10.4 Master­slave function ê
Two devices, a master and a slave, both controlling the same lock, are connected by RS232/RS485/Wiegand.
1. The Applications of the Master and the Slave
1) Record storage:
By default, the master status is exit and the slave status is entry. The records of entry and exit are both saved
on the master.
2) Anti­Passback function:
Whether to perform the anti­passback function is determined by the latest record of the user's entry and exit.
With this function, the exit record must match the entry record. The function supports "Out", "In", "In Out",
"None and save " or "None". anti­passback. By default, the identification status of the master is exit and that of
the slave is entry, so if " out anti­passback " has been set and when the last record of the user's entry is not
"entry", the system will prompt anti­passback refusal" and refuse to open the door if the user wants to exit.
The logic is the same with "out anti­passback" and " in out anti­passback".
For example, now A wants to exit.
① If the last record for A is not entry, the device will prompt anti­passback refusal and refuse to open the door.
② If the last record for A is entry, after the fingerprint identification is passed, the device will open the door.
3) Alarm function
If the slave is equipped with alarm function, when an alarm incident occurs, the slave will forward it for the
master to process. There is no such function on device that is not equipped with alarm function.
