Engineering Excellence for Automated Entrances
At Automatic Door Force, we understand that an automatic door is more than just an entryway; it is a complex electro-mechanical system that governs the flow, security, and climate of your building. When these systems fail, the impact on business operations is immediate and severe.
We are not generalist handymen. We are a dedicated team of ADIA-certified engineers specializing exclusively in door automation. From the high-torque brushless motors driving heavy industrial sliders to the delicate microwave radar sensors protecting pedestrian safety in retail environments, we possess the deep technical knowledge required to diagnose, repair, and maintain your assets to BS EN 16005 standards.
Core Engineering Capabilities
Comprehensive diagnostic and repair solutions for all operator types.
Sliding Door Diagnostics
Sliding doors are the workhorses of the UK high street. Common failures involve worn carriage wheels, snapped toothed belts, or "ghosting" caused by sensor drift. We carry extensive stock of Dorma ES-200 and Geze Slimdrive components, allowing us to replace motor gearboxes and control boards on the first visit.
Swing Door Operators
Electro-mechanical and hydraulic swing operators (such as the Record DFA 127) face unique stresses from wind loads and stack pressure. We adjust spring tension, calibrate opening speeds, and replace worn arm linkages. We also fine-tune the "Low Energy" vs. "Full Power" settings to ensure accessibility compliance without compromising safety.
Telescopic & Bi-Parting Systems
For narrow entrances requiring maximum width, telescopic doors use complex reduction pulley systems. Misalignment here causes catastrophic jamming. Our engineers are experts in re-stringing telescopic drive belts and aligning interlock rails to restore smooth, synchronized leaf movement.
Revolving Door Maintenance
Revolving doors are engineering marvels requiring precise calibration. We service the central drive shafts, replace peripheral brush seals to maintain thermal efficiency, and test the collapsible door wings (breakout function) to ensure emergency egress compliance.
The Science of Safety: BS EN 16005 Compliance
Since April 2013, all power-operated pedestrian doors must comply with BS EN 16005. This standard dictates that doors must not exert a force greater than 67N on a person and must have failsafe sensors.
Monitored Safety Beams
We upgrade older systems to "monitored" sensors. The door controller tests the sensor before every closing cycle. If the sensor fails, the door remains open, preventing accidents.
Pocket Screen Hazards
We inspect side-screens to prevent "draw-in" hazards where a person could be trapped as the door slides open. We retrofit protective barriers where necessary.
Finger Entrapment
Essential for swing doors in schools and nurseries, preventing finger entrapment at the hinge pivot point. We install robust finger guards that withstand high-volume use.
Every repair visit includes a complimentary safety audit. If your doors are non-compliant, we provide a detailed risk assessment and retrofit solutions to protect your liability.
Industry Sectors We Serve
Healthcare & NHS
Hospitals require absolute reliability. We prioritize sterile environments, servicing hermetic sealing doors and ambulance bay entrances with minimal disruption to patient care.
Retail & Shopping Centres
High footfall destroys inferior components. We install heavy-duty, reinforced floor guides and high-cycle motors designed to withstand thousands of operations per day.
Transport & Infrastructure
From train stations to airports, we maintain large-scale glazed barriers and ticket hall gates, ensuring passenger flow remains uninterrupted during peak hours.
Frequently Asked Questions
My door opens but won't close. Why?
This is a failsafe mode. It usually indicates a blocked safety beam (check for dirt/stickers on the lenses) or a fire alarm activation. If clear, the activation radar may have a "latched" contact requiring a reset.
Do you repair obsolete door brands?
Yes. While we stock parts for major brands like Dorma, Record, and Geze, we can often source generic compatible motors and controllers for older systems like Tormax or Besam, extending the life of your asset.
Is battery backup necessary?
Absolutely. The Battery Backup Unit (BPU) ensures the door performs its emergency function (opening for escape or locking for security) during a power cut. We test and replace these packs routinely.
How quickly can you attend?
For security-critical issues (e.g., doors stuck open), we aim for a 4-hour response time. For non-urgent repairs, we schedule visits within 24 hours.
