Modern AGL is no longer just lamps and cable — LED fixtures, smart controllers, remote monitoring platforms, networked equipment and airport-connected systems all carry sensing, communication, control, diagnostic and data functions that conventional electrical/functional commissioning does not exercise. Division 24 verifies the complete advanced-technology layer: LED system and thermal performance, smart AGL validation, intelligent and remote monitoring, remote diagnostics, digital control, smart sensors, networked equipment, data communication, cybersecurity where applicable, user access, communication security, backup arrangements, automation, and emerging airport technology.
Fundamental Principle: advanced AGL systems shall not be considered commissioned merely because the physical equipment operates — their sensing, communication, control, diagnostics, data integrity, access control and intelligent functions shall also be verified where those functions are provided. Divisions 01–23 cover conventional pre-commissioning, electrical, functional and system-level commissioning; Division 24 is the dedicated advanced/technology-forward layer, not a duplicate of that scope.
Division 24 runs after conventional commissioning is complete, carrying each LED/smart asset through physical, electrical, control, communication and intelligence verification before integrated acceptance.
For an intelligent LED AGL asset, the commissioning record should be capable of following the complete chain — a failure can occur at the physical, electrical, control, communication or software/interface level.
| Link | What It Confirms |
|---|---|
| AGL Fixture | The physical fixture is correctly identified, rated and installed |
| LED Module | LED module type, rating and optical performance are verified |
| Driver | Driver identification, input supply and operation are verified |
| Isolation Transformer | The feeding transformer is verified under Division 04 |
| CCR / Series Circuit | Circuit and CCR association is correctly traced |
| Controller | Local controller identification and operation are verified |
| Network | Network connection, addressing and communication are confirmed |
| PLC / Gateway | Data exchange through the PLC/gateway is verified |
| ALCMS / SCADA | The central system correctly represents the actual field condition |
| HMI / Operator | The operator interface displays the correct status |
| Monitoring | Intelligent monitoring output matches the actual field condition |
| Alarm / Diagnostic | Alarm generation and diagnostic response are verified |
| Event Log | The event is correctly recorded with time/date information |
| Maintenance Response | The resulting maintenance response and closure are confirmed |
Because a failure in a smart AGL asset can occur at several different levels, Division 24 classifies failures separately from conventional divisions.
| Class | Examples |
|---|---|
| A — Physical Failure | LED fixture failure, driver failure, sensor failure, cable failure |
| B — Electrical Failure | Incorrect voltage, current abnormality, insulation failure, power-supply failure |
| C — Control Failure | Incorrect command, incorrect intensity, switching failure, interlock failure |
| D — Communication Failure | Network loss, device communication loss, incorrect data, delayed feedback |
| E — Monitoring Failure | Incorrect status, missing alarm, false alarm, incorrect diagnostic |
| F — Cybersecurity/Access Failure | Unauthorized access, incorrect user privilege, authentication failure, security-control failure — where applicable |
Two conditions should be established before advanced commissioning of any LED, smart or networked AGL asset begins.
Grouped by advanced-commissioning focus — click any topic to expand its verification checks and acceptance criteria.
Acceptance Criteria: fixture identity, rating, driver, and installed configuration match the approved design, and all documented fields are recorded before performance testing begins.
Acceptance Criteria: measured light output, intensity, beam distribution and colour meet the specified performance, and switching/intensity-step response and operating stability are confirmed correct.
Hold Point: thermal verification uses the manufacturer/project-defined limits rather than an arbitrary universal temperature limit.
Acceptance Criteria: each interface in the field equipment → sensor/controller → network → monitoring platform → operator interface chain is individually verified before the smart system is accepted.
Acceptance Criteria: monitoring system output matches the actual field condition for every tested condition.
Hold Point: any discrepancy between the actual field condition and the displayed remote condition is investigated and documented before acceptance.
Acceptance Criteria: the diagnostic system correctly detects, identifies, indicates, records and reports recovery for every simulated fault condition.
Hold Point: a command is not accepted as successful merely because it was sent — field response and feedback must confirm correct status.
Acceptance Criteria: each sensor's measurement accuracy, alarm threshold and status/failure indication are verified as specified.
Acceptance Criteria: equipment correctly rejoins the network and resumes correct communication after interruption, device restart, or network recovery testing.
Acceptance Criteria: data integrity is confirmed at every applicable stage from field equipment through to the HMI.
Hold Point: this is performed against the airport/operator's approved cybersecurity requirements and project specifications — a generic cybersecurity checklist is not a substitute for the airport's actual cybersecurity requirements.
Acceptance Criteria: each user account holds only the access level necessary for its assigned role, and disabled/removed accounts are confirmed closed.
Acceptance Criteria: authorized communication paths, segmentation and device authentication are verified, with security requirement, method, result and evidence recorded for each.
Acceptance Criteria: Backup Created → Backup Verified → Restoration Tested Where Required is confirmed complete for every applicable system.
Acceptance Criteria: this is recorded as an evaluation activity — not treated as a mandatory acceptance requirement unless the project specification requires it.
Acceptance Criteria: automation response, alarm, equipment response, operator indication, event logging and recovery are each individually verified for every tested automated function.
Advanced systems are evaluated across five layers before Division 24 is closed for a given asset — every layer has to hold.
Is the equipment correctly installed?
Does the equipment operate electrically as specified?
Does the equipment respond correctly to commands?
Does information move correctly between systems?
Does the monitoring/diagnostic/automation function correctly interpret and respond to the condition?
Quick answers about Division 24 — Advanced Commissioning in the AGL Testing & Commissioning Manual.
Division 24 of the AGL Testing & Commissioning Manual covers Advanced Commissioning. Modern AGL is no longer just lamps and cable — LED fixtures, smart controllers, remote monitoring platforms, networked equipment and airport-connected systems all carry sensing, communication, control, diagnostic and data functions that conventional electrical/functional commissioning does not exercise. Division 24 verifies the complete advanced-technology layer: LED system and thermal performance, smart AGL validation, intelligent and remote monitoring, remote diagnostics, digital control, smart sensors, networked equipment, data communication, cybersecurity where applicable, user access, communication security, backup arrangements, automation, and emerging airport technology. It contains 17 topics (TC-ADV-001 to TC-ADV-017) organised into 7 groups (A–G), each topic with its own verification checks.
Fundamental Principle: advanced AGL systems shall not be considered commissioned merely because the physical equipment operates — their sensing, communication, control, diagnostics, data integrity, access control and intelligent functions shall also be verified where those functions are provided. Divisions 01–23 cover conventional pre-commissioning, electrical, functional and system-level commissioning; Division 24 is the dedicated advanced/technology-forward layer, not a duplicate of that scope.
Division 24 runs after conventional commissioning is complete, carrying each LED/smart asset through physical, electrical, control, communication and intelligence verification before integrated acceptance. Steps: LED/Smart Install → Physical Verify → Electrical Verify → LED Performance → Sensor Verify → Digital Control → Network Comms → Remote Monitoring → Remote Diagnostics → Alarm & Event → User Access → Cybersecurity → Backup & Restore → Automation → Integrated Validation → Acceptance. Focus areas: LED performance & thermal behaviour; Smart monitoring & diagnostics; Digital control & smart sensors; Network & data communication; Cybersecurity, access & backup.

For an intelligent LED AGL asset, the commissioning record should be capable of following the complete chain — a failure can occur at the physical, electrical, control, communication or software/interface level. AGL Fixture: The physical fixture is correctly identified, rated and installed; LED Module: LED module type, rating and optical performance are verified; Driver: Driver identification, input supply and operation are verified; Isolation Transformer: The feeding transformer is verified under Division 04; CCR / Series Circuit: Circuit and CCR association is correctly traced; Controller: Local controller identification and operation are verified; Network: Network connection, addressing and communication are confirmed; PLC / Gateway: Data exchange through the PLC/gateway is verified; ALCMS / SCADA: The central system correctly represents the actual field condition; HMI / Operator: The operator interface displays the correct status; Monitoring: Intelligent monitoring output matches the actual field condition; Alarm / Diagnostic: Alarm generation and diagnostic response are verified; Event Log: The event is correctly recorded with time/date information; Maintenance Response: The resulting maintenance response and closure are confirmed.
Because a failure in a smart AGL asset can occur at several different levels, Division 24 classifies failures separately from conventional divisions. A — Physical Failure: LED fixture failure, driver failure, sensor failure, cable failure; B — Electrical Failure: Incorrect voltage, current abnormality, insulation failure, power-supply failure; C — Control Failure: Incorrect command, incorrect intensity, switching failure, interlock failure; D — Communication Failure: Network loss, device communication loss, incorrect data, delayed feedback; E — Monitoring Failure: Incorrect status, missing alarm, false alarm, incorrect diagnostic; F — Cybersecurity/Access Failure: Unauthorized access, incorrect user privilege, authentication failure, security-control failure — where applicable.
Two conditions should be established before advanced commissioning of any LED, smart or networked AGL asset begins. Numerical & Threshold Limits Are Not Universal: LED thermal verification uses the manufacturer/project-defined limits, not an arbitrary universal temperature limit; Sensor measurement accuracy and alarm thresholds are project- and equipment-specific, taken from the applicable datasheet; Cybersecurity checks are performed against the airport/operator's approved cybersecurity requirements and project specifications — a generic checklist is not a substitute for the airport's actual requirements; Future technology evaluation is an evaluation activity, not necessarily an acceptance requirement for every project.
Division boundary: Divisions 01–23 cover pre-commissioning, core electrical equipment, fixture/functional commissioning, photometric verification, FAT/SAT, system integration, performance acceptance, troubleshooting, documentation and handover; Division 24 is the dedicated advanced/technology-forward layer for LED, smart, networked and airport-connected AGL systems — it does not duplicate conventional commissioning already covered elsewhere; A command is never accepted as successful merely because it was sent — field response and feedback must confirm correct status; No advanced AGL asset is released until every applicable item in this division is closed, in addition to its conventional commissioning divisions.
Advanced systems are evaluated across five layers before Division 24 is closed for a given asset — every layer has to hold. (1) Physical — Is the equipment correctly installed?; (2) Electrical — Does the equipment operate electrically as specified?; (3) Control — Does the equipment respond correctly to commands?; (4) Communication — Does information move correctly between systems?; (5) Intelligence — Does the monitoring/diagnostic/automation function correctly interpret and respond to the condition?
Advanced commissioning scenarios are where standard procedures meet non-standard conditions.
Build the technical knowledge to understand complex system interactions, edge-case decision-making, and how experienced commissioning engineers reason through situations the standard checklist doesn't fully cover.
