According to the British Security Industry Association guidelines, access control points are classified based on the type of business and the associated security risks. Each grade is assigned to specific protected areas rather than the overall system, allowing for a mix of grades within a single premises. For example, you might have Grade 1 access points in certain areas while other locations may require Grade 4 protection, depending on the specific security needs of your building.

The assigned grade for your access points serves as a valuable indicator of the necessary security level and the recommended technology for each area. This classification helps business owners, installers, and designers effectively address the security requirements while staying within budget.
