Internal Relay activation on Access Granted result
Description
If the result of the access rights check is successful, the internal relay may be optionally
activated, for example, to directly trigger a door switch.
The duration of the activation of the internal relay can be modified by a specific configuration
key.
Access control installation using internal relay offers a lower security level, than an installation
with a central access controller. In case of a centralized access, the decision to open the door is
taken by a central host, thus making the process more secure.
