Automatic Door Course

Lesson 1 • History and Evolution of Automatic Doors

Traces automatic door development from early pneumatic systems to modern sensor-driven units. Establishes context for understanding why current designs and standards exist.

Lesson 2 • Core Components and Their Functions

Identifies motors, controllers, sensors, safety edges, and hardware as the primary building blocks. Understanding each component's role is essential for all subsequent diagnostic work.

Lesson 3 • Types of Automatic Door Systems

Categorises sliding, swinging, revolving, folding, and high-speed doors by application. Connects door type selection to building function and traffic volume.

Lesson 1 • Accessibility and Universal Design Requirements

Explains clear-width, activation reach, and timing requirements for accessible automatic doors. Ensures installations serve users with mobility, vision, and cognitive differences.

Lesson 2 • Documentation and Compliance Records

Establishes procedures for maintaining installation certificates, inspection logs, and service records. Proper documentation protects technicians and building owners during audits.

Lesson 3 • Entrapment and Impact Force Limits

Covers maximum allowable kinetic energy, closing force, and detection zone requirements. Directly informs sensor placement and controller parameter settings covered in later chapters.

Lesson 4 • Risk Assessment and Hazard Identification

Applies structured risk assessment methods to identify mechanical, electrical, and entrapment hazards. Builds the safety mindset required throughout all practical installation and service tasks.

Lesson 1 • Basic Electrical Concepts Review

Covers voltage, current, resistance, and power as applied to door system circuits. Provides the electrical foundation required for all wiring and diagnostic tasks ahead.

Lesson 2 • Using Electrical Test Instruments

Demonstrates safe use of multimeters, clamp meters, and insulation testers on door system circuits. Accurate measurement skills underpin all fault diagnosis covered in later chapters.

Lesson 3 • Low-Voltage Control Wiring

Covers sensor inputs, relay outputs, and communication wiring within door control panels. Low-voltage wiring connects all peripheral devices to the controller covered in the next chapter.

Lesson 4 • Reading Wiring Diagrams and Schematics

Teaches interpretation of ladder diagrams, block diagrams, and terminal layouts used in door controllers. Accurate schematic reading is prerequisite to any wiring or fault-finding task.

Lesson 1 • Microwave and Radar Sensors

Explains Doppler microwave detection principles, coverage patterns, and sensitivity adjustment. Microwave sensors are the most common activation device and form the baseline for sensor study.

Lesson 2 • Sensor Placement and Coverage Mapping

Applies detection zone geometry to plan sensor mounting positions for full coverage without nuisance triggers. Correct placement directly determines system safety and energy efficiency.

Lesson 3 • Access Control Sensor Integration

Covers push-button, card reader, keypad, and biometric inputs that trigger door activation. Integrating access control with door sensors is essential for secure and compliant installations.

Lesson 4 • Safety Edges and Pressure Sensors

Describes contact-based safety edges, pneumatic strips, and pressure-sensitive mats used to prevent entrapment. These devices provide the last line of defence when non-contact sensors fail.

Lesson 1 • Glazing, Panels, and Finishing Hardware

Addresses glass panel handling, gasket fitting, patch fittings, and perimeter seals for frameless and framed doors. Correct glazing and sealing complete the installation to a professional standard.

Lesson 2 • Swing Door Operator Installation

Covers surface-mounted and concealed swing operators, arm geometry, and pivot hardware for in-swing and out-swing doors. Arm geometry directly affects force profiles and safety compliance.

Lesson 3 • Operator Unit Mounting and Drive Connection

Details mounting bracket selection, operator positioning, and belt or gear drive connection to the door panel. Correct drive connection ensures efficient power transfer and reduces motor strain.

Lesson 4 • Track and Carriage Assembly

Covers sliding door track types, carriage roller selection, and assembly sequence for smooth, aligned operation. Proper track setup prevents premature wear and noise complaints.

Lesson 1 • Pre-Commissioning Checks and Safety Tests

Performs mechanical, electrical, and sensor checks before energising the system for the first time. Systematic pre-commissioning prevents damage and ensures safe initial operation.

Lesson 2 • Operating Mode Configuration

Programmes automatic, one-way, exit-only, locked, and low-energy modes to match building requirements. Mode selection determines user experience and access control integration behaviour.

Lesson 3 • Controller Architecture and Interface

Explains controller board layout, DIP switches, parameter menus, and communication ports. Familiarity with the interface is required before any programming or adjustment task.

Lesson 4 • Speed, Force, and Timing Parameters

Sets opening speed, closing speed, hold-open time, and obstacle-detection sensitivity within controller menus. These parameters must satisfy both manufacturer specifications and safety standards.

Lesson 1 • Safety Performance Testing

Measures closing force, kinetic energy, and breakout force against current safety standard limits. Performance testing confirms the door remains compliant between full inspection cycles.

Lesson 2 • Electrical and Sensor Inspection

Tests sensor detection zones, safety edge function, wiring condition, and controller parameter drift. Electrical inspection catches degradation before it causes safety failures or nuisance faults.

Lesson 3 • Maintenance Planning and Scheduling

Develops maintenance intervals based on traffic volume, environment, and manufacturer recommendations. A structured schedule prevents unplanned failures and supports compliance audit readiness.

Lesson 4 • Inspection Reporting and Defect Management

Documents findings, classifies defect severity, and communicates required remedial actions to building owners. Clear reporting protects technicians legally and prioritises safety-critical repairs.

Lesson 1 • Interpreting Controller Fault Codes

Decodes error codes, LED flash patterns, and diagnostic software outputs from common controller platforms. Fault code interpretation is the fastest first step in any electronic diagnosis.

Lesson 2 • Diagnostic Methodology and Fault Isolation

Introduces structured fault-finding frameworks including symptom analysis, elimination, and substitution methods. A consistent methodology reduces diagnostic time and prevents misdiagnosis.

Lesson 3 • Electrical and Sensor Fault Diagnosis

Traces wiring faults, failed sensors, relay failures, and power supply issues using test instruments and schematics. Electrical diagnosis builds directly on the wiring and measurement skills from Chapter 3.

Lesson 4 • Mechanical Fault Diagnosis

Identifies causes of noise, vibration, misalignment, slow operation, and drive failure through physical inspection. Mechanical faults are often the root cause of apparent electrical symptoms.
