1. Executive Summary
AutoDoors UK operates as a specialized technical service provider dedicated to the maintenance of automated pedestrian door systems across the United Kingdom. Unlike generalist facilities management companies, our operational focus is exclusively on the complex electro-mechanical architecture of automatic doors.
Our mandate is simple: to provide data-driven diagnostics, factory-standard repairs, and legal compliance audits that extend the lifecycle of your assets while mitigating liability risks associated with BS EN 16005 regulations.
Why Choose a Specialist?
Automatic doors are governed by strict safety laws. A general handyman lacks the ADIA (Automatic Door Installation Association) certification required to legally sign off on a repair. Our engineers carry the proprietary diagnostic handsets required to interface with Dorma, Geze, and Record control units.
2. Core Competencies
Our engineering teams are deployed regionally to ensure rapid response times for critical infrastructure. We specialize in the following operator types:
- Linear Sliding Operators
- The standard for retail and high-street environments. We service heavy-duty motors (like the Dorma ES-200) and replace consumable components such as nylon carriage wheels and toothed drive belts.
- Electro-Hydraulic Swing Drives
- Common in healthcare (NHS) and corridors. These units (e.g., Record DFA 127) use a powerful spring return and hydraulic damping. We resolve issues with latching speed, wind load resistance, and arm linkage wear.
- Telescopic Systems
- Engineered for narrow apertures, these systems utilize a complex reduction pulley system to stack door leaves. Our technicians are experts in re-stringing telescopic belts and aligning interlock rails to prevent jamming.
3. Technical Breakdown & Diagnostics
Modern automatic doors are driven by Brushless DC Motors and managed by Microprocessor Control Units. A failure is rarely just "broken"; it is a specific component failure.
Common Failure Points We Address:
- Encoder Errors: If the optical encoder fails, the door loses track of its position and may slam. We replace the motor-gearbox assembly to rectify this.
- Sensor Drift: Microwave radar sensors can drift due to temperature changes or vibration, causing "ghosting". We recalibrate the detection field geometry.
- Battery Backup (UPS) Failure: Essential for fire safety. If the battery creates a "Low Voltage" error, the door may default to an open or locked state depending on the program. We replace these consumable packs.
Operator Comparison for UK Facilities
| Operator Type | Ideal Use Case | Maintenance Frequency |
|---|---|---|
| Sliding (Linear) | Retail High Street, Supermarkets | Bi-Annual (Every 6 Months) |
| Swing (Electro-Hydraulic) | Corridors, Care Homes, NHS | Annual |
| Telescopic | Narrow Entrances, Offices | Bi-Annual (High Wear) |
| Revolving | Hotels, Corporate HQ | Quarterly (Complex) |
4. BS EN 16005 Safety Compliance
Since April 2013, all power-operated pedestrian doors must adhere to BS EN 16005. This standard mandates specific safety features to prevent crushing and impact injuries.
Our Safety Audit Includes:
- Force Testing: Measuring the closing force to ensure it does not exceed 67N (Newtons).
- Monitored Sensors: Verifying that safety beams are "monitored" by the controller before every closing cycle.
- Finger Guards: checking for the presence and integrity of guards on the hinge side of swing doors (critical for schools).
5. Frequently Asked Questions
- What is the response time for emergency repairs?
- For security-critical failures (doors stuck open), we aim for a 4-hour response within our primary coverage zones.
- Do you repair obsolete operators?
- Yes. While we carry stock for current models (Dorma, Geze), we can often source refurbished parts or generic controllers for older systems like Besam or Tormax.
- Is a risk assessment provided?
- Every visit generates a digital service sheet which includes a dynamic risk assessment of the door set.
