About the DR40

The DR40 is Rhombus' newest three-in-one combination of a reader, camera, and audio device. This powerful device allows you to enter doors by simply waving your hand in front of the reader. It verifies your identity by communicating with your phone via Bluetooth/NFC. You also have the option to use encrypted key cards. It can also be used as a standalone intercom to communicate with guests or delivery drivers.

Installation

• Communication: the DR40 communicates with the DC20 over RS-485 using OSDP.
• 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 PoE switch or through a PoE injector and connect it via Wi-Fi.
• 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.
