# Integration Between S532 and Akuvox Answering Units

The door phone S532 can be connected to Akuvox answering units through the Akuvox analog switch, achieving easy calling and unlocking.

With the answering units, users can:

- answer calls from S532;
- open the door for visitors during a call by pressing the button on the unit.

## Topology

- Direct Mode: The S532 is connected to the analog switch through wires.
- Proxy Mode: The S532 is NOT connected to the analog switch, but it can make calls to the answering units through the configuration on its web.

## Wirings

Wirings vary by the analog switch used.

- [Connect the answering units to AS11](/v1/docs/integration-between-s532-and-akuvox-answering-units#connect-answering-unit-to-as11).
- [Connect the answering units to AS12](/v1/docs/integration-between-s532-and-akuvox-answering-units#connect-answering-units-to-as12).

> [!NOTE]
> Note
> 
> The connection between the analog switch and the answering unit. This determines the **analog number**. This number is the basis for users to call the answering unit on the S532.

## Connect Answering Unit to AS11

### Connection between S532 and the AS11

Please note that using SEL1 and SEL0 for connection is different. Connecting SEL0 to SEL means the analog number generated by the analog switch is from 0 to 99, while connecting SEL1 to SEL is 100 to 199.

![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/Connection between S532 and the Analog Switch.png)

### Connection between the AS11 and the Answering Unit

The answering unit has each red(positive) and black(negative) wire.

The red wire is connected to DX, and the black one is connected to EX, generating the analog number XX or 1XX.

For example, in this demonstration diagram, the answering unit is connected to D0 and E2.

Therefore, when S532’s SEL0 is connected to the analog switch’s SEL, the analog number is 02. When S532’s SEL1 is connected to SEL, the analog number is 102.

## Connect Answering Units to AS12

Watch: [[Video]Akuvox Analog Switch and Answering Unit Wiring Tutorial](https://knowledge.akuvox.com/docs/videoakuvox-analog-switch-and-answering-unit-wiring-tutorial)

- One AS12 can be connected to 4 answering units.
- The S532 should be connected to a 12V 3A power adapter so that it can power the analog switch and handset.
- The blue, black, yellow, and red wire of the analog switch is connected to the S532’s EK, 12V power-in or NC1, GND, and Line ports, respectively. If NC1 is used, S532 will use Relay A for power output; you need to turn on the [12V power output feature](/v1/docs/integration-between-s532-and-akuvox-answering-units#12v-power-output-setup) on the S532’s web interface and use Relay B for door opening when adding a user.

- The answering unit is connected to the **FX** interface. For example, if the unit is installed on the fourth floor and it is connected to F1. The analog number will be 401. F1-F4 corresponds to 01-04.
- The jumper 0-5 short circuit defines the floor number. Please refer to the chart below.

★ indicates short circuit. For example, if jumper 4 is short-circuited, the unit is on the second floor. Then, the analog numbers will be 201, 202, 203, and 204.

## On-Premise Configuration

After the correct connection, set up the feature on the S532’s web interface. Select the right analog integration brand and assign the analog number to specific users.

### Call Setup

Users can enter the analog number or the replaced number on S532(Both in Direct and Proxy modes) to call answering units.

#### Set the S532 in Direct Mode

1. Use the device IP to log into its web interface. The default username and password are admin.
2. Go to **Intercom > Basic** and select **Akuvox** as the Adapter brand.

![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-8KYPZ3XX.png)

1. Go to the **Directory > User** interface and click **Add** to add a user.
2. After setting the username and ID, scroll to the **Contact Details** section and set it as instructed.

1. Click Submit to save the settings.

#### Set the S532 in Proxy Mode

1. Use the device IP to log into its web interface. The default username and password are admin.
2. Go to **Intercom > Basic** and select **Akuvox** as the Adapter brand.

1. Click Submit to save the settings.

### Door-opening Setup

Residents can press the button on the answering unit to open doors during a call with the S532 in Direct mode. This does not require extra configuration.

The door opening between S532 in Proxy mode and the answering unit can be achieved by DTMF codes. The S532(Direct) can send DTMF signals to the S532(Proxy).

1. Go to **Intercom > Basic > Analog Setting** on the S532(Direct)’s web interface.
2. Select **Akuvox** as the Adapter and set the **DTMF Send code**. If there are multiple doors, just enter the code in series. For example, “0123”.

![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-QWPRIA1H.png)

1. Go to **Access Control > Relay** on the S532(Proxy)’s web interface. Set the DTMF code. The code should be consistent with or contained in the DTMF Send code.

![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-4M7OF8AP.png)

1. Click Submit to save the settings.

### 12V Power Output Setup

If you use [NC1 to connect the analog switch AS12](/v1/docs/integration-between-s532-and-akuvox-answering-units#connect-answering-units-to-as12), you need to set up the 12V power output feature on the web interface.

If not, simply skip this part.

1. Go to the **Access Control > Relay > 12V Power Output** interface.
2. Set **12V Power Output** to **Always**.
