When the emergency access code is entered the cockpit buzzer sounds continuously for a period of time (company specific but probably 10-30 seconds) in the cockpit. During this period of time the door remains locked. The cockpit occupant can select deny on the cockpit door switch thus denying entry. If deny is selected, the door remains locked. Any further inputs on the cockpit access panel are ignored and the buzzer inhibited for a period of time (company specific but probably 10-20 minutes) If nothing is selected the cockpit door will unlatch for a very short period of time allowing entry.
