CALIX is the machine intelligence controlling the systems of Secret Vault, developed by Vault-Tec. CALIX is what ZAX originally was planned to become: an advanced computer designed to be implemented in the Vaults. CALIX controls many systems of the Vault, including robots and researches. Shop-Tec, a robotic trading machine, is probably CALIX's integral part.
When a conflict begins in the Secret Vault between Blake and scientists, a major explosion take place, which heavely damages the Vault and its systems. CALIX partially malfunctions and is unable to control security robots of the Vault. Soon, chaos starts in the Vault, further continued after the Super Mutants attacks the Vault.
The Initiate of the Brotherhood of Steel could recieve some background infromation about the Vault from CALIX, though it denies the access to major secrets, like laboratory's purpose. The main access terminal of CALIX was later destroyed by attacking Super Mutants and all it now able to do is electric damage to the Initiate. CALIX was destroyed when the whole Vault was blown up.
