Left (NC): Normally Close Contact
Center (COM): Common Contact
Right (NO): Normally Open Contact
External active speaker interface: external active
speakers for audio power amplification. One is the audio
signal line, and the other is the ground line (be sure to
ground the line, otherwise there will be noise)
Open the rear case of the device, there is a row of terminal blocks for connecting the power supply,
electric lock control, etc. The connection is as follows:
1) Use built-in screw tool to remove the surface shell;
2) Based installation dimensions, mounting hole in the wall to draw, use an electric drill holes lay;
3) The white rubber plugged into the wall and the bottom fixed with screws to the wall;
4) After connecting the power cord and network cable, screw the surface shell fixed.
