Vault generator

The  is an electro-mechanical device used for converting mechanical energy into electrical energy for powering the Vault. Generators are a component of the electrical grid. A common hazard with generators is a fire started by an exploding generator. In the case of a fire, ceiling mounted fire sprinklers douse the fire with flame-retardant liquid which smothers the fire and prevents the fire from spreading. A fence surrounds the generator preventing residents from accidentally falling onto the device. These generators are used in the Vault-Tec Vaults.

Vault 101
Vault 101 has three generators: one on the Reactor Level and two near the Main Entrance.
