3.1.3 Bypass Mode
The left LED is orange.
In Bypass mode, access to the premises is dependent on whether
the controller's Lock Strike Relay is programmed for Fail Safe
Operation or Fail Secure Operation. When the Lock Strike relay is
programmed for Fail Secure Operation, the door is locked until the
star button (*) is pressed. When the Lock Strike relay is
programmed for Fail Safe Operation, the door is constantly
unlocked.
In case of power failure, once the power is restored, the controller
returns to Normal mode for security reasons.
3.2 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.
