What is a DPI sensor?

A Door Position Indicator (DPI) is a sensor used to detect the status of a door, whether it is open, closed, or ajar. Door position indicator sensors typically utilize various technologies, including magnetic switches, reed switches, proximity sensors, or mechanical contacts, to detect the position of the door. These sensors can be mounted on the door frame, door leaf, or adjacent surfaces, depending on the specific requirements of the application. 

Product Notes:

• A DPI input is provided for each door in the DC20. Since the DC20 can have up to 4 doors associated, there can be up to 4 DPI sensors connected to an access control controller. 
• Wire type and size: solid or stranded, minimum 24 AWG up to 300 ft.
• Final configuration will be done via the Rhombus console.
• Example use cases for DPI sensors:
  • Used as an added layer of security to trigger alerts when a door is open or closed

Installation Diagrams

DPIs can be installed using either Supervision or No Supervision. 

Supervision

A supervised circuit has additional resistors strategically placed to detect a fault, usually a cut or a short, between the resistor and the DC20. The standard supervised circuit requires 4.7 kΩ resistors. These have been provided with the DC20. 

• Supervision for End of Line resistors.
