The code detectors are message detectors built into the Lumon Industries Severed Floor elevators and staircases. They can detect all messages and codes.

These detectors are first mentioned in Half Loop. Mark describes them to Helly as “metal detectors for written symbols”[1]. In the episode, when the code detectors are triggered the hallway lights start flashing red and white and Graner is alerted.
