7.2
Function ‘‘Door open‘‘
In the case of the standard lock control mode, after activating the "Door open" function, the release of the lock relay and
the buzzer are activated (unless disabled by configuration). This state lasts until the door is opened, but no longer than
the time set by the "Lock activation time" parameter. Then the lock output is deactivated and the standard function is
terminated.
In the case of the toggle lock control mode, after activating the "Door open" function, the relay output toggles and the
buzzer is activated (if it is not disabled by the configuration). The acoustic signaling lasts as set. The relay output remains
unchanged until the next activation of the "Door open" function.
In the case of the pulse lock control mode, after activating the "Door open" function, the relay output is activated for the
time given by the parameter Pulse width (ms).
In the case of the standard lock control mode, reading a valid card during lock activation will cause a new lock timing.
Online authorization
If the reader module reads the ID card during the "Door open" function via the communication line (in online mode) and if
the read ID is not valid, it is signaled by an acoustic signal "invalid ID" regardless of the configuration of the acoustic lock
release message.
7.3 Permanent lock release based on valid time schedule
When this function is set, the lock is permanently released during the validity of the respective schedule, the reading of a
valid ID is reported via the communication line (in online mode). When the lock is permanently released, the alarm state
of the forced door does not occur.
The setting of the permanent release of the lock according to the time schedule and the toggle lock control mode are
mutually exclusive.
7.4 Function of ID with flag
It is possible to set a flag for each ID, which will cause an alarm ‘‘ Alarm - ID with the flag ‘‘ when reading the appropriate
ID (and will activate the alarm output for a defined time).
