An emergency override system, also known as cable override, automatic emergency override, or cable television interrupt system, is a warning system that is arranged 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 occurring in a locality.^[1]

History[edit]

Activation process and additional functionality[edit]

To initiate an override, an entrusted official, usually an emergency management official, inputs a PIN on a designated telephone in order to override all channels for cable subscribers in a given area before delivering the emergency message.^[2][3][4][5] 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 the functionality to warn residents of a robbery where a group of burglars stole five handguns from a hardware store.^[6]
