Door Interlocking System

Door interlock systems are used to control the entry and exit of personnel and material within a secured area with multiple doors.  The objective is to prevent simultaneous openings of adjacent doors creating what is known as an airlock or mantrap. Door interlocking is different from Access Control.  Access Control verifies the authorization of an individual to proceed through a door.  It typically does not manage the locking and unlocking of adjacent doors. 

Key Benefits of Door Interlocks:

• Enhanced security: prevents unauthorized entry until certain conditions are met. 
• Controlled airflow: in sterile and sanitary applications, they help maintain air purity and restrict contamination between rooms 
• Quality assurance: minimizes production ricks by isolating clean spaces and preserving controlled environments

Designing, building and installing a Door interlock system can prove to be a complicated and difficult task. There are so many variables involved with deploying a Door interlocking system. The number one issue is ensuring that the interlocking scheme between multiple doors is designed properly and allows the movement of personnel and material in a logical and safe fashion. From the mechanical side, there are a wide variety of mechanical components ~ different door types, electric locks, door position sensors and door accessories that need to be integrated into a cohesive system. Incorporating Access Control, Building Management Systems (BMS) and Fire Alarm systems adds yet another layer of complexity.
