About the DR40

The DR40 is Rhombus' five-in-one device combining a reader, camera, button, audio device, and relay. The relay can be used with a Doorbell Rule. This powerful device allows you to enter secured locations via mobile app credentials (NFC), wave to unlock (BLE), or physical key cards.

The device contains a camera that allows you to view footage via the Rhombus Console, and can also be used as an intercom to communicate with guests or delivery drivers.

As a standalone device, the camera, intercom system, and button (doorbell) can be used without needing to connect to a DC20 for badge reader functionality. 

Installation

• Communication: the DR40 communicates with an Access Controller (DC20) over RS-485 and uses the OSDP Protocol. It will be wired into the RS-485 ports on the DC20.
• Power (V+/V-): solid or stranded, minimum 18 AWG, 300 ft max run.
  • If PoE is used to power the DR40, V+/V- won't be used. To connect the DR40 to your network, you can run Cat5/6 directly to a 802.3af compliant switch or through a PoE injector and connect it via Wi-Fi.
  • Power to the reader can be supplied using PoE or a 12-28VDC external power source. DR40 has a maximum current rating of 791 mA at 12VDC and cannot be powered directly by the DC20.

Figure 1.) Example wiring diagram for the DR40 showing all available wires.

Wiring Requirements and Diagrams

• Data (A/B/GND): solid or stranded, twisted pair, minimum 24 AWG, 300 ft max run.
• Other: (COM/NO): solid or stranded, minimum 24 AWG, 300 ft max run.
• Note: Existing cables can potentially be re-used if they meet the minimum required AWG. Wiring methods used shall be in accordance with the National Electric Code, ANSI/NFPA 70. 

For more details, reference our DR40 manual.

• Connect the [A], [B] and [GND] lines of the DR40 to the corresponding terminals in the DC20.
• Note: We recommend consulting the appropriate federal, state, and local authorities for any relevant regulations at the time of installation.

Figure 3.) Power to the DR40 can be supplied via PoE. If PoE is not used, an Ethernet connection is still required.

Figure 4.) Power can also be supplied using a 12-28VDC external power source. An ethernet connection is required. 

Figure 5.) The DR40 also comes equipped with one dry contact normally open relay. This can be used for externally powered devices rated up to 30VDC/DC, 1A max.

Registration

The DR40 can be combined with the DC20 or as a standalone product. Depending on the use case, two different registration methods are available.

With the DC20

The DR40 will auto-register to your Rhombus Console once it's connected to a DC20, assuming that the DC20 has a stable network connection.

To ensure this happens, navigate to the "Settings" tab, select "Door Controllers," and click the controller you wish to verify. Ensure "Auto-register Readers" is toggled on in the RS-485 Ports section (this is enabled by default).

For Standalone Use

Once the DR40 has been installed, it can be registered through the Rhombus mobile app via Bluetooth or via QR Code.

Bluetooth Registration

1. In the Rhombus App, tap "Menu," then "Register Devices."

2. Tap "Register via Bluetooth."

3. Tap the location where you'd like the device registered. If the location hasn't yet been created, you can tap "Add New Location."

4. Tap the toggle beside the DR40 you are trying to register. Tap "Next."

5. Ensure "Ethernet" is selected for the internet connection type, and tap "Next."

7. The following screen is the final step in the registration process.

QR Code Registration

1. In the Rhombus App, tap "Menu," then "Register Devices."

2. Tap "Register via QR Code."

3. Tap the location where you'd like the device registered. If the location hasn't yet been created, you can tap "Add New Location."

4. Ensure "Ethernet" is selected for the internet connection type, and tap "Next."

5. Aim the QR code displayed on the app at the camera lens on the DR40. When the DR40 clicks, it will register. Tap "Done" when finished.

Audio Enablement

To utilize audio features on the DR40, specific permissions to allow listening and recording must be enabled for your organization and the individual device.

1. Log in to the Rhombus Console, navigate to "Settings," and click "Account."

2. Scroll down, and turn on the toggle for "Allow Audio Listening & Recording."

3. Navigate to the DR40 you wish to enable audio features on.

4. Click the "Audio Controls" button, and toggle on the "Listen through video intercom" or "Speak through video intercom" settings as desired.

Setting Up Doorbell Notifications

Our doorbell sound is intentionally designed to be attention-grabbing without being disruptive. It serves to alert nearby individuals promptly, even if they're not actively monitoring the device.

Note: The doorbell volume is set to the maximum allowable level by default and further adjustments are not possible.

To increase doorbell volume:

• Connect the device that is monitoring for notifications (an iPad etc.) to an external speaker to boost the sound of the notification.

Note: When using an iPad or other device, the sound associated with a doorbell notification will only play if you are actively watching the specific door whose bell is rung.

• You can connect the DR40 Door Reader to a doorbell chime to boost the volume on the doorbell press. For more information, see our article on Connecting a DR40 to a Wired Doorbell.

Doorbell events can be set up in two ways:

• A Doorbell Rule can be created on the DR40 devices page, and then configured in User Notifications.
• A policy with "Doorbell Press" as part of the policy can be assigned and configured in User Notifications.
  • For more information on creating policies, see our article on Creating and Assigning Alert Policies.

Creating a Doorbell Rule

A Doorbell Rule can provide several actions on button press:

• Generate Notification​
  • Generates an instant notification that will not be associated with any clips to reduce delivery time. Notifications for these can be configured under the "Manage Notifications" section in settings by selecting the Video Intercom/Badge Reader dropdown, and clicking "Doorbell Pressed."
• Play Audio File​
  • Play a previously saved clip, upload text-to-speech, create a new recording, or upload a recording. Audio files can be played through a connected A100 or the DR40.
• Trigger Relay
  • The DR40 can be directly connected to a simple relay on the device. Its hardware includes a button configured as a doorbell and a generic relay.
  • The DR40 is equipped with one dry contact Normally Open (NO) relay that can control externally powered devices such as door chimes or lights rated up to 30 VAC/DC, 1A max.
• Call Phone
  • The DR40 will start a two-way call with the designated phone number. If answered, an automated message will play stating someone is at the door, then the call will be connected with the DR40. During the phone call, if "9" is pressed, the relay connected to this DR40 will unlock, allowing the person at the door to enter.

Note: If using the "Call Phone" button press action, the incoming call will be from (888)779-1201. We recommend adding this phone number to your contacts to prevent the call from being missed or considered spam.

1. Navigate to the "Devices" page, select the "Video Intercoms" tab, and click the name of the DR40 for which you wish to create a rule.

2. Scroll down, in the "Settings and Details" section, click "Edit."

3. An "Add Rule" button will appear. Click this to set a schedule for the rule and configure the type of rule that will be used. Multiple rules can be configured.

4. Select or create a schedule, then select the action you want to generate. If you want to add more than one action for the Doorbell Press, click "Add Another Action." When finished, click "Save."

5. Once one rule has been saved, you can add additional rules by selecting "Add Another Rule."

Deleting a Doorbell Rule

1. Once a Doorbell Rule has been created, it can be deleted by clicking the trash can icon and confirming the deletion.

NFC Antenna

When using a key card with the DR40, hold the card over the NFC antenna, as shown below, to ensure the credential is read properly.
