An emergency override system, also known as cable override, automatic emergency override, or emergency cable override system, is a warning system that is arranged and used by cable television operators and emergency management officials to warn cable subscribers of imminent or ongoing threats or other emergencies such as severe weather, criminal activity, or missing children.^[1]

Activation process and additional functionality

To initiate an override, an emergency management official, using a telephone, inputs a PIN in order to override all channels for cable subscribers in a given area and deliver the emergency message. Once the alert message has ended, the official hangs the phone up to end the override.

Some override systems are capable of solely overriding the audio feed for cable subscribers as opposed to both the audio and video feeds. One example of such utilization was in Troy, Ohio, where local police used it to warn residents of a robbery where a group of burglars stole five handguns from a hardware store.^[2]
