• Short press: key time <200mS

Power-on initialization
When the product is powered on, the Blue indicator flashes slowly for 2 times and then stays on, and the initialization is successful.

Pairing
After the product is initialized, short press the pairing button once, the device enters the pairing mode, the distribution Green LED indicator flashes quickly, and exits the distribution network status directly after the timeout, the timeout period is 60S.

Restore factory settings
Press the key for more than 30S, the distribution Green LED flashes 3 times, the device restores the factory settings and enters the pairing state.

Button function

Pairing button:
Short press: when the network is not configured, it enters the network configuration state; when the network is configured, it does not respond.
Press key time 8~15S, clear network information;
Press the key for more than 30S, restore factory settings;
Reset button: restart device.

Power-on default state setting

After the device is powered off, power on again to set the status of the relay after power on. The enumerated values are as follows:
None: Power-off memory, after power-on, the relay keeps the state before power-off.
On: Normally open state; the relay is turned on after power-on again.
Off: Normally closed state, the relay will be disconnected after power-on again.

Remark : After entering the administrator mode, the mobile app can connect to DSW 080 via Bluetooth, and DSW-080 will send the secret key to the mobile app DSW-080 will always be in the broadcasting state when it is not connected. When the user holds the authorized mobile app close to it, it will connect and exchange the secret key.
Whether to open the door automatically depends on the logic of the mobile app.

Garage Door control
DSW-080 can connect to the garage door control board though wire, smart control method can be two option, one is Zigbee for long range control, one is Bluetooth for local control
Option ①:DSW-080 will send the data to Dusun Zigbee gateway though Zigbee and Sync the data to the cloud, user can use the access control app on the mobile phone to control the garage door open.

Remark : After entering the administrator mode, the mobile app can connect to DSW-080 via Bluetooth, and DSW-080 will send the secret key to the mobile app
DSW-080 will always be in the broadcasting state when it is not connected. When the user holds the authorized mobile app close to it, it will connect and exchange the secret key.
Whether to open the door automatically depends on the logic of the mobile app.

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.
  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.

Door access control

DSW-080 can connect to the door button via wire. Mobile phone with app can scan the Bluetooth signal in the near, the DSW-080 is always in activity status, the app will be automatic connect the DSW-080,User can control the door by the mobile phone
Remark : After entering the administrator mode, the mobile app can connect to DSW 080 via Bluetooth, and DSW-080 will send the secret key to the mobile app DSW-080 will always be in the broadcasting state when it is not connected. When the user holds the authorized mobile app close to it, it will connect and exchange the secret key.
Whether to open the door automatically depends on the logic of the mobile app.
