How far should the position sensor of a door access point be mounted to activate when the portal is opened?

• A. One inch
• B. Two inches
• C. Three inches
• D. Four inches

Answer: (B)

The position sensor of a door access point is typically mounted to activate when the portal is opened at a distance that allows for reliable detection of the door's movement. A two-inch distance is commonly considered optimal because it strikes a balance between ensuring that the door is adequately recognized as opened while minimizing the risk of activation from slight movements or vibrations. This placement helps to prevent false positives that might occur if the sensor were set to activate at a greater distance. Additionally, having the sensor too close may result in missed activations if the door is not opened wide enough for the sensor to trigger. Therefore, mounting the sensor about two inches away allows for effective monitoring of the door status, ensuring that the access control system functions properly without unnecessary errors.
