1.6.2.3
One Set of EFC301F (Two Readers) – Control of both Entry and Exit
When the security grade is relatively high or the administrator requires the card holders
to get in or out at fixed time or date through specific door, one controller and two
readers are needed. Additional installation of one reader on the side of the door
requires the card holders to swipe the card when exiting and entering. This rule has
more reliable security regarding who can enter and who can exit and the administrator
can also master the entry and exit time of card holders.
1.6.3
Determine the Number of Controllers According to System Structure
Determine how many controllers and network interfaces are required.
Each EFC301F Controller can connect up to two readers. If the system requests installation
of more than two readers, the number of the controller will be increased. You can refer to
Chapter 3 for more details.
