1. Cautions
12
3
Please note the following cautions. Mis-operation may lead to personal injury or
equipment failure:
1D o not energize the system before installation is complete; never carry out
installation activities when the system is energized.
2A ll peripheral devices must be grounded.
3T he conduits of wires under relay must be matched with metaled conduits, other
wires can use PVC conduits.
4I t is strongly recommended that the length of exposed part of any connection cable
should not be longer than 4 mm. Professional clamping tools may be used to avoid
unintentional contact of exposed wires to avoid short-circuit or communication failure.
5I t is recommended that card readers and buttons be installed at height of 1.4m-1.5m
above ground.
6I t is recommended to use the power supply for control panel, and external power
supply for each lock.
7T he appliance shall be installed and wired in accordance with national electrical
code and by qualified personnel only.
Descr iption of n or mal w or k ing state:
Connect the system to the power supply. If the system works properly, the POWER
indicator (red) is lit constantly and the RUN indicator (green) flashes.

Location of DIP switch
Set RS485 address through DIP switch:
1) Place 1-6 on DIP switch are for setting the number of control panels when communicating through RS485, it is adopted for binary coding,
and little endian, the address represented by place 1-6 are shown as figurue(5-1).
2) Before setting the address, please keep the system power off. Jump place 1-6 to desired status. The address number cannot be the
same as another one in the network. For example: to set the device number as 39 (39=1+2+4+32), the corresponding RS485 code is 111001,
then Jump place 1,2,3 and 6 at “ON” status.
3) Place 7 is for restoring factory default settings. Jump it for three times within 10 seconds and restart the system. All information in
control panel will be cleared and the system restores factory default settings.RAM
4) Place 8 is for setting terminal resistance when communicating through RS485. Jump it at “ON” status, then it is equivalent to having
a terminal resistance of 120 ohm between 485+ and 485-.
Figure(5-1)
Restore factory setting
RS485 terminal resistance
3) When the Electrical Lock is connected to the Access Control System, you need to parallel one FR107
diode (equipped in the package) to
prevent the self-inductance EMF affecting the system, do not reverse the polarities.
1) Control panel provides lock control output interfaces. For NO lock ,it is open when power is on, and closed when power is off, so COM and
NO interfaces should be used; For NC lock, it is open when power is off, and closed when power is on, so COM and NC interfaces should be
used.
2) Control panel supports “dry mode” and “wet mode” by setting the jumper, it is “wet mode” when connecting “V+ V-” Input interfaces to
supply power for locks, please shorten 2-3 and 4-5 . Equipment factory default setting is dry mode. For setting “dry mode” and

The background PC software is able to communicate with the system according to two protocols(RS485 and TCP/IP) for data exchange and
remote management. The communication cable should be as far away from high-voltage lines as possible. Do not keep the communication cable
in parallel with power cords or bind them together.
