Door Inter Locking System is used to control the entry of personnel to a secure area such as a clean room where dust or small particles may be a problem. The System ensures that when one door for a room is Open then all other doors in that particular room are closed. The System is composed of 2 to 12 doors that are electrically interlocked in such a way that the all doors cannot be opened simultaneously. Door Inter Locking System is featured with programmable delay between each door openings to maintain required pressure and in emergency an override key is available on a push button module for opening the door.
