Wired Module for Tedee Locks GERDA TEDEE-DRY-CONTACT — Dry Contact Interface Module

Wired module for Tedee-compatible smart locks by GERDA provides a dry-contact (potential-free) interface to connect a Tedee lock to external access control systems, alarm panels or home automation controllers. The TEDEE-DRY-CONTACT module is intended for wired integration where a potential-free contact is required to trigger lock actions remotely or to report lock state to third-party equipment. The module supports straightforward connection to controllers that accept dry-contact inputs and helps extend the interoperability of a Tedee lock within existing wired installations.

Advantages

The GERDA wired dry-contact module offers a simple, potential-free interface that avoids voltage conflicts between devices and ensures safe signaling. Its wired design provides reliable connectivity for installations where stable, low-latency control is needed. The module is compact and made to work with Tedee-compatible mechanisms, enabling integration without altering the lock's primary electronics. Installation focuses on terminal connections, allowing integration with alarm systems, access controllers or building automation panels that require a dry contact.

Suitable for

• Integration of Tedee smart locks with access control panels that require potential-free inputs
• Connecting locks to alarm or monitoring systems to report state changes
• Wired home automation setups seeking reliable hardware-triggered lock control
• Commercial or residential projects with existing wired infrastructure

Key specifications

• Interface type: dry-contact (potential-free) relay connection
• Connection: wired terminal block for integration with external controllers
• Compatibility: designed for use with Tedee-compatible GERDA smart locks
• Functionality: remote triggering of lock mechanism and lock state signaling
• Suitable environment: indoor installation within lock or control panel enclosures

How to use

Mount the module according to GERDA installation guidelines and connect the module's terminals to the external controller or alarm input that accepts a potential-free contact. Ensure power to the lock and controller is turned off during wiring. After secure wiring, restore power and verify communication by triggering the contact from the controller and observing the lock response or monitoring the lock state feedback. If required, consult the lock's technical manual to confirm wiring polarity and contact ratings before finalizing the installation.

Usage recommendations

Use the dry-contact module in installations where galvanic isolation between the lock and external systems is required. Verify compatibility with the receiving controller's contact ratings and ensure wiring is performed by a qualified technician to maintain safety and reliable operation.
