Tedee Dry Contact is a matchbox-sized unit that connects to Tedee GO and Tedee PRO smart locks using Bluetooth. It can be wired directly into existing dry contact systems through connections for power and control signals.

WiredSystem opt1

Tedee Dry Contact is designed to expand the functionality of Tedee smart locks by enabling:

  • Direct connections to alarm systems.
  • Local integration with compatible smart home systems.
  • Use with automatic door openers and in critical infrastructure installations.
  • Operation via simple manual controls like buttons and switches.
  • Other functionalities as needed.

Application Example

Suppose you want to unlock a Tedee GO smart lock by pressing a dedicated physical button at the reception desk to allow visitors inside the property without using the Tedee app on a smartphone.

You can connect the Tedee Dry Contact to a battery-powered, compatible wired switch and pair it with the smart lock.

When pressed, this button triggers the Tedee Dry Contact to wirelessly unlock the smart lock via Bluetooth, eliminating the need for apps or an online cloud connection.

Installation Requirements and Safety Considerations

Please read the information below carefully to ensure your safety during the installation process of the Tedee Dry Contact.

The installation of the Tedee Dry Contact is intended for professional setup to ensure safety and compliance with electrical standards.

Tedee Dry Contact must be permanently installed at a location where it can simultaneously connect to the Tedee PRO or the Tedee GO smart locks via Bluetooth, and must be wired to a power source and dry contact controller.


Controlling a Tedee smart lock via Tedee Dry Contact replaces the typical Tedee cloud security system and digital authentication with an alternative, wired access method.

Tedee is not responsible for the physical security of the installation or for protecting your devices against unauthorized access. Like any alarm controller or access management system, its location, administration, and users should be protected, verified, and regularly monitored.

Smart Lock Compatibility

To pair or unpair the Tedee Dry Contact with the Tedee PRO or the Tedee GO, the user must have an owner or administrator access level over the smart lock.

One Tedee Dry Contact controls only one Tedee smart lock.

Bluetooth Considerations

Typically, the Bluetooth range allowing for the operation of a smart lock extends up to 10 meters (approximately 30 feet) around the Tedee PRO / Tedee GO. However, the specific setup and location features may require a closer installation.

Be aware that Bluetooth range is highly susceptible to physical barriers; open spaces allow for a longer connection distance, while walls, doors, or metal structures and installations may significantly reduce this range.

The best method to determine the available location range is to test it by unlocking a smart lock with the Tedee app via Bluetooth at the intended location. If the connection is efficient, that location is suitable for permanent Tedee Dry Contact installation.

Power Supply

Tedee Dry Contact uses a power input of 5-60V DC voltage, offering compatibility with a wide range of power sources from power banks to permanent electrical connections.

Ensure that a power source is available at the intended installation location for the device, where it can connect efficiently to your smart lock via Bluetooth.

Tedee Dry Contact does not include a power adapter.

Never connect Tedee Dry Contact directly to a power outlet or a 230V/110V power supply.


Connect the device only according to the diagram presented in this manual. Improper connections can be dangerous, may damage the device, and could void your warranty.

Danger! Risk of electric shock!

Even when the device is turned off, the outputs may still be live (actively transmitting electricity). All installation work should ALWAYS be performed with the power circuit disconnected.


Connecting the device to a power supply that does not meet the specifications outlined in EN 50081-1, EN 50082-1, UL508, and EN 60950 may void the warranty.


Safety Precautions

Disconnect the installation supply voltage before installing the Tedee Dry Contact device.

Switch off the main fuse or disconnect the power cord from the main socket.

Installation Location

Install the module in a place protected against adverse environmental conditions and unauthorized access, such as in a flush box or inside the enclosure of the controlled device.

Device Placement and Installation

Be aware that metallic elements (wires, housing parts) may negatively influence the wireless connection and operation of the device.

It is recommended to fix the module in a stable position. The device body has two holes suitable for secure installation using screws (not included).

Step 1) Connection Guidelines

The device uses two logical inputs to trigger locking and unlocking operations. These can be wired to any compatible outputs, such as alarm controllers, buttons, switches, or relays.

Two outputs convey the lock’s status, indicating whether it is locked or unlocked and whether the device requires attention, for example, when it is blocked, needs charging, or requires calibration.

The operation of Tedee Dry Contact’s inputs and outputs can be configured within the Tedee app.

Wiring Guide

Consult the diagrams provided below, paying particular attention to the designation of the connectors.
