The position sensor of a door access point should be mounted to activate when the portal is opened no greater than how many inches?

Mounting a position sensor of a door access point to activate when the portal is opened no greater than two inches is critical for several reasons. This specification ensures that the access control system can respond quickly to changes in the state of the door. A two-inch threshold allows the sensor to detect when the door is ajar, helping to prevent unauthorized access and ensuring safety protocols are maintained.

If the activation threshold is set too high, there may be a delay in response, increasing the risk that a door could be tampered with or that an access event could go unnoticed. Additionally, setting the activation distance to two inches helps in accommodating minor shifts or movements of the door without triggering false alarms or unnecessary activations.

Other options, with thresholds of one inch, three inches, or four inches, would either be too sensitive or not sensitive enough, potentially compromising the efficiency and reliability of the electronic access control system. Therefore, a two-inch activation distance strikes the right balance for effective performance in maintaining security.
