Valid user code
A valid user code is 5-digit long. You cannot use "00000" as a code; it is reserved for the
system default setting.
A total of 49 user codes are supported by the system.
Door open
Each valid user code entry is presented by the magnetic lock LED (yellow) glowing (see
Figure
If another command is issued during the door open condition, the new command will
override and the system will perform accordingly.
All these events are logged in the EEPROM and can be seen through the GUI.

Physical intrusion
The system has been designed to detect physical tampering. Four jumpers have been
provided on the board that determine the tamper condition.

There can be various cases of tampering based on the 4 jumper settings. All are supported
by the system and the buzzer is always on, in the event of tampering.
For details on the tamper detection circuit and design refer to STM1403 data sheet.
Error conditions in user mode
There are various error states for this system, as explained below. For each of the errors
encountered the red error LED glows (see
Normal or no tampering condition
This is the default status, when both the NL jumpers (JP2, JP4) are closed and both the
NH jumpers (JP1, JP3) are open. The buzzer is off.
Tampering - normal low
This is the tamper condition when either or both of the NL jumpers (JP2, JP4) are open
and both the NH jumpers (JP1, JP3) are open. The buzzer is on.
Tampering - normal high
This is the tamper condition when both the NL jumpers (JP2, JP4) are closed and
either or both of the NH jumpers (JP1, JP3) are closed. The buzzer is on.
