Whether to open the door automatically depends on the logic of the mobile app.
11.3 Intercom control
Can connect the phone to DSW-080 through a flat cable, and then connect DSW-080 to the network to
realize remote control of the phone and remote real-time access to the status of the call.
DSW-080 can be set as a Zigbee router, some Zigbee sensor and devices can connect to it.
Remark:
GND and SENSOR is for detect the action of bell ring , NO and COM is used for open the door. NC
normal not to be used
VCC can connect to the power supply of the intercom, in common , the voltage will be from 5VDC to
12VDC
The circuits and interfaces of different brands of intercom are different, so needed to confirm which ports
are connected correctly.
Step 1:Find the GND port
Connect the multimeter and activate the mode to measure DC voltage.

Hangzhou Roombanker Technology Co., Ltd. A DUSUN company

Tel:[phone] 8810480 Hangzhou 310004, china
Website: www.dusuniot.com www.dusunremotes.com www.dusunlock.com
Connect the black wire to the COM terminal of the multimeter and the red wire to the V,Ω,mA.
Test all possible combinations between the terminals of the intercom strip until the multimeter shows
the highest positive voltage.
If the voltage is negative, invert the connection of the cables: connect the red where the black and the
black where the red.
Connect the DSW-080 GND output to the terminal where the black cable of the multimeter is
connected.
Remark :If there is a corresponding logo on the intercom circuit board, generally GND or Common
Ground represents GND
Step 2:Find the Sensor port
Measure DC voltage mode on the multimeter and connect the black wire to GND terminal.
Connect the red lead from the multimeter to each of the terminals on the intercom. It will show constant
tension. If, when the doorbell button is pressed, the voltage differential varies markedly, that is the sensor
terminal.
Step 3:Find the COM and NO port
Generally, NO and COM are the two ends of the door open button.
Use the beep of the multimeter to find the terminal that is completely short-circuited to the two ends of
the door open button. These two terminal can be used to connect the NO and COM ports of DSW-080.
Remark : If cannot find a terminal that is completely short-circuited to the two ends of the door open
button, you can directly connect COM and NO to both ends of the door open button. But in this case you need
a soldering iron tool to achieve
If the intercom door open button is a touch type button, you can choose an electric accessory to connect
to the J3 interface of DSW-080. This accessory will be described in detail in the instructions for use.
⚫Call function connection (traditional intercom)
Traditional intercom are generally analog microphones. Connect the intercom as shown below:
1. Unplug the microphone, then connect the intercom main body and micphone to smart switch
respectively.
In this way, smart switch can receive and transmit call audio data from the RJ9 interface, and then use
Bluetooth to communicate with the gateway to achieve remote calls.

⚫Call function connection (Digital intercom)
For digital phones, we need to use an accessory (sound pickups), the pickups has a noise reduction
microphone and speaker function, supports USB audio protocol, the connection diagram is as follows,
1. Connect the output port -Type C of the sound pickups to the power supply port of the smart switch
2. Connect the power supply port-USB of the pickup to the 5VDC adapter for the power supply of the
pickup and smart switch.
Note: Install the sound pickups as close to the intercom as possible.
Similarly, the smart switch get the audio data of the call from the USB port, and communicates the data
with the gateway via Bluetooth to achieve the remote call function.
