3 CHECK POINT DURING INSTALLATION
3.1 REVERSE DIODE CONNECTION
If you connect an inductor (Door Locks or Alarm device) to the output relays, there will be a
high surge voltage created while the inductor is turning on and off. To protect this problem,
connect the reverse diode as the figure below.
1 You need thicker wire if you connect the reader with high current consumption
