Access Control SY400 vs Suprema Security groups

Security groups decide which doors a person can use, but the SY400 and Suprema controllers work out the result differently, so the same group settings can allow access on one and deny it on the other. This matters for the SY400 when it is Online and access is authorised at the server.

The table below shows, for a set of security groups (SG1 to SG5), which doors each one allows or denies and whether access is granted. On the SY400, a door is allowed if any security group grants it, and denied only when no group does. The Suprema applies the permissions differently, so a door that the SY400 would allow can come out as denied.

Read the relevant table for the controller you are using to work out whether a given combination of security groups will let someone through.
