What Are Building Access Control Systems?

What Are Building Access Control Systems?

When you want to keep the right people moving freely and the wrong people out, building access control systems are the backbone of a smart, secure facility. From small offices to sprawling campuses, access control determines who can enter, where they can go, and when they can go there.

What Is an Access Control System?

An access control system is a coordinated set of hardware and software that manages entry to a building or space. At a high level, it authenticates an identity, verifies permission, actuates a lock or door operator, and logs the event. Think of it as a traffic controller for your facility’s thresholds—lobbies, perimeter doors, stairwells, labs, storage rooms, server closets, parking gates, and more.

Core components typically include:

  • Credentials: What a person presents to prove identity—keycards or fobs, mobile credentials, PINs, or biometrics like fingerprints or facial recognition.
  • Readers: Devices that capture and transmit credential data—proximity readers, keypad readers, biometric scanners, intercom stations with video, or multi-technology readers that handle cards and phones.
  • Controllers: The decision-makers. These are panels or edge devices that compare the presented credential against an access policy and decide whether to grant entry.
  • Electronic locking hardware: Electric strikes, magnetic locks, electrified mortise locks, and similar devices physically secure the opening.
  • Door position and request-to-exit (REX) sensors: Provide status and safe egress signaling.
  • Management software: The brain and recordkeeper, where administrators define access levels, schedules, alarms, and reporting.

How it works: A person presents a credential at a reader. The reader passes the data to a controller or to cloud software via a secure connection. The system checks time-based rules and door-specific permissions. If permitted, the controller triggers the door hardware—unlocking a latch, releasing a maglock, or signaling an automatic operator to open. The system logs the event for audits and analytics.

Built for life safety and everyday use

A well-designed system balances protection with life safety and accessibility. That means preserving free egress in emergencies, respecting fire and building codes, enabling safe operation for people with disabilities, and integrating with alarm systems and elevator controls. You should expect modern systems to support “fail-safe” or “fail-secure” behaviors as appropriate for each opening, provide local override for first responders, and allow emergency unlocks when needed.

Where door automation fits

Access control doesn’t exist in isolation. At the door, it must work seamlessly with automatic operators for swing, sliding, and revolving doors, plus safety sensors that detect people in the path of a moving door. When a credential is approved, the access system sends a signal—often a dry contact or relay output—to the door operator. The operator then opens the door, monitors it through position sensors, and safely closes according to configured timing and safety inputs. For busy lobbies, healthcare facilities, retail, or campuses, this integration is what turns a secure entry into a frictionless one.

Types of Building Access Solutions

Access control is not one-size-fits-all. The right mix depends on your risk profile, traffic patterns, budget, and compliance needs. Below are the most common categories you’ll encounter, along with specialty options you can layer on as your facility evolves.

Electronic Keycard Systems

What they are: Keycard and fob systems remain the workhorse of commercial access. They use proximity (125 kHz) or smartcard (13.56 MHz) technologies to store unique identifiers. Users tap or present a card; the reader transmits the ID for verification.

Why they’re popular:

  • Simplicity and speed. Cards are familiar, inexpensive, and fast to issue or revoke.
  • Scalability. From a single door to thousands across multiple sites, card-based systems scale well.
  • Compatibility. Many multi-tech readers can handle legacy prox cards and modern smart credentials, easing migrations.

Key considerations:

  • Security levels vary. Older prox cards are convenient but easier to clone than encrypted smartcards. Organizations with higher risk should standardize on secure smart credentials.
  • Lifecycle management. Cards get lost. Strong policies for deactivating lost credentials and auditing cardholders help keep risk low.
  • Mobile evolution. Many facilities pair cards with mobile credentials to give users more flexibility while phasing out plastic over time.

Best-fit use cases: Office campuses, education buildings, retail back-of-house, residential lobbies, and anywhere you need dependable, high-throughput entry with manageable cost.

Biometric Access Systems

What they are: Biometric systems verify something you are—fingerprints, facial geometry, iris patterns, or palm vein structures. Modern sensors incorporate “liveness detection” to reduce spoofing and typically encrypt templates rather than storing raw images.

Why they’re compelling:

  • High assurance. Difficult to share or lose, biometrics can raise the security bar compared to cards or PINs alone.
  • Convenience. Hands-free or touch-minimal experiences can speed throughput and keep traffic moving in sensitive areas.
  • Multi-factor ready. Combine biometrics with cards or mobile credentials for step-up security at critical doors.

Key considerations:

  • Privacy and policy. Biometric deployments require clear consent, robust data protection, and adherence to applicable privacy regulations.
  • Environmental fit. Lighting, throughput, and hygiene expectations matter—especially for facial readers or any touch-based sensors.
  • Redundancy. Always provide fallback methods (e.g., a card or mobile credential) for users who can’t enroll or when environmental conditions aren’t ideal.

Best-fit use cases: Data centers, pharmaceutical and R&D labs, executive suites, high-security storage areas, and anywhere that demands strong identity assurance without sacrificing speed.

Cloud-Based Access Management

What it is: Instead of hosting your own server on-site, cloud-based access centralizes administration in a secure, web-managed platform. Edge controllers at the doors connect over the network and continue to function even if the internet drops, syncing events and policies when connectivity returns.

Why it’s gaining traction:

  • Anywhere administration. Add users, adjust schedules, or unlock a door remotely from a browser or mobile app.
  • Faster updates. Software enhancements, security patches, and new features roll out without on-prem maintenance.
  • APIs and integrations. Connect with HRIS, visitor management, identity providers (SSO), video intercoms, building automation, and tenant apps.
  • Simplified deployments. Power-over-Ethernet (PoE) edge controllers reduce panel wiring and cost at many openings.

Key considerations:

  • Cybersecurity posture. Demand strong encryption, role-based access, multi-factor authentication, and clear data retention policies.
  • Uptime and resilience. Look for offline capability at the door and documented recovery procedures for network outages.
  • Cost model. Subscription pricing can be predictable; ensure it aligns with your growth and multi-site needs.

Best-fit use cases: Distributed portfolios, property managers, multi-tenant environments, progressive workplaces, and organizations wanting to reduce on-prem server complexity.

Beyond those three pillars, you’ll frequently layer in:

  • Mobile credentials (BLE/NFC): Let users tap with their smartphone or watch—improves convenience and reduces plastic.
  • Keypad/PIN at low-risk doors: Cost-effective but best used with a second factor in higher-risk scenarios.
  • Video intercom for visitors and deliveries: Streamlines temporary access while preserving an audit trail.
  • Turnstiles and speed lanes: Manage lobby throughput and tie identity to elevator destination control.
  • Elevator and parking controls: Extend access policies vertically and to the perimeter for full-campus coverage.

Benefits of Access Control Systems

Modern access control does more than lock and unlock. It improves safety, operational efficiency, user experience, and even energy performance when paired with automated doors.

Stronger security with clear accountability

With access control, you replace anonymous keys with auditable identities. Every event—valid entry, denied attempt, door forced open—creates a time-stamped record. That audit trail supports investigations, compliance requirements, and continuous improvement. You can tighten policies for sensitive spaces, enforce two-person rules, or set anti-passback constraints to reduce tailgating.

Streamlined convenience for occupants and guests

When access works the way people expect, friction drops. Employees badge once at the lobby turnstile and ride directly to their floor with the right elevator access. Contractors get time-bound credentials that expire automatically. Visitors receive QR codes or mobile passes in advance and glide through the front door after announcing themselves on a video intercom—no paper badges or long lines.

Operational efficiency and lower lifetime costs

Access control centralizes tasks that used to be manual: rekeying locks, collecting keys from former employees, or staffing entrances during busy periods. Cloud administration reduces IT overhead, while standardized hardware and PoE edge devices can simplify installation and maintenance. Over time, better control of loss and liability often offsets the upfront investment.

Data and insight for better facility planning

Event data helps you understand how spaces are used. Which entrances are overloaded at 8:45 a.m.? Are there wings that sit idle after hours? These insights steer staffing, cleaning schedules, and security patrols—and can inform future buildouts, renovations, and lease negotiations.

Health, hygiene, and the non-contact experience

Since COVID-19, many organizations have prioritized non-contact door operation to reduce touchpoints. Access systems can trigger automatic swing, sliding, or revolving doors so occupants don’t need to push or pull. You can add touchless wave-to-open sensors inside for egress, pair with mobile credentials to avoid handling cards, and tune door operators for smooth, hygienic flow. Non-contact doesn’t just feel modern—it can be a meaningful part of your wellness and accessibility strategy.

Accessibility and inclusive design

Automated doors paired with access control support people using wheelchairs, walkers, or strollers—and anyone carrying packages or equipment. Properly configured operators ensure adequate opening time, smooth start/stop motion, and obstacle detection. Integrate with push plates or touchless triggers as needed, and ensure your system supports quick assistance overrides for staff.

Life safety and code alignment

Secure doesn’t mean sealed. Doors must allow safe egress during fire alarms and power failures where required. That’s why professional integrators coordinate access rules with door automation controls, fire alarm systems, and door hardware that’s appropriate for each path of egress. Thoughtful design selects fail-safe or fail-secure behaviors by door type and occupancy.

Energy-conscious entrances

Automatic doors can contribute to energy-conscious operation when tuned correctly—limiting unnecessary air exchange, closing promptly after passage, and, in the case of revolving doors, helping separate interior and exterior environments. Access control helps by preventing doors from standing open unnecessarily, aligning door operator timing with real traffic, and coordinating vestibule behavior.

How access control and automated doors work together (in practice)

  • Signal flow: The access controller’s “grant” signal triggers the door operator, which opens the door within defined safety parameters.
  • Safety sensors: Presence sensors, safety beams, and door position switches ensure the door moves only when it’s safe.
  • Egress logic: Request-to-exit devices (motion sensors or push-to-exit controls) signal the controller for a safe, compliant exit.
  • Monitoring: The system logs door status—held-open alarms, forced-open events, or repeated access denials—so teams can respond quickly.
  • Visitor and delivery workflows: Intercom approval can temporarily release the operator, time-limit door hold-open, and capture video for the audit trail.

Getting that choreography right is where experienced door automation professionals add real value—matching operators, locks, sensors, and control logic to your actual traffic patterns and compliance needs.

Planning considerations for your project

  1. Entry types and volumes. A high-traffic sliding entrance calls for different hardware and timing than a rarely used side door.
  2. Risk zones. Not every door needs the same security level. Reserve biometrics and multi-factor for critical spaces.
  3. Credential strategy. Cards, mobile, biometrics—or a hybrid. Consider your users and change management plan.
  4. Cloud vs. on-prem. Balance IT preferences, cyber posture, and multi-site management needs.
  5. Integration roadmap. Identify adjacent systems—video, intercom, HR, tenant apps, building management—so you can integrate from day one or phase in later.
  6. Future flexibility. Choose readers and controllers that support multiple credential technologies and open standards to avoid dead ends.
  7. Door automation alignment. Engage your door automation partner early to match operator types (swing, slide, revolving), safety sensors, and energy-conscious settings with your access logic.
  8. Service and support. Look for providers with responsive field teams and access to industry-leading products, so you get both dependable hardware and knowledgeable technicians.

Bringing it together: Why the right partner matters

The technology is only half the story; the design and implementation are what make a system dependable day after day. Coordinating access control with door automation requires careful selection of locks and operators, correct wiring and relay logic, smart placement of sensors, and precise tuning. It’s also where nuances—like anti-tailgate logic at a sliding entrance or time adjustments for a revolving door—turn a “working” system into a great one.

A capable partner will:

  • Assess your entrances, traffic patterns, and code requirements.
  • Recommend operator types—automatic and manual, swing, slide, and revolving doors—that fit your space and aesthetics.
  • Specify compatible readers, controllers, locks, and sensors that create a smooth, non-contact flow when desired.
  • Configure schedules and access levels to match your real-world operations.
  • Provide proactive maintenance and swift support to minimize downtime.
  • Align with standard automated door energy compliance and other relevant guidelines for a balanced approach to security, accessibility, and efficiency.

How Can You Troubleshoot an Automatic Door?

How Can You Troubleshoot an Automatic Door?

If you manage a facility or a storefront, automatic door troubleshooting is one of those tasks you don’t think about—until an entryway sticks open during a storm, closes too quickly near a customer, or simply refuses to budge at 8:59 a.m. While power failures, worn rollers, or misadjusted controllers can all cause headaches, one category deserves special attention: safety sensors. These devices tell a door when to open, when to slow down, and—most importantly—when not to move because a person, cart, stroller, or service animal is in the way.

Below, we’ll explain what safety sensors are, why they’re essential, how to recognize early warning signs, and practical steps you can take to test and maintain them for compliance and peace of mind.

Purpose of Door Safety Sensors

Automatic doors create fast, convenient access—but speed without situational awareness is dangerous. Safety sensors provide that awareness, continually watching the approach, threshold, and swing/slide path to prevent unwanted contact and entrapment. In short, sensors:

  • Detect approaching traffic to activate a door at the right time.
  • Create a presence zone to keep a door open while people or objects are in the path.
  • Interrupt or reverse motion when someone enters the danger area mid-cycle.
  • Adapt to changing environments—light, floor reflectivity, and movement—to stay reliable throughout the day.

When a sensor is clean, aligned, and correctly configured, customers enjoy seamless access, and you reduce liability exposure. When a sensor fails or drifts out of adjustment, the door may open late, “ghost” open, or close when it shouldn’t—each a safety and compliance risk.

ANSI Safety Standards

For commercial pedestrian doors in the United States, ANSI/BHMA standards define how doors should behave and how sensors contribute to a safe system. Two standards commonly referenced by facility managers and architects are:

  • ANSI/BHMA A156.10 – Power-Operated Pedestrian Doors. This covers full-energy sliding, swinging, and folding doors typically found at hospitals, airports, supermarkets, and campuses. It specifies activation and safety requirements, including the number and placement of sensors, detection zones, and performance criteria.
  • ANSI/BHMA A156.19 – Low-Energy and Power-Assist Doors. This applies to low-energy swing operators—often used to meet accessibility goals—where doors move more slowly and with lower force but still require appropriate safety methods.

These standards work hand-in-hand with AAADM (American Association of Automatic Door Manufacturers) guidelines, which recommend regular inspections and daily safety checks by the door owner. While technicians perform annual or semi-annual inspections, staff should be trained to perform quick daily tests (more on that below) to catch issues before they become incidents.

Common Types of Safety Sensors

Understanding sensor types helps you diagnose problems efficiently and speak the same language as your service provider. Here are the most common categories you’ll encounter on sliding, swinging, and revolving doors.

1) Approach (Activation) Sensors

What they do: Detect a person or cart approaching an entryway and signal the controller to open the door early enough to maintain a comfortable flow.

Where they are: Mounted above the door or on the header, typically aiming outward.

How they work:

  • Microwave radar sensors detect motion using Doppler technology; great for speed and range, less sensitive to stationary objects.
  • Active infrared (AIR) approach sensors emit and receive IR light, detecting motion and sometimes presence in a defined field.
  • Dual-technology units combine radar for activation with infrared for near-field presence, improving immunity to false triggers.

Common issues:

  • Late opening (field set too small or angled too low).
  • False triggers from moving foliage, busy streets, or reflective surfaces.
  • Seasonal drift due to temperature, mounting vibration, or controller changes.

2) Presence (Safety) Sensors

What they do: Create a safety zone in the door’s swing or slide path to keep it open while people or objects remain in harm’s way and to stop/reverse motion if someone enters the zone mid-cycle.

Where they are: On the header aiming downward, on the door leaf for swing paths, or built into the operator assembly for sliding doors.

How they work:

  • Active infrared presence sensors project a matrix of beams or a “curtain” that recognizes stationary objects—strollers, mobility aids, luggage—as well as people who pause.
  • More advanced units track detection density and compensate for floor reflectivity so dark rugs or shiny terrazzo don’t cause blind spots.

Common issues:

  • Dead zones from dirt on the lens, mis-aimed brackets, or warped covers.
  • Over-sensitivity keeps doors open too long, hurting energy performance.
  • Under-sensitivity risks contact.

3) Threshold (Photoelectric) Beams

What they do: Provide a simple, reliable tripwire across the threshold to prevent a sliding door from closing on a person who steps in at the last second or a swing door from moving when the beam is blocked.

Where they are: Emitter and receiver on opposite jambs or within the header assembly.

Common issues:

  • Misalignment due to bumped posts or settling floors.
  • Intermittent breaks from carts repeatedly striking housings.
  • Sunlight interference in glass vestibules if lenses are not properly shielded.

4) Safety Mats (Less Common in New Installs)

What they do: Pressure-sensitive mats detect weight in the swing path, stopping motion or holding a door open.

Where they are: Floor area adjacent to the door.

Common issues:

  • Edge damage causing unreliable detection.
  • Moisture intrusion leading to nuisance alarms or dead zones.

5) Touchless (Non-Contact) Actuators

What they do: Facilitate non-contact door openings via a wave-to-open gesture or proximity read—popularized during COVID-19 to reduce touchpoints.

Where they are: Wall-mounted near the approach zone or integrated into access control.

Common issues:

  • Gesture distance set too short or too long.
  • Ambient light false triggers if units aren’t filtered or mounted correctly.
  • User confusion without clear signage or iconography.

Maintaining and Testing Sensors

A well-designed automatic door system is only as safe as its ongoing maintenance. Routine cleaning, functional checks, and documented tests are the backbone of compliance and longevity.

Daily Safety Check (2–3 Minutes)

Train opening staff to run a short checklist before business hours:

  1. Visual inspection – Confirm housings are secure, lenses are clean, and nothing obstructs the approach or swing path.
  2. Approach test – Walk toward the door at a normal pace from several angles. The door should open early enough for a comfortable pass without slowing or stopping.
  3. Presence hold-open – Stand motionless in the path; ensure the door remains open. Step out; the door should close after its programmed hold-open time.
  4. Interruption test – As the door begins to close, step into the safety zone; it should stop and reopen immediately.
  5. Threshold beam test – Move a flat object (or your leg) through the beam; the door should not close while the beam is interrupted.
  6. Signage and decals – Verify mandated decals (arrows, “Automatic Door,” “Activate to Open”) are present and readable.

Log the results in a daily inspection sheet. Consistent documentation demonstrates diligence and helps technicians isolate intermittent problems.

Weekly/Monthly Preventive Tasks

  • Clean lenses and covers using a microfiber cloth and a mild, non-ammonia cleaner. Harsh chemicals can haze plastics and reduce sensor performance.
  • Check alignment of photo beams with a simple alignment card or by observing the device indicator LEDs.
  • Verify detection fields by using a standard test target (e.g., a small box or AAADM test object) to confirm the full footprint of the presence zone.
  • Tighten hardware on sensor brackets, headers, and jambs to prevent drift from vibration.
  • Review controller settings (DIP switches or software parameters) for hold-open time, reactivation behavior, and sensor priority.
  • Observe traffic patterns—if customers frequently slow or pause near the doorway, your presence field may need to extend farther or be differently shaped to match reality.

Quarterly/Biannual Professional Inspection

Even with vigilant in-house checks, plan on regularly scheduled qualified service visits. A certified technician will:

  • Perform calibrated field measurement of detection zones against the door’s speed and weight.
  • Test redundant safety functions—for example, ensuring the controller reacts properly if a primary presence sensor fails.
  • Validate fail-safe behavior (door opens safely or stops) during simulated power loss.
  • Review access control integration (badges, intercoms, fire alarm tie-ins) so safety overrides always take precedence.
  • Update firmware or apply manufacturer bulletins and energy-compliance optimizations.

Sensor Failure Warning Signs

Catch these early indicators to prevent downtime and reduce risk:

  • Late or abrupt opening. Approach sensors may be under-aimed or fields too small.
  • Door “hunting” or ghost openings. Overly sensitive radar picking up distant movement or reflections.
  • Door closes with someone nearby. Presence field has blind spots or insufficient density; a lens may be dirty or bracket knocked out of position.
  • Intermittent stop/reverse. Misaligned threshold beam or loose wiring.
  • Excessive hold-open time. Field too large or excessive “presence” sensitivity, often killing vestibule efficiency and HVAC load.
  • Frequent alarms or blinking indicator LEDs. Some sensors display error codes for internal faults, power issues, or blocked optics.
  • Customer complaints. Listen carefully: “It closed too fast,” “I had to wave three times,” or “It didn’t see my stroller” are valuable diagnostics.

When these symptoms appear, start with cleaning lenses and checking alignment. If the behavior persists, escalate to adjustments or a professional service call.

How to Diagnose Like a Pro (Safely)

  1. Isolate the variable. Disable or cover one sensor at a time (following manufacturer safety procedures) to see which input changes behavior.
  2. Use onboard indicators. Most sensors and controllers include status LEDs that show when a field is active, blocked, or faulted.
  3. Check power and wiring. Loose connectors, pinched cables in the header, or shared power supplies can create unpredictable behavior.
  4. Confirm controller logic. Many operators allow you to prioritize inputs (e.g., presence overrides activation); make sure logic has not been inadvertently changed.
  5. Document settings before adjustments. If your change doesn’t help, revert safely.
  6. Lockout/Tagout when necessary. If you need hands inside the header or closer access to the operator, cut power and apply LOTO to avoid unexpected motion.

Important: Never compromise safety to get the door moving. If disabling a sensor would allow unsafe operation—even temporarily—take the unit out of service and call a qualified technician.

When to Replace Safety Sensors

Sensors are durable, but they do not last forever. Consider replacement when:

  • Age and obsolescence. Electronics drift over time; if a sensor is 8–12 years old or manufacturer support has ended, replacement can boost reliability and compliance.
  • Environmental mismatch. If you’ve changed flooring (high-gloss tile) or lighting (sunny vestibule), older sensors may struggle. Newer models offer better immunity and adaptive algorithms.
  • Repeated nuisance faults. If cleaning, alignment, and configuration tweaks don’t resolve intermittent errors, internal components may be failing.
  • Upgrading to touchless access. Post-COVID, many facilities replaced push plates with wave-to-open or integrated sensors to reduce touchpoints while maintaining accessibility.
  • Energy and performance goals. Modern sensors can reduce false holds, improving vestibule performance and meeting automated door energy compliance targets.

When evaluating replacement, look for dual-technology designs (radar + AIR), dense presence curtains, robust sunlight immunity, and clear diagnostics. For swinging doors, consider sensors that protect both the opening and closing arcs, especially in corridors with cross-traffic. For sliding doors, ensure robust threshold protection and side-screening to prevent entry from being misread as exit.

Maintaining and Testing Sensors

Proactive care is the difference between “We got lucky again today” and “Our doors are consistently safe and dependable.” Here’s a deeper program you can adopt or tailor with your provider.

Build a Door-Specific Checklist

Each door has unique geometry, traffic patterns, and surrounding hazards. Create a one-page sheet that lists:

  • Sensor types and brands installed, with serial numbers and firmware where applicable.
  • Field diagrams showing the intended detection zones and any physical constraints (planters, displays, vestibule doors).
  • Test points and expected outcomes for daily and weekly checks.
  • Service history with dates, technician notes, and parts replaced.

Train Multiple Staff Members

Cross-train so coverage doesn’t lapse during vacations or turnover. Include quick “what to do if” scenarios: e.g., if the door won’t close because a beam is blocked, check for carts or signage moved into the path; if the door “freezes,” call the designated service number and post a “Use Other Door” sign.

Keep the Area Clear

Clutter is the silent killer of sensor performance. Seasonal decorations, point-of-purchase displays, or temporary banners often creep into detection zones. Maintain clear setbacks around the approach and swing/slide paths and revisit after merchandising changes.

Document, Document, Document

It’s not just about compliance—it’s about continuous improvement. A simple logbook or digital form helps you spot trends like “false trips at dusk” (perhaps sunlight sweep across the vestibule) or “late opening on rainy days” (dark umbrellas reducing floor reflectivity for certain presence sensors).

Practical Troubleshooting Scenarios (With Likely Causes)

  • Door opens fine in the morning, false-triggers all afternoon.
    Suspects: Sunlight angle hitting lenses, reflections from parked cars, nearby HVAC curtain.
    Action: Add lens hoods, adjust sensor angle, refine radar “reject” area, or add auxiliary shielding.
  • Door sticks open whenever a cart display is near the entry.
    Suspects: Presence field overlapping the display.
    Action: Re-aim presence curtain; reduce field size; relocate the display outside the zone.
  • Door closes on slow-moving individuals with walkers.
    Suspects: Presence density too low; zone too small.
    Action: Increase beam density, extend field farther into the path, verify closing speed/force per standard.
  • Door won’t close at all; indicator LED on beam is off.
    Suspects: Broken wire, power issue, or beam misalignment.
    Action: Check power to the receiver, reseat connectors, realign the beam, replace if non-responsive.
  • Wave-to-open requires multiple attempts.
    Suspects: Gesture distance set too short; IR noise; actuator placed too high/low.
    Action: Adjust activation range, verify clear sightline, add signage with gesture icon.

Compliance, Risk Management, and Customer Experience

Great sensor performance achieves three outcomes:

  1. Compliance with standards (ANSI/BHMA and AAADM guidance), documented by daily checks and scheduled professional inspections.
  2. Lower risk for your business—fewer near-misses, reduced incident probability, and stronger defensibility if something goes wrong.
  3. Better experience—doors open predictably, move smoothly, and minimize contact for hygienic operation, which customers notice and appreciate.

As you refine your program, align sensor tuning with energy goals (limiting unnecessary hold-open time) and accessibility (accommodating varied walking speeds, mobility devices, and visual cues). Modern systems make it possible to be both safe and efficient.

When to Call a Professional

There’s plenty you can do in-house, but call a qualified provider if you encounter:

  • Persistent faults after cleaning and alignment checks.
  • Any contact or near-miss incident—have the system professionally evaluated before returning to service.
  • Controller alarms or error codes you can’t interpret.
  • Hardware damage to sensors, cables, or mounting points.
  • Integration changes (adding access control, touchless actuators, or vestibule sequencing).

Professionals bring calibrated tools, manufacturer software, and experience across thousands of doorways—turning guesswork into data-driven adjustments.
