Selection Notes
The key cylinder (key number 455) restricts who can change the O-I state, which is the reason to pick this over the handle-operated XALD134 covering the same function: use XALD144 wherever mode selection needs to be reserved for authorized operators, and XALD134 where free access is acceptable.
