nd floor hallway. Naturally I assumed that the smoke head on the other side would trigger it. Negative.
Yes, we could have looked through the programming but that requires digging up all of the device numbers - in this case usually that means finding the module or just scrolling through hundreds of them in the panel programming. Easier to just start tripping things.
As you can see, one of them didn't work. After determining that no one really knew who was supposed to deal with them I poked around above the ceiling and found the trigger mechanism - it's a solenoid that releases a cable which holds back a giant ratcheting mechanism - hare trigger barely describes it. It was too tight and the solenoid couldn't do it. I got it working, sort of - the shutter was in need of adjustment and maintenance - we notified the vendor.
This doesn't "fail" the inspection overall - but it's not an insignificant problem.
