Area power controller

APC

An APC is an Area Power Controller. These are used to provide power for a sector on the station. To use an APC, somebody with actual access to them, usually the Chief Engineer or an Engineer, needs to swipe their card on an APC to unlock it. Once they do this, there are a few options available to them.

Power: On/Off - Toggles power to the APC
Main Breaker: On/Off - Toggles power to the APC
Equipment: Auto/On/Off - Toggles power to computers, doors, and other electronic equipment.
Lighting: Auto/On/Off - Toggles power to lighting in the area.
Environmental: Auto/On/Off - Toggles power to the ventilation in the area, as well as the Air Alarm.
Overcharge Lighting Circuit: Sends a pulse throughout the lighting circuit, making any lights shatter and send out sparks.
Cover Lock: Engaged/Disengaged: Provides a cover to protect the battery.

Remember, auto power slowly cuts off each breaker when power runs low in this order:

Replacing the Battery

To replace the APC battery, you need an ID with sufficient access to unlock the APC itself.

Swipe your ID and unlock the interface.
Open the panel and disengage the cover lock.
Use a crowbar on the APC to open the cover.
Take the battery out with a free hand and then place in the new one.
Close the cover again with your crowbar, re-engage the cover lock and swipe your ID to secure the interface.
