ACCESS CONTROL SYSTEM
The following figure shows the main elements involved in an access control system
and the interactions between them:
Figure 1.
Access control system elements.
IWAC
(
In-Wall Access Control
): NFC reader for access control that is installed
outside the room.
Securel
: final element acting on the lock when granting access from IWAC. It
is installed inside the room.
In the idle state, Securel will keep the electric strike locked to prevent the
door opening. When the
Open
command is correctly received from IWAC
(access granted), Securel will release the lock for a while to open the door.
BMS
(
Building Management System
): computer system that assumes the
integral automation of the building.
Z-Access
: application that allows employees to record access cards. In
addition, by means of a specific module of the BMS system, permits the joint
coordination of the different IWAC and the notification of certain events.
NFC card
: passive element for accessing to certain rooms.
As indicated before, for security reasons, the communication between IWAC and
Securel is encrypted.
Both IWAC and Securel are connected to the KNX bus.
