The Signal Panel is a vital game mechanic in TRTF 3.
The Signal Panel has the exact same appearance as the Maintenance Panel from FNAF 3
The Signal Panel has 4 functions for the player to use. 2 of them are actual functions, the other 2 power other functions in the building, and must be fixed if they go offline.
This is one of the systems you must repair. If this goes out, the lights in The Office will flicker. This will cause the player to breathe heavily, and the animatronics will move more rapidly.
Door Lock System
This is the other system you must repair. After a few seconds of a door being closed, this system will break, disabling all doors in the building. If this system breaks, you will be defenseless against Lockjaw, Freddy, Bonnie, and Kitty.
