Chapter 23. Automatic Folding and Swing Doors
The problem: A retrofit ward has narrow corridors, no wall parking space for sliding leaves, and fire doors that must self-close. Sliding is impossible. Folding or automated swing — and how do you keep it safe and accessible?
Mechanisms compared
Automatic folding doors use a hinged two-panel leaf that folds as it opens, either sliding on an overhead track or driven at the hinge. EN 16005 explicitly covers "folding doorsets with a horizontally moving door leaf".
- Advantage: opens a wide clear passage from a narrow structural opening; needs almost no side parking space and no swing arc into the corridor.
- Disadvantages: multiple pinch and shear points at the hinges and the folding edge; more hinges, pivots and carriers to maintain; slower and noisier than a clean swing door. Finger-trap protection at the hinge side is mandatory in healthcare use.
Automatic swing doors retrofit a conventional hinged leaf with an electro-mechanical operator (header-mounted arm or integrated drive). EN 16005 covers swing doorsets, and the safety regime differs sharply by operating mode:
- Low-energy mode: reduced opening/closing speeds and forces, intended where many users need special protection (elderly, infirm, children). In low-energy operation, protection with additional safety sensors is required only in individual cases — the slow, low-force movement is itself the safeguard. Hold-open times must be long enough for slow users.
- Full (automatic) mode: normal speeds and forces. Here, per EN 16005 guidance used by major manufacturers, the swing range of the door must always be secured by safety sensors — presence sensors on both sides of the leaf covering the sweep area, since a person standing in the arc will be struck.
| Folding | Swing (low-energy) | Swing (full automatic) | |
|---|---|---|---|
| Space needed | Minimal | Full swing arc | Full swing arc |
| Clear width from opening | High | Up to full leaf width | Up to full leaf width |
| Pinch/shear hazards | High (hinges, folding edge) | Low | Moderate (sweep area) |
| Sensor requirement | Finger-trap + presence | Case-by-case | Always, both sides |
| Maintenance | Higher | Low | Low |
| Fire-door compatibility | Rare | Common (with closer function) | Common |
Applications
- Folding: narrow retrofit corridors, utility rooms, small wards where a sliding pocket is impossible and a swing arc would block the corridor.
- Low-energy swing: patient rooms, consultation rooms, accessible WCs — anywhere users operate the door deliberately via push pad, elbow switch or touchless sensor.
- Full-automatic swing: high-traffic internal entrances where a sliding door cannot fit and traffic justifies the sensor package.
Accessibility and operator selection
For barrier-free access, the combination of operator and actuation device matters as much as the operator: touchless wave sensors, large elbow switches, remote controls or radar activation allow hands-free use. Verify opening force, hold-open time and closing speed against local accessibility rules (e.g. requirements derived from EN 17210 or national equivalents), and confirm the operator provides power-assisted manual mode so the door can still be pushed open on failure.
Trade-off to state plainly: low-energy operators are slower by design. On a busy corridor that frustrates staff; on a patient room door it is exactly what safety requires. Choose the mode for the user group, not for throughput.
Common mistakes
- Running a full-energy operator without swing-area sensors because "the door is slow enough" — a compliance failure under EN 16005.
- Folding doors in dementia or paediatric wards without full finger-trap guards.
- Automating a fire door with an operator that cannot guarantee self-closing on alarm — the operator must release to the closer on fire signal.
- Forgetting that on escape routes, the automated function must fail to a safe, manually operable state.
Recommendation
Default to low-energy swing operators for patient-area hinged doors; reserve folding doors for genuinely space-constrained retrofits with full finger-trap protection; and wherever full automatic mode is used, budget for the complete sensor set and an EN 16005 commissioning test, not just the operator.
