Automatic Doors: Complete Guide for Businesses

Automatic doors have become an essential part of modern commercial buildings. From shops and hotels to offices, hospitals and industrial facilities, they provide a convenient, accessible and professional entrance while helping businesses manage the movement of people more efficiently.

However, choosing an automatic door involves considerably more than deciding how the entrance should look. The type of door, available space, expected pedestrian traffic, opening method, safety systems, accessibility requirements, energy efficiency and integration with other building systems should all be considered before installation.

Modern automatic doors can also work together with access control systems, allowing a business to combine convenient pedestrian movement with controlled entry to restricted areas.

In this complete guide, we explain how automatic doors work, the principal solutions available for businesses, where they can be used, the safety and access technologies involved and what to consider when choosing, installing and maintaining an automatic entrance.

What Is an Automatic Door?

An automatic door is a powered entrance system that opens and closes without requiring the user to operate the door manually.

Depending on the installation, the door can be activated by:

• Motion sensors.
• Presence sensors.
• Push buttons.
• Remote controls.
• RFID cards or tags.
• Keypads.
• Access control systems.
• Other authorised activation devices.

Once activation occurs, the automation controls the opening movement and keeps the entrance available for the required period before closing it again.

The result is an entrance that can accommodate a continuous flow of people while reducing the need for physical contact with doors and handles.

How Do Automatic Doors Work?

Although the exact mechanism varies according to the type of door, a typical automatic entrance combines several components.

Door Operator

The operator provides the mechanical movement required to open and close the door. Its specification must correspond to the dimensions, weight, configuration and expected frequency of use of the entrance.

Control Unit

The electronic control unit manages the operation of the system. It processes signals from sensors and other activation devices and controls functions such as opening, closing, timing and operating modes.

Activation Sensors

Sensors detect an approaching user and instruct the system to open the entrance automatically.

Safety Sensors

Safety detection helps prevent the door from closing when a person or obstruction remains within the movement or passage area.

Door Leaves and Mechanical Components

Depending on the system, these may include glass or other door leaves, tracks, guides, rollers, arms and other components required for controlled movement.

These elements need to operate as one correctly configured system. This is one reason why professional specification and installation are important for both reliability and safety.

Main Types of Automatic Doors

There is no single automatic-door configuration suitable for every building. The correct solution depends on the entrance dimensions, available space, pedestrian flow and intended use.

Automatic Sliding Doors

Automatic sliding doors are among the most familiar solutions for commercial entrances. One or more door leaves move horizontally to create the opening.

They are particularly suitable for locations such as:

• Retail shops.
• Supermarkets.
• Hotels.
• Office buildings.
• Healthcare facilities.
• Commercial premises.

Because the leaves move sideways rather than projecting into the passage area, sliding systems make efficient use of the space around the entrance.

Controlportas already provides dedicated automatic glass door solutions for commercial applications. Our existing guide to automatic glass doors for modern businesses explores this particular application in greater detail.

Automatic Swing Doors

A swing automation opens a hinged door in a similar movement to a conventional manually operated door.

This type of system can be useful where the architecture of the building or an existing entrance makes a sliding system impractical.

Depending on the project, automation may also provide a way of improving an existing entrance without completely redesigning the opening.

Specialised Automatic Entrances

Some buildings require configurations designed around particular traffic, architectural or operational requirements. In these cases, the most appropriate solution should be determined after assessing the actual entrance rather than selecting equipment solely from its appearance or specification sheet.

Automatic Glass Doors for Commercial Buildings

Glass is particularly popular for automatic commercial entrances because it combines visibility with a contemporary architectural appearance.

For shops, showrooms, hotels and offices, an automatic glass entrance can create a welcoming transition between the exterior and interior while allowing customers to see into the premises.

Automatic glass doors can be particularly useful when businesses want to combine:

• A modern appearance.
• Convenient customer access.
• Good visibility.
• Efficient pedestrian circulation.
• Compatibility with access control.

Where Are Automatic Doors Used?

The versatility of automatic doors makes them suitable for a broad range of commercial and institutional environments.

Shops and Retail Premises

A retail entrance may handle a substantial number of customers throughout the day, including people carrying shopping bags, pushing trolleys or accompanying children.

Automatic opening makes entry and exit easier while creating a more fluid customer journey.

Hotels

Hotel entrances need to accommodate guests carrying luggage while maintaining an attractive and professional appearance. Automatic doors can provide convenient access without requiring guests to handle a door while carrying bags.

Office Buildings

In offices, automatic doors can form part of a wider entrance-management system and can be combined with electronic access control where access needs to be restricted to authorised employees or visitors.

Hospitals and Healthcare Facilities

Healthcare environments frequently require entrances that allow staff, patients, wheelchairs, equipment and trolleys to move through efficiently.

Touch-free activation can also reduce unnecessary contact with door handles in high-traffic environments.

Restaurants and Hospitality

Automatic entrances can improve accessibility and make customer movement easier, particularly at busy periods.

Commercial and Industrial Buildings

Automatic pedestrian doors can also be used at reception areas, administrative entrances and controlled internal access points within larger commercial and industrial premises.

Benefits of Automatic Doors for Businesses

Convenience

The most immediate benefit is straightforward: users do not need to open the door manually.

This is particularly useful for people carrying objects, customers with shopping trolleys, staff transporting equipment and visitors with limited mobility.

Improved Accessibility

An appropriately designed automatic entrance can make access considerably easier for wheelchair users, people with reduced mobility and others who may find manually operated doors difficult to use.

Accessibility should be considered as part of the overall entrance design rather than simply as an additional feature added after installation.

Efficient Pedestrian Flow

In high-traffic environments, automatic doors help maintain a continuous movement of people through an entrance.

This can be especially valuable for retail, hospitality, healthcare and other premises that experience concentrated periods of pedestrian traffic.

Professional Appearance

A well-designed automatic entrance can contribute to the overall appearance of a commercial building and create a modern first impression for customers and visitors.

Reduced Physical Contact

Sensor-activated entrances reduce the need for users to touch handles or push doors open.

Integration with Building Security

An automatic door does not have to remain freely accessible at all times. It can be incorporated into an electronic access strategy so that entry is controlled according to the needs of the building.

Automatic Doors and Access Control

One of the most useful characteristics of modern automatic doors is their ability to work with electronic access control systems.

For example, an office entrance might open automatically during public opening hours but require an authorised credential outside those hours.

Depending on the installation, access can be authorised through technologies such as:

• RFID cards.
• Electronic tags.
• Keypads.
• Intercom systems.
• Smartphones.
• Other electronic credentials.

This means businesses do not necessarily need to choose between convenient automatic access and controlled security. The two functions can form part of the same entrance solution.

For businesses that also need to manage vehicles, the same broader access strategy can incorporate automatic barriers at car parks and vehicle entrances.

Safety Is a Fundamental Part of an Automatic Door

An automatic door moves without the user physically controlling it, so safety detection and correct configuration are fundamental parts of the installation.

The system needs to detect people using or approaching the entrance and manage the door movement appropriately.

Presence Detection

Safety sensors can monitor relevant areas around the doorway so that the system recognises when somebody remains within the passage or movement zone.

Controlled Opening and Closing

The movement, timing and behaviour of the door need to be configured for the particular installation and expected users.

Regular Safety Checks

Sensors and safety functions should continue to operate correctly throughout the service life of the door. They should therefore be included in routine inspection and maintenance rather than assumed to remain correctly configured indefinitely.

Automatic Doors and Energy Efficiency

Commercial entrances can have a significant effect on the interaction between indoor and outdoor environments, particularly when they experience frequent pedestrian traffic.

An automatic door opens when access is required and closes afterwards, rather than depending on every user to remember to close the entrance manually.

However, the actual energy performance of an entrance depends on several factors, including:

• How frequently the door opens.
• How long it remains open.
• The size of the opening.
• The building's heating or cooling requirements.
• The configuration and condition of the door.

Correct configuration therefore matters. Keeping a door open unnecessarily for longer than required can undermine some of the advantages of automatic operation.

How to Choose the Right Automatic Door

The best automatic door is not necessarily the largest, fastest or most sophisticated system available. It is the one correctly matched to the building and its users.

1. Analyse Pedestrian Traffic

Consider how many people normally use the entrance and whether traffic is relatively constant or concentrated into particular periods.

2. Measure the Available Space

The physical dimensions and architecture of the entrance influence which door configurations are practical.

A sliding door requires sufficient lateral space for the leaves to move, while a swing system requires an appropriate movement area.

3. Consider the Users

A public retail entrance has different requirements from a restricted staff entrance or an internal office door.

Consider accessibility, trolleys, wheelchairs, luggage, deliveries and any other regular use of the entrance.

4. Determine the Required Access Level

Ask whether the entrance will:

• Remain freely accessible during business hours.
• Require employee credentials.
• Allow visitor access through an intercom.
• Operate differently at different times of day.
• Form part of a wider building security system.

5. Consider Frequency of Use

A busy commercial entrance requires equipment capable of handling its expected workload reliably.

6. Plan for Maintenance

Maintenance should be considered before the equipment is selected. Access to components, availability of technical support and suitability for long-term servicing all influence the total value of an installation.

Installing an Automatic Door

A professional installation begins before the equipment reaches the site.

The entrance should first be assessed to determine factors such as:

• Opening dimensions.
• Available installation space.
• Door configuration.
• Pedestrian flow.
• Electrical requirements.
• Activation method.
• Safety requirements.
• Access control integration.
• Expected frequency of operation.

Once the correct solution has been selected, the automation, door components, sensors and control equipment can be installed and configured as an integrated system.

Testing and final adjustment are important because reliable automatic operation depends not only on the quality of the components but also on how they are installed and configured.

Automatic Door Maintenance

Automatic doors may operate hundreds of times during a busy working day. Moving components, sensors and electronic equipment therefore need periodic inspection and maintenance.

A preventive maintenance programme may include:

• Checking door movement.
• Inspecting tracks, guides and moving components.
• Testing activation sensors.
• Testing safety detection.
• Checking electrical connections.
• Inspecting the operator and control equipment.
• Checking door alignment.
• Testing access control integration where installed.
• Cleaning components where necessary.
• Adjusting operating parameters when required.

Preventive maintenance can identify developing problems before they result in a complete failure of the entrance.

Common Automatic Door Problems

The Door Does Not Open

A door that fails to open can have several possible causes, including an activation problem, power interruption, control fault or another condition preventing normal operation.

Because an automatic entrance combines electrical, electronic and mechanical systems, proper diagnosis is preferable to repeatedly attempting to reset or force the equipment.

The Door Opens but Does Not Close Correctly

This can occur when sensors detect an obstruction or when the system requires adjustment or technical inspection.

The Door Opens or Closes Irregularly

Intermittent behaviour can indicate problems with sensors, controls, alignment or mechanical components.

The Door Makes Unusual Noises

Grinding, scraping, knocking or other new noises should be investigated. They can indicate wear, incorrect alignment or another mechanical issue.

The Door Moves More Slowly Than Before

A noticeable change in operating speed can be an early indication that the system requires inspection or maintenance.

Should an Automatic Door Be Repaired or Replaced?

A fault does not automatically mean that the entire entrance needs to be replaced.

Repair may be appropriate when:

• The overall system remains in good condition.
• The problem is limited to a serviceable component.
• Suitable replacement parts remain available.
• The existing entrance still meets the operational needs of the business.

Replacement or modernisation may make more sense when:

• Failures are becoming frequent.
• Important components are obsolete.
• The entrance no longer suits current traffic requirements.
• The business requires newer access-control capabilities.
• The existing system no longer provides the required performance.

A technical assessment can determine whether repair, modernisation or replacement provides the most appropriate long-term solution.

Automatic Doors for Different Types of Businesses

Retail

Priorities normally include easy customer access, efficient pedestrian flow, visibility and reliable operation during opening hours.

Hotels

Convenient access for guests with luggage, appearance and dependable operation are particularly important.

Offices

Integration with staff and visitor access control may be a major consideration.

Healthcare

Accessibility, high pedestrian traffic and easy movement of wheelchairs and equipment can influence the entrance design.

Industrial and Commercial Facilities

Reception areas and controlled pedestrian entrances may need to integrate with wider site-security systems.

This illustrates why automatic doors should be specified around the actual application rather than treated as a one-size-fits-all product.

Automatic Door Buying Checklist

Before choosing an automatic door for your business, consider the following questions:

• What type of building will the door serve?
• How many people use the entrance each day?
• Is the entrance public or restricted?
• What clear opening width is required?
• Is there sufficient space for a sliding system?
• Does the entrance need to accommodate wheelchairs, trolleys or luggage?
• Will access control be required?
• What safety detection is appropriate?
• How intensively will the door operate?
• Who will provide future maintenance and technical assistance?

Answering these questions before selecting the equipment makes it considerably easier to identify an appropriate solution.

Frequently Asked Questions About Automatic Doors

How does an automatic door know when to open?

An automatic door can use sensors or another activation method to detect or authorise a user. The control system then activates the operator and opens the door.

Are automatic doors suitable for small businesses?

Yes. Automatic doors are not limited to large shopping centres or hospitals. The appropriate system depends on the entrance, available space, expected traffic and requirements of the individual business.

Can an automatic door be connected to access control?

Yes. Automatic doors can form part of an electronic access control system so that only authorised users can activate the entrance when restricted access is required.

Are automatic glass doors suitable for shops?

Yes. Automatic glass doors are widely suited to retail environments because they can combine visibility, convenient customer access and a contemporary commercial appearance.

Do automatic doors require regular maintenance?

Yes. Periodic maintenance helps ensure that mechanical components, sensors, controls and safety functions continue to operate correctly.

Why has my automatic door started opening slowly?

A change in operating speed can have several mechanical or control-related causes. If the behaviour has changed noticeably, the system should be inspected rather than simply having its settings altered without identifying the cause.

Can an existing door be automated?

In some situations an existing entrance can be automated, particularly with suitable swing-door configurations. Whether this is appropriate depends on the condition, dimensions and design of the existing door and should be assessed technically.

Which is better: an automatic sliding door or an automatic swing door?

Neither configuration is universally better. Sliding doors can be particularly efficient for busy commercial entrances where suitable lateral space exists, while swing automation can be appropriate for other architectural layouts or existing entrances. The correct choice depends on the building and how the entrance will be used.

Can automatic doors be used with RFID cards?

Yes. RFID credentials can be incorporated into an access control system that authorises the automatic door to open for approved users.

Can automatic doors improve accessibility?

An appropriately designed automatic entrance can make access easier for wheelchair users and people with reduced mobility by removing the need to manually operate the door.
