Yes, an electric fire door can meet EI fire resistance requirements. The key condition is that the electric operator, hold-open mechanism, and all associated components must be part of a tested and certified assembly. The fire resistance classification applies to the door as a complete system, not to the leaf alone. The sections below address the most important technical and specification questions architects face when working with electrified fire doors.
What happens to fire resistance when a door is electrified?
Adding an electric operator, magnetic hold-open device, or automated closing mechanism to a fire door does not automatically compromise its fire resistance. However, it does change the scope of what must be tested and certified. The fire resistance classification is only valid when every component integrated into the door assembly has been included in the type test. Any modification that falls outside the tested configuration invalidates the classification.
This is a critical point for architects specifying fire doors in production halls, logistics centres, or healthcare complexes where automated operation is operationally necessary. The question is not whether a door can be electrified, but whether the specific combination of door leaf, frame, operator, and closing mechanism has been tested as a unit under EN 1634-1 and classified accordingly under EN 13501-2.
In practice, this means that sourcing a fire door leaf and an electric operator from two separate suppliers and combining them on site creates an untested assembly. The resulting installation may not carry a valid classification, which creates a compliance gap that will surface during a fire safety review or building inspection. Architects working on permit-ready designs need to verify upfront that the electrified configuration is covered by the manufacturer’s classification report, not just the door leaf in its manual form.
Manufacturers who have invested in testing complete electrified assemblies will be able to provide classification reports that explicitly reference the operator type, the hold-open device, and the release mechanism. If a supplier cannot produce this documentation, the assembly is not demonstrably compliant. Metacon-Next’s fire-rated industrial doors are tested as complete systems, covering the configurations relevant to industrial applications.
What is the difference between EI1 and EI2 for electric fire doors?
EI1 and EI2 are both fire resistance classifications under EN 13501-2 that combine integrity (E) and insulation (I), but they differ in how strictly the insulation criterion is applied. EI2 permits a higher temperature rise on the unexposed side of the door — specifically, a mean rise not exceeding 140 K and a maximum rise not exceeding 180 K at any single point. EI1 applies a stricter insulation criterion, limiting the temperature rise on the unexposed side to a lower threshold than EI2 allows.
For architects, the practical implication is that EI1 and EI2 are not interchangeable in a specification. Substituting one for the other without a project-specific fire safety calculation is not acceptable. The required classification depends on what is on both sides of the door opening: the occupancy, the evacuation route, the fire load, and the compartment design. A fire safety engineer or fire safety calculation determines which criterion applies to a given opening.
Electric fire doors are available in both EI1 and EI2 configurations, but the tested assembly must match the specified classification exactly. A door tested to EI1 60 satisfies a requirement for EI2 60 because it meets the stricter insulation criterion. The reverse is not true. When specifying an electric fire door, architects should confirm which classification the tested assembly carries and ensure it corresponds to or exceeds the project requirement. Always specify EI1 or EI2 explicitly — never refer to “EI” alone without the suffix, as the two criteria have meaningfully different performance thresholds.
How does an electric fire door get its EI1 or EI2 classification?
An electric fire door earns its EI1 or EI2 classification through a standardised fire resistance test conducted under EN 1634-1 by an accredited testing body. The door assembly — including the leaf, frame, seals, hardware, and any integrated electric components — is exposed to a defined temperature-time curve in a furnace. The assembly passes if it maintains integrity (no flame or hot gas penetration) and insulation (temperature limits on the unexposed side, per the applicable EI1 or EI2 criterion) for the required duration. Results are then classified per EN 13501-2.
The test result is documented in a classification report, which specifies the exact configuration that was tested. This report forms the basis for the CE declaration of performance. For an electric fire door, the classification report must explicitly cover the operator type, the power supply and fail-safe mechanism, and the release trigger. If the tested configuration used a specific electromagnetic hold-open device, that device must be present in the installed assembly for the classification to remain valid.
After testing, the manufacturer applies the CE marking and makes the declaration of performance available. For industrial fire doors, CE marking is governed by two standards simultaneously: EN 16034, which covers fire- and smoke-resisting closing elements, and EN 13241, which applies to industrial doors generally. Both apply at the same time and are not interchangeable. Architects and building inspectors can verify compliance by cross-referencing the installed product against the classification report. This is why complete documentation at the specification stage matters: a classification report that only covers the manual version of a door does not validate an electrified installation, even if the door leaf is identical.
Metacon-Next products are tested by Efectis, an accredited European testing body, and all classification reports are publicly available. This level of documentation transparency allows architects to verify compliance without requesting documentation through a sales contact.
What are the main types of electric operators used on fire doors?
The three main types of electric operators used on fire doors are electromagnetic hold-open devices, electromechanical door closers, and automated opening and closing drives. Each operates differently in relation to fire safety, and each must be covered by the tested assembly configuration to contribute to a valid EI1 or EI2 classification.
Electromagnetic hold-open devices
These devices hold the door in an open position using a magnetic connection to a wall or floor plate. When the fire detection system triggers, the power supply is cut and the door closer releases the leaf, which then closes under spring tension. This is a fail-safe configuration: power loss equals door closure. Electromagnetic hold-open is common in production environments and logistics centres where doors must remain open during normal operations but close automatically on alarm. The device must be listed in the classification report for the hold-open configuration to be valid.
Electromechanical door closers and automated drives
Electromechanical closers integrate the closing force within a powered unit and can be programmed to close at a defined speed or in response to a signal. Automated drives, by contrast, actively open and close the door on demand and are often used where forklift or pedestrian traffic requires frequent, controlled passage. For fire doors, automated drives must incorporate a fail-safe closure mechanism that operates independently of the drive motor in the event of power failure or fire alarm activation. The tested assembly must demonstrate that this mechanism functions reliably within the fire resistance duration. Not all automated drive systems have been tested in combination with fire-rated door assemblies, which is why verifying the classification report is essential before specifying this configuration.
Which technical documents should architects request for an electric fire door?
For an electric fire door, architects should request six categories of documentation: the classification report, the CE declaration of performance, the installation and maintenance manual, the wiring and integration specification for the electric components, the EPD if required for sustainability assessment, and any country-specific test extensions where the project is located outside the Netherlands.
- Classification report: The primary compliance document. It must explicitly cover the electrified configuration, including the operator type and fail-safe mechanism, and must state the EI1 or EI2 classification with the tested duration. If it only covers the manual version, it does not validate the electric installation.
- CE declaration of performance: Confirms the product meets the requirements of the Construction Products Regulation (CPR) and references the classification report. For industrial fire doors, this covers both EN 16034 (fire- and smoke-resisting closing element) and EN 13241 (industrial door). Both are required simultaneously and are not interchangeable.
- Installation and maintenance manual: Specifies how the door must be installed and what maintenance intervals apply to maintain the classification. For electric fire doors, maintenance requirements for the operator and release mechanism are part of the compliance obligation.
- Wiring and integration specification: Documents how the electric components connect to the building’s fire detection and alarm system. This is necessary for the fire safety engineer and the installer to verify that the release trigger functions correctly.
- EPD (Environmental Product Declaration): Required for BREEAM and LEED projects and increasingly requested by clients and developers. An EPD is an information document based on a life cycle assessment; it is not an environmental label or sustainability award, but it provides the data needed for green building certification calculations. Metacon-Next published EPDs for eleven of its main product lines in 2025.
- Country-specific test extensions: For projects in Germany, France, Switzerland, or Austria, national requirements may apply in addition to the CE marking. Manufacturers who have conducted additional tests for these markets can supply the corresponding documentation.
Requesting all six categories at the specification stage, before order placement, is standard due diligence. A supplier who cannot provide the classification report for the specific electrified configuration being specified — including the explicit EI1 or EI2 designation and the tested duration — is not in a position to deliver a compliant product. Architects who request a quotation from Metacon-Next receive access to the full documentation set, including EPDs for applicable product lines and classification reports that cover the tested configurations relevant to the project.
If you are working on a project that requires an electric fire door with a verified EI1 or EI2 classification and complete technical documentation, the Metacon-Next team can confirm which tested configurations are available for your opening dimensions and fire resistance requirement. Whether a specific classification is sufficient for your compartmentalisation situation depends on a project-specific fire safety calculation — a qualified fire safety engineer or the local authority is best placed to determine this. All fire-rated industrial door products are supplied exclusively through certified dealers and installers, ensuring that the installation is warranted alongside the product itself. You can also learn more about the company’s manufacturing approach and certification philosophy on the about Metacon-Next page.
