Diode

Note

：

1. It is suggested to use a linear power supply unit to prevent reading range reduction at the card reader.

2. It is suggested to use #22~26 AWG insulation wire.

3. Exit button is at N.O. contact.

4. With CE qualified EMC specification.

5. The door strike or relay must have a varistor or a diode across the door strike terminals to suppress

the back EMF of the strike - failure to do so will damage the relay contacts and electronic components,

or even burns the controller.
