High‑Security Automatic Doors: Secure Without Blocking Escape
Automated doors must resist unauthorised entry without trapping anyone during an emergency. The objective is clear: robust perimeter security, instant and intuitive egress, and inclusive operation for every user. Achieving this requires the right hardware, smart control logic, and correct integration with the building’s life‑safety systems.
This guide covers cylinders, electric strikes, maglocks, operators and access control, with practical points from BS EN 16005. Access Automation brings 15+ years of engineering‑led design, risk assessments and tailored solutions for commercial and domestic sites. Start with our practical BS EN 16005 Automatic Door Safety Audit Checklist to frame your project.
Standards, Fire Strategy And Inclusive Access (BS EN 16005, Equality Act)
BS EN 16005 defines safety for powered doors, including opening forces, sensor coverage, approach speeds and safeguarding zones. Your locking method must not defeat these protections. Operators, sensors and guarding must work together so the door always reacts safely to people and obstacles.
Lock selection must align with the site fire strategy and evacuation plan. On alarm, escape routes must stay clear and obvious. Consider inclusive design under the Equality Act (and guidance such as BS 8300‑2 and Approved Document M): consistent heights, easy‑grip hardware, low effort and predictable behaviour for all users.
Locking Options: Cylinders, Electric Strikes And Maglocks
Electric strikes release a latch in the frame and work well with lever handles, panic bars and swing operators.
- Choose fail‑secure for perimeter protection and fail‑safe for life‑safety routes following risk assessment.
- Use pre‑load tolerant models where weather seals or pressure can bind the latch.
- Common pitfalls: misalignment, weak frames and poor cabling. Mitigate with reinforced keeps, proper fixings and monitored contacts (latch and door position).
Maglocks hold with an electromagnet and are inherently fail‑safe (they release on power loss), which often suits escape routes.
- Shearlocks offer higher holding force but demand accurate installation and rigid frames.
- Specify bond‑status monitoring and door position contacts for reliable reporting and alarms.
- Provide a manual key override using high‑security cylinders with managed key control for auditability. Learn more in Fail‑Safe Vs Fail‑Secure Locks and our Mul‑T‑Lock overview.

Pairing Locks With Door Operators: Swing, Sliding And Aluminium Entrances
Automatic swing doors typically pair a latch with a monitored electric strike. The operator sequences release and opening so the leaf moves cleanly after unlock.
- On escape routes, add compliant panic hardware for a mechanical exit even if power or controls fail.
- Use door position and lock status monitoring to prevent door‑ajar faults and to improve diagnostics.
- Where seals or wind load create pre‑load, consider latch retraction or pre‑load tolerant strikes.
Automatic sliding doors use maglocks or purpose‑built motor locks.
- Maglocks need rigid reinforcement and precise alignment to handle wind and stack effects.
- Aluminium entrance systems benefit from robust keep plates, concealed cabling and monitored contacts.
- Exterior and high‑traffic doors often require higher‑duty hardware and tighter access‑control integration.
Access Control And Monitoring: Secure Entry, Simple Exit
Access control defines who can enter and when, and coordinates with the operator to unlock and open safely.
- Use time profiles, readers and controllers to manage locked/unlocked states.
- Add audit trails, door position contacts and lock monitoring to detect forced entry or door‑ajar conditions.
- Reduce tailgating with anti‑passback, vestibules and appropriate reader placement.
- Support accessibility and hygiene with touchless triggers, wave‑to‑open plates, request‑to‑exit sensors and radar.
- Intercoms and CCTV provide live verification for visitors and deliveries. Explore options on our Commercial Access Control page.
Emergency Egress That Always Works
Design so occupants can always escape, even under fault conditions.
- Link the fire alarm to drop power to maglocks or to trigger strikes to release.
- Provide local override via green break‑glass units (BGUs) or emergency door releases, sited clearly on the approach side.
- Where appropriate, fit mechanical panic bars as the final fail‑safe path.
- Keep escape operations obvious and consistent with clear signage and regular drills.
- Review fail‑safe vs fail‑secure by door function and area risk. Test on a schedule and document results so staff know how to operate the door during an incident.
Power Cuts, Weather And Resilience Planning
Know how each lock behaves without mains power and plan continuity around it.
- Maglocks release on power loss; electric strikes are usually fail‑secure unless specified fail‑safe.
- Use UPS backup for controllers and operators to maintain safety and continuity for a defined period.
- Employ monitored relays and alerts so teams can respond quickly to state changes.
- For exterior doors, account for wind, stack effect and freezing. These affect seal pressure and closing speeds; adjust hardware, seals and control logic accordingly. See Wind And Stack Effect: Door Choice.
- Agree a resilience plan with clear thresholds for switching to manual mode.

System Designs By Building Type
Healthcare: prioritise reliable hygiene and patient flow. Use touchless activation, antimicrobial options and supervised egress to reduce cross‑contact while keeping routes open.
Education: choose durable hardware, clear zoning and fast, safe evacuation. Main entrances benefit from monitored strikes or motor locks with robust frames.
Retail and offices: deploy vestibules, anti‑tailgating measures and monitored locking on public‑facing entrances, balancing throughput with security.
Residential and mixed‑use: keep operation simple, use high‑security cylinders with controlled keys, and ensure every occupant can exit without tools or keys.
Inclusive Design: DDA‑Aligned Hardware And Touchless Operation
Door furniture should be easy to grip and within consistent reach.
- Select pull handles and thumbturns that aid users with reduced dexterity.
- Mount at consistent heights with clear approach space and low activation effort.
- Ensure sensor coverage, approach speeds and forces meet BS EN 16005. Touchless triggers assist users who cannot push or pull.
- Use bold, legible signage that explains how to open and how to exit, including the location of any emergency release.
- Align with Equality Act principles and relevant guidance such as BS 8300‑2 and Approved Document M.
Commissioning, Handover And Ongoing Maintenance
Commissioning verifies safety and performance before handover.
- Test sensors, opening forces and guarding; prove egress under alarm and BGU release.
- Confirm door and lock monitoring, access control logic and event reporting.
- Provide settings, drawings, logbooks and maintenance schedules so caretakers and FM teams can manage the system.
Plan routine inspections based on duty cycle.
- Check alignment, door sag, strike keeps, maglock brackets and sensor drift.
- Record results and fix minor issues before they become faults. For visit frequency, read How Often Should Automatic Doors Be Serviced?
- Access Automation provides responsive call‑outs when needed.
Project Planning: Surveys, Key Control And Cost Of Ownership
Start with a site survey to confirm clear openings, frame strength, power and fire interfaces, then match the right operator, lock and access control to the door type and environment. Early coordination avoids redesign and shortens installation time.
- Adopt a managed key hierarchy for manual overrides and secure areas, backed by high‑security cylinders.
- Assess ten‑year costs: energy use, parts, servicing and uptime to minimise total cost of ownership.
- Access Automation can share relevant case studies and a clear plan for dependable performance throughout the system’s life.

FAQs
Can an automatic door be highly secure and still meet BS EN 16005?
Yes. With the right lock, operator sequencing and sensors, you can achieve strong security while maintaining safe forces and safeguarding zones. Emergency egress must remain instant and obvious.
Which is better for escape routes: maglocks or electric strikes?
It depends on the door and risk. Maglocks are naturally fail‑safe and suit many escape routes. Strikes can also work if paired with compliant panic hardware and the correct fail mode.
How do automated doors release on a fire alarm?
The fire interface drops power to maglocks or signals strikes to release. Green break‑glass units provide local override. The door should allow a clear, mechanical exit if controls fail.
What happens during a power cut?
Maglocks release; strikes may stay locked unless specified fail‑safe. A UPS can maintain safe operation for a set period. We design behaviour around your risk and security needs.
How often should we test and service the system?
Follow a planned schedule based on usage. Check safety sensors, egress, alignment and monitoring at each visit. Keep records and act on minor issues early.
Do we need special handles for DDA compliance?
Yes. Choose easy‑grip handles and compliant thumbturns at correct heights. Clearances, reach and activation force must support all users, including wheelchair users.
Can access control prevent tailgating without slowing entry?
Yes. Use time profiles, anti‑passback, vestibules and CCTV or intercom verification where needed. Configure the system to match your risk level and throughput.
