Certainly at the airport I work at they have 5 buttons and a 'red phone'
The buttons are:
Crash Alarm (Alerts RFFS and Airfield Ops)
Fire Service Auto Alerter - Full Turnout (For Pax Aircraft)
Fire Service Auto Alerter - Partial Turnout (For Cargo Aircraft and smaller aircraft)
Ambulance Auto Alerter - Full
Ambulance Auto Alerter - Partial
The Autoalerters generate an incident on the Fire and Ambulance dispatch system so that they can start dispatching units to the airport.
The 'red phone' is an Auto Dialler straight to Police. It autogenerates an 'Aircraft Emergency' incident log on the Police dispatch system and connects to a dedicated phoneline. The emergency details are then passed to the police who then pass the details on to Fire and Ambulance afterwards.
