This sophisticated door interlock controller allows 2, 3 or 4 doors to be interlocked to restrict or control entry to and from areas that need to be secured against two or more doors being open simultaneously. Two fundamental operational modes are available: Mode 1 Keep all doors closed but unlocked, when a door is opened all other doors are locked. Mode 2 Keep all doors closed and locked, unlock a door upon request. The system comprehensively caters for use with any kind of door lock and any kind of door even including powered doors, roller shutters, traffic bollards etc.. New features include the ability to configure the system in a 2 door / 3 door combination which effectively creates two separate interlocks sharing a common door, plus a privacy facility which allows two doors within the system to be locked at the press of a button preventing either of the two doors being opened again until the privacy button is pressed again - ideal for controlled change rooms.
