• In the Operation chapter, “code” refers to a PIN code or proximity
card depending on the unit you have.
• Memory slots can be a proximity card or PIN code depending on
the unit you have.
The AC-A4x series have three modes of operation:
Normal mode – Mode LED is green
Normal Mode is the default mode. In Normal mode, the door is
locked until a Primary code is presented to the controller. Special
codes such as “Open Code” and “Auxiliary Code” are active in
Normal mode (see Sections 11.3 and 11.4).
Bypass mode – Mode 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 for Fail Secure Operation.
When the Lock Strike Relay is programmed for Fail Secure
Operation, the door is locked until the door bell button is
pressed. When the Lock Strike Relay is programmed for Fail Safe
Operation, the door is constantly unlocked.
Secure mode – Mode LED is red
Only Secure and Master Users can access the premises during the
Secure Mode. A Secure User must enter a Primary and a
Secondary code to gain entry. After entering the Primary code,
the Door LED flashes green for 10 seconds, during which time the
Secondary code must be entered. A Master User only needs to
present the Proximity card or enter the PIN code once to gain
entry.
