Description:

The door interlocking 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 principle is generally well under-stood. In its simplest form, the door interlocking is composed of 2 to 12 doors that are electrically interlocked in such a way that the all 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.

Door Inter Locking System achieves in prevention of process area contamination by

• Preventing simultaneous access of doors/Rooms.
• Ensures that when one door for a room is OPEN then all other doors in that particular room are closed.
• Programmable delay between each door openings to maintain required pressure.
• In Emergency an override key is available on a push button module for opening the door.

Push Button Station

The push button is used to open the door .when the button is pressed it sends a request to the controller to realize the door. The Push Button module is provided with GO,WAIT message status display.

Features:

• Elegant look Legrand Silver painted plastic Bezel/Face plate.
• Indication facility for Door entry permitted / prohibited.
• Support an entry switch for opening the door.
• Long Life BAR LED for door open/close indication.
• Elegant look Silver painted plastic Bezel with appropriate curvature to prevent resting of dust & powder.
• Easy mounting arrangement for fixing on Doorframes or on Wall.

Emergency Push Button Station

The Emergency Push Button module is an input device, which is used to take ‘OPEN ALL DOORS’ request from the user. The Emergency Push Button module is interfaced to the controller, from where the request is eventually fed to the Controller module.

Features:

• Elegant look Legrand Silver painted plastic Bezel/Face plate.
• Support an push button switch for opening the all doors.
• Elegant look Silver painted plastic Bezel with appropriate curvature to prevent resting of dust & powder.
• Easy mounting arrangement for fixing on Doorframes or on Wall.

Electromagnetic Lock

A magnetic lock is a simple locking device that consists of an electromagnet and armature plate. By attaching the electromagnet to the door frame and the armature plate to the door, a current passing through the electromagnet attracts the armature plate holding the door shut

The magnetic lock relies upon some of the basic concepts of electromagnetism. Essentially it consists of an electromagnet attracting a conductor with a force sufficiently large enough to prevent the door from being opened.

Electric Striker

An electric striker is an access control device used for doors. It replaces the fixed strike faceplate often used with a latch bar (also known as a keeper). Like a fixed strike, it normally presents a ramped surface to the locking latch allowing the door to close and latch just like a fixed strike would. However, an electric strike's ramped surface can, upon command, pivot out of the way of the latch allowing the door to be pushed open (from the outside) without the latch being retracted (that is, without any operation of the knob) or while exited the knob or lever can be turned to allow egress from the secured area.
