If a door on the access control system is held open for an extended period of time the door control will give an audible indication; short or long beeps; that it is being held open. Holding a door open will also cause a warning message to be displayed in the Security Services control room.
If you require an extended door opening period; either permanently or temporarily (perhaps as a result of injury) contact Security Services (security-office-uob@bristol.ac.uk) who can extend the access opening time for all access controlled doors.
If the time extension is temporary please remember to advise Security Services to remove the extension when it is no longer required.
