Reader Operating Modes
The FD-777A reader has two installation modes:
Standalone Mode
, and
Wiegand reader mode
.
Below is a brief explanation of each mode. Refer to the programming section for details about
selecting each mode.
Standalone Mode:
By default, the FD-777A is programmed for Standalone Mode. In this mode, all the users
and other programming options are maintained within the reader and no additional
controller is required. The lock and all other inputs and outputs are connected directly
to the FD-777A.
Wiegand Reader Mode:
In Wiegand reader mode, a separate third-party Wiegand Access Control panel is
required. When you register your face on the FD-777A, an enroll ID is required and it is
then sent to the control panel as Wiegand card data. The control panel maintains the
users and programming options and makes all the access control decisions. The locking
device and all inputs and outputs are connected to the third-party control panel.
