Hello. If your business uses an automatic entrance, include it in your regular safety and maintenance planning.
Automatic doors support smooth access for shops, offices, healthcare premises, schools and public buildings. They also combine moving parts, electrical controls, safety sensors and, in many cases, access control systems.
A small fault can create a serious problem. The door may close unexpectedly, fail to open during an emergency, restrict access for disabled users or interfere with your building security.
Planned maintenance helps reduce these risks. It also provides clear records that show how your business manages its responsibilities.
Why automatic door maintenance matters
Automatic doors operate frequently. A busy retail entrance may complete thousands of cycles each week. Components can wear gradually without creating an obvious fault.
Common issues include:
- Dirty or misaligned sensors.
- Worn rollers, belts, hinges or guide tracks.
- Damaged safety edges.
- Delayed or unreliable activation.
- Incorrect opening or closing speeds.
- Faults with emergency release equipment.
- Weak batteries or backup power.
- Problems linking the door to a fire alarm.
- Access control faults.
- Doors that do not close, lock or secure correctly.
A door that still opens and closes is not necessarily operating safely. Maintenance must check the complete system, not just whether the entrance is working.
CIBSE guidance for automatic doors highlights the importance of suitable safety devices, regular checks, maintenance records, manuals and emergency operation. The CIBSE guidance on automatic doors and gates is a useful reference for facilities managers and property operators.
Check the safety sensors
Safety sensors help prevent impact, trapping and entrapment. They must detect people approaching the door and identify anyone within the movement area.
During a professional service, an engineer should check:
- Sensor condition.
- Sensor alignment.
- Detection range.
- Activation response.
- Presence detection.
- Door stop and reverse functions.
- Closing speed and delay.
- Obstructions around the threshold.
- Performance in different lighting conditions.
Keep sensor lenses clean. Dust, dirt, condensation, stickers and physical damage can affect performance.
Staff should report any door that:
- Opens late.
- Closes while someone is passing.
- Fails to detect wheelchair users, children or slower-moving people.
- Stops suddenly.
- Makes unusual noises.
- Requires repeated approaches before opening.
Do not adjust safety sensors without the correct knowledge. Incorrect settings may create a hidden hazard.
Test emergency release and failsafe operation
Automatic doors may be connected to access control, a fire alarm, a break-glass unit or a backup battery. These connections must work together correctly.
The correct emergency response depends on the door’s location, locking arrangement, fire strategy and risk assessment. Do not assume that every automatic door should behave in exactly the same way.
For doors on an escape route, confirm that people can leave safely during a power failure or emergency. Depending on the design, this may involve:
- Manual breakout or manual opening.
- Fail-safe release.
- A suitable emergency exit device.
- Break-glass release.
- Request-to-exit equipment.
- Fire alarm interface.
- Battery backup.
- Clearly marked controls.
A fail-safe lock generally releases when power is removed. A fail-secure lock remains locked when power is lost, but the door must still allow safe exit through suitable mechanical or emergency hardware.
A competent engineer should test the complete arrangement. This may include simulating a power failure, activating the emergency release and checking the fire alarm interface.
Record the outcome. Include the door location, test performed, result, defects identified and remedial action required.
Never disable a door’s safety feature to keep the entrance operating. If a fault affects safe operation, isolate the equipment and make the entrance safe until repairs are completed.
Protect accessibility and inclusive access
Automatic doors can make buildings easier to use. They assist wheelchair users, people with mobility difficulties, parents with pushchairs and anyone carrying equipment or goods.
Poor maintenance can remove those benefits.
Check that:
- The approach sensor detects users from normal angles.
- The opening speed is suitable.
- The hold-open time allows safe passage.
- The clear opening width remains adequate.
- The threshold is free from trip hazards.
- The door does not close before a user has passed.
- The access control reader is positioned correctly.
- The entrance remains available when it should.
- Manual release arrangements are clear.
Accessibility is not only about installing an automatic door. The door must continue to operate reliably for all expected users.
Consider the needs of your site. A school, care setting or healthcare building may need longer opening times and different sensor arrangements from a small office. A retail entrance may experience more frequent use and greater exposure to dirt, weather and impact.
Include these factors in the maintenance plan.
Maintain access control systems properly
Many commercial entrances combine automatic doors with access control systems. The access reader may control entry, while the door operator manages movement and safety.
This creates additional points to check.
A maintenance visit should review:
- Reader operation.
- Credentials and access permissions.
- Door position monitoring.
- Lock release.
- Request-to-exit devices.
- Door-closed signals.
- Forced-door alarms.
- Fire alarm release.
- Emergency release.
- Integration with CCTV or intercom systems.
- Battery and power supply condition.
A door can appear to be functioning while the security system is not reporting its status correctly. For example, a failed door position contact may prevent an alarm from being generated when the door is held open.
Dragon also maintains related security services, including access control and other commercial security solutions. Integrated maintenance helps reduce the risk of separate systems being checked in isolation.
Keep clear maintenance records
A service record provides an important operational history. It should be easy for a facilities manager, responsible person or contractor to understand.
For each automatic door, record:
- Site and door location.
- Door type and manufacturer.
- Model and serial number where available.
- Installation date where known.
- Whether the door is on an escape route.
- Safety devices fitted.
- Access control connections.
- Fire alarm interfaces.
- Inspection dates.
- Test results.
- Defects and recommended actions.
- Parts replaced.
- Engineer details.
- Next service date.
Keep the records with your wider building compliance information. They may support fire risk assessments, health and safety reviews, insurance queries and budget planning.
A log should not simply state “door checked”. It should show what was tested and whether the equipment passed.
Why planned preventative maintenance is better
Reactive repairs only address faults after they occur. This can lead to:
- Unplanned closures.
- Disruption to customers and staff.
- Restricted access.
- Emergency contractor costs.
- Damage to other door components.
- Security weaknesses.
- Difficulties arranging repairs at busy times.
Planned preventative maintenance identifies wear before it becomes a breakdown. It also gives you a predictable service schedule and a clearer maintenance budget.
The correct frequency depends on the manufacturer’s instructions, usage, environment, door design and risk assessment. High-traffic entrances and doors on escape routes may need more frequent attention than lightly used internal doors.
CIBSE guidance refers to regular user checks, maintenance in line with manufacturer recommendations and an annual safety inspection for automatic sliding doors. Treat this as a planning reference, not a replacement for a site-specific assessment.
For Record Door Automation equipment, follow the relevant manufacturer documentation. If the door’s history or model is unknown, arrange a professional inspection before setting the maintenance schedule.
A practical maintenance checklist
Start with these actions:
- List every automatic door on your premises.
- Identify entrances, internal doors and escape-route doors.
- Check whether each door connects to access control or fire systems.
- Find the manufacturer manuals and previous service records.
- Ask staff to report unusual movement, noise or delays.
- Keep thresholds, tracks and sensor areas clear.
- Schedule professional maintenance based on risk and usage.
- Test emergency release arrangements under controlled conditions.
- Record every inspection, defect and repair.
- Close out safety-critical faults without delay.
Do not wait for a door to fail completely before arranging a service.
