4.2 User Levels
AC-Q4x series access control units accept up to 500 users and provide
entry via the use of codes. Each user is allocated two memory slots:
Memory Slot 1 (primary code) and Memory Slot 2 (secondary code).
The way in which the two memory slots are programmed determines
a user’s access level and also establishes access is granted for each of
the three modes of operation.
There are three user levels:
Normal User
A Normal user only has a Primary code and is granted access only
when the controller is in its Normal or Bypass mode.
Secure User
A Secure user must have a primary and secondary code assigned,
and the two codes must not be the same. The Secure user can
gain access in any mode of operation. In Normal mode, the
secure user must use the Primary code to gain entry. In Secure
mode, the Secure user must first enter the Primary and then the
Secondary code to gain entry.
Master User
A Master user must have identical Primary and Secondary codes
assigned. The codes are entered with the same proximity card or
the same PIN. The Master user can gain access during any mode
of operation by entering the code only once.
