Power Transfer Devices

Power transfer devices are essential components in modern door hardware systems, enabling the safe and concealed passage of electrical wiring from the door frame to the door leaf. These devices are critical for supplying power and signal transmission to door-mounted hardware such as electric locks, access control readers, exit devices, sensors, and monitoring systems. John Barnes Group supplies high-quality power transfer devices from leading brands Dormakaba and Lockwood—both known for reliability, durability, and compliance with Australian Standards.

Power transfer devices are a must-have for any installation where concealed, protected wiring is essential for both function and appearance. They are commonly specified in commercial, institutional, healthcare, and high-security environments. Buy Power Transfer Devices online today from the John Barnes online shop!

 

What Are Power Transfer Devices?

A power transfer device provides a secure, hidden pathway for electrical cabling between the fixed door frame and the moving door leaf. This prevents exposed wiring, which could be vulnerable to wear, tampering, or damage from door movement. Power transfer devices are engineered to maintain door functionality and appearance while meeting electrical safety and fire compliance requirements.

 

Types of Power Transfer Devices

Buy Concealed Power Transfer Devices online

Installed within the door and frame, concealed units provide a completely hidden cable pathway, protecting wiring and maintaining clean aesthetics.

Use cases:

  • High-end architectural projects

  • Commercial offices

  • Healthcare facilities

Buy Surface-Mounted Power Transfer Devices online

Mounted on the surface of the door and frame, these devices offer easier installation and retrofitting while still protecting the cable within a flexible conduit or armoured housing.

Use cases:

  • Retrofit projects

  • Institutional buildings

  • Utility and service areas

Buy Armoured Power Transfer Cables online

Flexible, stainless steel armoured cable solutions for high-security environments where cable protection is paramount.

Use cases:

  • Correctional facilities

  • Banks and secure facilities

  • Military installations

 

Key Features and Specifications

  • Cable Protection: Prevents wear and damage during door operation

  • Mounting Options: Concealed or surface-mounted

  • Cable Types: Supports multiple wires for power and data transmission

  • Materials: Stainless steel, anodised aluminium, or heavy-duty polymer housings

  • Fire Rating: Compatible with fire-rated door assemblies where required

  • AS1428.1: Ensuring devices do not obstruct accessible door operation

 

Material and Durability Considerations

Stainless Steel Housings

Provide exceptional strength, security, and corrosion resistance—ideal for high-traffic or high-security installations.

Anodised Aluminium

Lightweight yet strong, aluminium housings offer an attractive finish for architectural projects.

Heavy-Duty Polymer

Used in certain surface-mounted models for cost-effective, impact-resistant performance.

 

Applications: Residential vs Commercial

Residential Applications

Although less common in standalone homes, power transfer devices are used in high-end residential projects with electronic locks, access control, or home automation systems:

  • Luxury homes with keyless entry systems

  • Apartments with integrated intercom and access control

Commercial Applications

Power transfer devices are essential in many commercial and institutional environments:

  • Offices with access control and monitoring systems

  • Hospitals requiring powered locking and monitoring on patient room doors

  • Education facilities with electronic security

  • Government and defence buildings

 

Product Selection Guidance

For Architects and Designers

  • Choose concealed models for aesthetic projects

  • Ensure capacity for required number of conductors and cable gauge

  • Specify finish to match surrounding hardware

For Builders and Installers

  • Verify compatibility with door/frame type and fire rating requirements

  • Ensure correct alignment and mounting for smooth door operation

  • Select flexible cable designs for heavy or high-cycle doors

For Facility Managers

  • Choose heavy-duty or armoured models in high-traffic or security-sensitive areas

  • Schedule routine inspections for wear or cable fatigue

  • Keep spares for quick replacement in case of damage

 

Installation Tips

  • Follow manufacturer templates and instructions for drilling and routing

  • Protect cable ends during installation to prevent damage

  • Test full door swing to ensure no binding or cable strain

  • Integrate with access control wiring neatly for serviceability

 

Maintenance and Care
