BYPASS DIODE CONNECTION
If you connected an inductor (door locks or alarm device) to the output relay, there should occur a voltage surge while the inductor is turning on and off. If you do not connect a reverse diode to the relay, the surge voltage will cause damage to the electric circuit of the controller. To reduce this surge, it is recommended to connect a reverse diode between the devices.
