7.2.4 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. If you do not connect a
reverse diode, the surge voltage will transfer and damage the electronic circuit of the controller.
It is strongly recommended to add a reverse diode between the inductor coils to absorb this
surge voltage.
