This feature is designed to allow GSC3570 to function like a traditional doorbell, and open the door if wired to an electric lock,
a simple digital upgrade to a traditional (broken) doorbell. If combined with an IP camera, it can help to monitor and update
the home security without paying the subscription fee usually involved for such a service.
The wiring example of GSC3570 as doorbell and open door:
Wiring:
1. A switch (doorbell button) needs to be wired to AIN1 (Blue), AIN2 (Brown) or AIN3 (Grey) and Ground (Black).
2. The label is printed in the back of GSC3570 and a cable with color code is provided with the package. Maximum 3
switch/button can be connected (example: Front Door, Back Door, Garage Door) But ONLY 1 electrical lock or strike can
be controlled (because GSC3570 only has 1 relay control port (COM1, NO1/NC1).
