The door interlocking system is used to control the entry of personnel to a secure area such as a cleanroom where dust or small particles may be a problem. The principle is generally well understood. In its simplest form, the door interlocking is composed of 2 to 12 doors that are electrically interlocked in such a way that the doors cannot be opened simultaneously. The door interlocks are used in a variety of situations but in essence they are there to control the unwanted passage from one area to another.
Interlocking System achieves in prevention of process area contamination by:
- Preventing simultaneous access of doors/rooms
- Ensures that when one door of a room is OPEN, then all other doors in that particular room can’t be opened.
- Programmable delay between each door openings to maintain required pressure.
- In case of emergency, an override key is available on a push button module to open door(s).
