Electric Conductor Hinges, or power transfer hinges as they are sometimes known, offer a totally discreet way of transferring power from the frame to the door. This is extremely beneficial in access control systems and in high security environments, such as detention centres or prisons.

Cooke Brothers have the ability to supply up to 12 wire conductor hinges across many of our flagship ranges including the Slimline, Loadmaster and Concealed Bearing Ranges.

All hinges are fully tested to ensure power continuity before despatch. Please note that these hinges are not suitable for load-bearing, so doors must be fitted with the appropriate matching non-conductor hinges.

Please contact our technical sales department to discuss your requirements further.

Electrical Conductor Hinges

Cooke Brothers offers a full range of hinges suitable for use on smoke and fire door assemblies, tested from between ½ hour to up to 4 hours, you can be confident in our products to meet your requirements.

To further demonstrate our products suitability, Cooke Brothers have had their flagship ranges of hinges tested and approved at Warrington Fire Research. Copies of Certifire certificates are available throughout this website.

Fire Door Packs
Fire door packs are available consisting of three hinges and fully prepared intumescent pads. Please contact our technical sales department for further information.


Compliance Testing
Crucial to the success of the Cooke Brothers range of Architectural Hinges, is our continual development and testing program. All hinges are rigorously tested before product launch, both internally and externally to ensure they meet the required standard. We also have an ongoing program of product testing on our CE range of hinges to ensure they continue to be certified.

BS EN 1935:2002
The Current standard for Singles Axis Hinges is BS EN1935:2002. Hinges are tested against a standard door and specific number of cycles in order to achieve certification. A single hinge is tested, whereas in reality a minimum of three hinges will support the door.

CE Certification
Hinges that are used on Fire and Escape Routes must legally be CE marked. The mark on the product will satisfy building inspectors and trading standards officers that you have done your best to ensure that the building is safe to use. Increasingly, it will become the duty of the building owner to ensure that the building is safe to use and this is where CE marked products will help.

CE marking is not easily achieved, products have to be independently tested at both initial product launch and annually throughout the life of the product. To keep your buildings safe, only use products with this mark and ask for evidence of Certification. Copies of our Certification are available to download on the individual product pages.

In addition to the product testing to BSEN1935, products are also fire tested to EN1634 and are manufactured in a factory with a recognised FPC - Factory Production Control. This ensures that the processes and procedures used to manufacture the products are controlled within an Audited Quality System. Cooke Brothers have the Quality Management System ISO 9001 in place and are regularly audited to ensure we comply with this standard.

Certifire is the product certification division of Warrington Fire Research, they safety test a huge range of hardware products. Certifire approved products will all work together on the doorset assembly to ensure absolute safety against the spread of fire. CE marked products do not have the same rigorous certification requirements as Certifire approved products, so to remove any doubt, always ensure you specify a Certifire approved product for use on Fire and Escape Door Assemblies. Copies of our Certifire Certificates are also available for download within this website.

Disability Discriminations Act
Part III of the Disability Discriminations Act 1995 (DDA) places duties on those providing goods, facilities or services to the public. Since October 2004 all 'service providers' have been required to take reasonable steps to provide for the needs of disabled people who wish to the use their services. This includes the removal of the Physical Barrier.

Cooke Brothers are equally concerned about how our products affect the day to day lives of people with disabilities. Fire regulations demand that all fire and escape doors will close upon the event of a fire and though they continue to take precedence over the requirements of DDA, this can cause a conflict. One way to ensure that doors open easily for wheelchair users and close easily on the event of a fire is to use hinges with the lowest possible opening and closing torque resistance. BSEN1935:2002 allows a maximum of 4Nm resistance to opening, whereas the high quality bearings used in Phoenix Architectural Hinges will typically operate at less than 1Nm.

Compliance Testing

As part of BS EN 1935:2002 there are currently 14 Grades which are tested, this covers hinges for both windows and doors. The weights currently tested range from 10Kg right through to 160Kg, with up to a maximum of 200,000 test cycles.

The table below details the current test requirements.

Hinge Grade Usage Test Cycles Door Mass
1 Window 10,000 10 kg
2 Window 10,000 20 kg
3 Window / Door 25,000 20 kg
4 Door 200,000 20 kg
5 Window 10,000 40 kg
6 Window / Door 25,000 40 kg
7 Door 200,000 40 kg
8 Window 10,000 60 kg
9 Window / Door 25,000 60 kg
10 Door 200,000 60 kg
11 Door 200,000 80 kg
12 Door 200,000 100 kg
13 Door 200,000 120 kg
14 Door 200,000 200 kg


Please Note: BS EN1935:2002 is likely, over the next two years, to be updated to include testing for door test masses of 200Kg and over 250Kg. This will also for the first time include continuous hinges, which are increasingly being specified on Security Door applications.

Cooke Brothers are currently developing additional ranges to meet these new standards and testing our range of security continuous hinges to ensure they comply with the latest legislation.

Corrosion Resistance
Cooke Brothers conduct tests on all hinge ranges to determine their level of corrosion resistance and allow the hinge specifier to choose hinges with durability and longevity. Our tests are conducted to the British Standard BSEN 1670 (1998), in a temperature and humidity controlled enclosure.

Hinges are subjected to salt spray tests within the controlled environment to simulate an artificial atmosphere. Products are placed in the cabinet for a specific time period where a fine mist of salt water is allowed to 'attack' the products and identify the level of corrosion resistance that ether the base metal can stand. They are then categorised into five grades of corrosion resistance, depending on how long they are able to withstand the testing procedure, these grades are detailed below:

  • Grade 0 - No defined corrosion resistance
  • Grade 1 - Low corrosion resistance (24 hours of salt spray testing)
  • Grade 2 - Moderate corrosion resistance (48 hours of salt spray testing)
  • Grade 3 - High corrosion resistance (96 hours of salt spray testing)
  • Grade 4 - Very high corrosion resistance (240 hours of salt spray testing)
  • Grade 5 - Exceptionally high corrosion resistance (480 hours of salt spray testing)

A part of the testing procedure required for a hinge to be CE marked also determines its level of corrosion resistance.

Selecting the Correct Base Material
Phoenix architectural hinges are available in a choice of four base metals, you should consider the level of corrosion resistance required for the hinge application when choosing the base metal for your hinges. It is the base metal which determines corrosion resistance, not the applied finish. Mild steel is not considered to be corrosion resistant at all, even with applied finishes, you should only site hinges made of mild steel indoors.

The most corrosion resistant base metals available are the stainless steel hinges. Available in a choice of two types of stainless steel, Phoenix stainless steel hinges are thoroughly tested and guaranteed to be corrosion resistant. Stainless steel grade 304 is the most commonly used grade of stainless steel, it is suitable for use in most internal and external environments. Stainless steel grade 316 is a marine grade stainless steel, recommended for all high corrosion environments, including use in coastal regions and high humidity areas (swimming baths, etc).

In addition to the above testing for BSEN 1670 grades 0 to 5, we have also tested the stainless steel versions of the seven hinges range of products to 1000 hours of salt spray testing. As you can see from the grading table above, this is exceptionally high corrosion resistance, far exceeding the requirements to be categorised as grade 5.

The Standard for Single Axis Hinges, BS EN 1935:2002, provides details on product types, classification by use, test cycles, door mass, corrosion resistance, as well as definitions, product performance requirements, test apparatus, test methods and marking of products. In addition, the standard also includes details for people with special needs.

The scope of the standard specifies requirements for single-axis hinges, for windows and doors opening only in one direction, whose rotation axis is no more than 30mm away from the sash or door. It also covers for both fixed pin and lift-off hinges.

The European standard classifies single-axis hinges using an 8 digit coding system. This is also in line with standards for most other items of building or architectural hardware.

8 Digit Classification
To Further Explain the 8 Digit classification, Cooke Brothers have introduced graphical symbols, these have kindly been reproduced from the ABHM (Association of Building Hardware Manufacturers).

Installation Information

On standard doorsets it is usually recommended to use three hinges, the top and bottom hinges being fitted approximately 250mm from the door end to the hinge centre line, with the third hinge being fitted in the centre of the other two. Equally spaced hinges will minimise warping with extremes of temperature or humidity.

The drawing shows both standard and special fitting arrangements for hinges.

Figure 1 shows a standard hinge arrangements.

Figures 2, 3 and 4 detail hinge positions for doors, where the hinges are operating at the near the maximum load capacity, or where door closers (particularly back-check closers) are in use and the door is in a high frequency of use environment.

On doors in excess of 2100mm high it is recommended that a fourth hinge is fitted, the fourth hinge should be fitted about 200mm below the top hinge.

Door Weights
The chart below details the mass ranges of typical doors. It is vital to have an accurate measurement of the weight of the door before selecting the correct hinge to use.

Mass ranges of typical doors Size (mm) Mass (kg)
Cupboard, wardrobe, cabinet louvred doors and shutters 2040 x 626 x 40 3 to 10
Light internal large wardrobe and large louvred doors 2040 x 926 x 40 10 to 17.5
Medium internal doors 2040 x 1012 x 40 17.5 to 25
Heavy internal doors 2040 x 1012 x 40 25 to 37.5
Half hour fire doors 2040 x 826 x 40 25 to 37.4
Light external doors 2040 x 907 x 40 20 to 37.5
Heavy external doors 2040 x 1002 x 44 37.5 to 55
One hour fire doors 2040 x 826 x 54 37.5 to 72.5
Oversize or special external doors 2400 x 1200 55 to 110

The weight of standard Architectural Ironmongery is often not added to the total weight of the doorset, however again it is important that this is taken into consideration. The chart below highlights typical weights of Ironmongery.

Typical weight of ironmongery (kgs) General Aluminium Stainless
Pair of lever handles 0.7 0.4 1
Kickplate 900 x 200 x 1.5 (pair) 3 1.5 4
Heavy duty door closer 3 x x
Economy door closer 2 x x
Euro pattern lock 72mm ctrs 1 x x
English pattern lock 57mm ctrs 0.5 x x

Adjusted Door weights
The reliability of the hinges depends on several factors. Door widths and the type of door closer specified can have an important bearing on the weight of the door.
If fitting a standard door closer add 20% to the weight of the door.
If fitting a back-check door closer then add 75% to the weight of the door.
For doors of excessive widths (1000mm or more) further adjustment needs to be made to allow for the increased bending movement acting on the hinges.
The following chart illustrates the effective increase in door mass as the width of the door increases.

Door width (mm) Theoretical increase in door mass %
1000 0
1050 10
1100 18
1150 26
1200 33
