Maintenance Panel

The Maintenance Panel is a device of the Five Nights at Freddy's series, first introduced in Five Nights at Freddy's 3.

Five Nights at Freddy's 3
It can be activated on the far-left side of the Office. It allows the player to reboot the audio devices, camera system, ventilation, or all at once should they get errors in any of them.

The maintenance panel then returns in Five Nights at Freddy's VR: Help Wanted, as one of the core elements in the FNAF 3 section once again.

Audio Devices
Audio Devices allow the player to play a sound byte of BB's laugh in different rooms in order to lure Springtrap away from The Office and to other rooms. The audio does not play on the vent cameras, and Springtrap may be unaffected if it plays in the same room that he is currently in or if he is in a vent when the audio is played.

After a certain amount of uses, the Audio Devices will need to be rebooted, during which it cannot be used. The number of uses before the player is required to reset it decreases as the nights progress, eventually being reduced to two uses by Night 5 and onward. An error can also occur after Phantom Mangle screeches.

Camera System
Occasionally, the Camera System will need to be rebooted if it is used for too long. The Monitor will usually be black and static, with the error message, "Video Error" displayed in the top-left.

This means the player can't see through the cameras to see Springtrap's location, allowing him to move with impunity. Some phantom animatronics can still be seen and triggered. Audio can still be played, however, to lure Springtrap away, to give the player time to reboot safely.

Ventilation
The Ventilation will shut down periodically, or when the player is jumpscared by a phantom animatronic. If the ventilation is offline, The Office will flash red, and the player's vision will begin to fade, alternating back and forth. This will give Springtrap an opportunity to move around more frequently and attack when the player's field of vision turns black if he is close (i.e. peeking around the corner of the doorway). The player will also see multiple Springtraps on the cameras, however these are just hallucinations.

When jumpscared, the fading will start immediately; when the ventilation shuts down normally, the alarm will sound and the Office will flash red, then the fading will start to occur several seconds later. The player can still access the cameras and use the audio to lure Springtrap far enough away to reboot the ventilation safely.

Five Nights at Freddy's: Sister Location
The Maintenance Panel makes its second appearance in Five Nights at Freddy's: Sister Location as the Breaker Control Box interface. It makes its first appearance when HandUnit fails to reboot the power, thus assigning the player to manually reset every breaker in Circus Baby's Entertainment and Rental. Oddly, this one shares the same model as the monitor in the Private Room. The Breaker Control Box interface has one sole function, namely to reset the breakers across the building. Each breaker takes approximately five seconds to reboot. There are eight breakers that must be rebooted - Circus Control, Circus Gallery, Funtime Auditorium, Ballora Gallery, Parts & Service, the Elevator, and two areas from Five Nights at Freddy's 4 labelled "Obsv.1" and "Obsv.2".
