2. It is recommended not to plug/unplug connection terminals frequently when
the system is energized. Be sure to unplug the connection terminals before
starting any relevant welding job.
3. Do not detach or replace any control panel chip without permission, because
unprofessional operation may cause damage to the control panel.
4. It is recommended not to connect any other auxiliary devices without
permission. All non­routine operations must be communicated to our
engineers in advance.
5. A control panel should not share one power socket with any other
large­current device.
6. It is preferable to install card readers and buttons at heights of 1.4­1.5m above
the ground, but the heights are subject to proper adjustment according to
customers’ usual practice.
7. It is advised to install control panels at places easy of maintenance, like a
weak electric well .
8. It is strongly recommended that the exposed part of any connection terminal
should not be longer than 4mm , and specialized clamping tools may be used
to avoid short­circuit or communication failure resulting from accidental
contact with excessive exposed wires.
9. To save access control event records, read data periodically from control
panels.
10. Get prepared countermeasures according to application scenarios for
unexpected power failure, like selecting power supply with UPS .
11. The connection between a card reader and a control panel should not be
longer than 100m .
12. The connection between a PC and a control panel should be shorter than
1200m for RS485 communications. A length within 600m is recommended to
make communications more stable.
