Full title and description

St IEC 62386-303-2024 — Digital addressable lighting interface (DALI) — Part 303: Particular requirements — Input devices — Occupancy sensor (IEC 62386-303:2017 with Amendment 1:2024, consolidated). This publication contains the 2017 base part together with the 2024 amendment that updates requirements, reports and behaviour definitions for DALI input devices that provide occupancy/presence information to lighting control systems.

Abstract

IEC 62386-303:2017/AMD1:2024 defines the particular requirements, object types and behaviour for DALI input devices that detect presence or movement (occupancy sensors). The amendment clarifies data objects, reporting modes, commissioning behaviour and test/verification criteria to improve interoperability of occupancy sensors within DALI (Digital Addressable Lighting Interface) systems and align device behaviour with more recent container parts of the IEC 62386 series.

Scope

This part of IEC 62386 applies to input devices that provide occupancy or presence information to a DALI lighting-control system by means of movement or presence sensing functions. The amendment (A1:2024) updates and clarifies the particular requirements for occupancy sensors. The document is applicable only to input devices that comply with the general requirements given in IEC 62386-103 (device description and common object types).

Key topics and requirements

• Definitions and classification of occupancy sensor device types and their DALI object mappings (object types and behaviour for reporting presence/movement).
• Signal/reporting modes: event reporting, automatic reporting, polling responses and message timing/format expectations for presence detection.
• Commissioning and configuration details required for interoperable operation within DALI systems, including startup behaviour and default settings.
• Requirements for measurement output (binary presence, movement events, temporal filtering, occupancy state durations) and state transition semantics.
• Test and verification criteria for functional behaviour and conformance to DALI messaging rules (interoperability and conformity checks).
• Normative references and dependencies on other IEC 62386 parts (notably Part 101/103 and related input-device parts) for electrical, communication and object definitions.
• Updates introduced by Amendment 1: clarifications to object definitions, additional reporting scenarios and alignment with newer sensor-related parts of the IEC 62386 series.

Typical use and users

Primary users include occupancy-sensor and lighting-control manufacturers, system integrators, lighting designers, test laboratories and certification bodies involved in DALI/DALI-2 product compliance. The standard is used when specifying sensor behaviour for commercial and institutional lighting projects, for product design and firmware development, for interoperability testing and for preparing product declarations used in procurement.

Related standards

IEC 62386 is a multipart standard — related parts commonly referenced with Part 303 include: IEC 62386-101 (general requirements), IEC 62386-103 (device description and common object types), IEC 62386-304 (light sensors), IEC 62386-305 (colour sensors), IEC 62386-306 (multi-purpose sensors), and other device-specific parts (e.g., control devices and energy reporting parts). The DALI-2 certification framework and associated test documents reference these parts for product certification.

FAQ

Q: What is this standard?

A: It is IEC 62386-303 (Part 303) with Amendment 1:2024 — the DALI specification for occupancy (presence/movement) input devices that defines particular requirements and behaviour for occupancy sensors in digital lighting-control systems.

Q: What does it cover?

A: It covers definitions, required object mappings, reporting modes, commissioning behaviour and test/verification criteria for occupancy sensors that communicate over the DALI protocol. The 2024 amendment clarifies and extends several behaviours and reporting scenarios to improve device interoperability.

Q: Who typically uses it?

A: Manufacturers of occupancy sensors, lighting-control system designers, integrators, test labs and certification bodies, and specifiers writing product or procurement requirements for DALI-based lighting systems.

Q: Is it current or superseded?

A: This publication is an amendment to the original 2017 Part 303 and was published in 2024 as Amendment 1. As of the 2024 consolidated edition it is the current amended text for Part 303. Users should verify whether any later amendments or new editions have been published after April 10, 2024 when making long-term compliance or procurement decisions.

Q: Is it part of a series?

A: Yes — IEC 62386 is a multipart international standard for the Digital Addressable Lighting Interface (DALI). Part 303 addresses occupancy sensors specifically; other parts cover control gear, control devices, light sensors, multi‑purpose sensors and common definitions used across the DALI ecosystem.

Q: What are the key keywords?

A: DALI, occupancy sensor, presence, movement detection, input device, IEC 62386-303, amendment 2024, DALI-2, interoperability, commissioning.
