AC-A4x Installation and Programming Manual 15
4. Normal, Secure, and Master Users
The AC-A4x series accept up to 500 users and provide entry via the
use of proximity cards and/or PIN codes. Each user is provided with
two code memory slots: Memory Slot 1 (Primary code) and Memory
Slot 2 (Secondary code). For the AC-A42, the two memory slots can
be programmed as proximity cards, PIN codes, or a combination of
both proximity cards and PIN codes.
The way that the two memory slots are programmed determines a
user's access level and also determines the way that the units grant
access in their three modes of operation (Chapter 5).
There are three user levels:
Normal User – A Normal User only has a Primary code and is only
granted access when the AC-A4x is in Normal or Bypass mode.
Secure User – A Secure User must have a Primary and Secondary
codes programmed; the two codes cannot be the same. The
Secure User can gain access when the AC-A4x is in any of its
three modes of operation. In Normal mode, the Secure User must
use a Primary code to gain entry. In Secure mode, the Secure User
must present both a Primary and Secondary code to gain entry.
Master User – A Master User must have both Primary and
Secondary codes programmed with the same Proximity card or
PIN code. The Master User can gain access during any mode of
operation by presenting the Proximity card (AC-A42 only) or
entering the PIN code. (The Master User is convenient, but is less
secure than a Secure User.)
