Definition
Lighting protocol (Digital Addressable Lighting Interface). Integrable in KNX via a DALI Gateway. Allows individual control of up to 64 DALI ballasts per DALI bus.
Questions using this term
- DALI devices can be commissioned through the KNX/DALI gateway, typically using ETS apps or manufacturer-specific tools.5. Lighting Control · Beleuchtung & Beschattung
- DALI-2 (IEC 62386 Edition 2, 2014+) is the major evolution of DALI v1, adding native support for input devices (sensors, push-buttons) directly on the DALI bus itself, together with a product certification programme administered by the DALI Alliance (DiiA).1. Architecture · DALI vs DALI-2
- The DALI bus uses a polarity-free twisted pair (no + / - orientation), with Manchester coding at 1 200 baud over a nominal 22.5 V DC supply, and is allowed to share the same multi-core cable as the 230 V mains feeding the luminaires.1. Architecture · Physikalische Schicht
- Self-contained emergency luminaires (DT1) under DALI-2 support standardised commands for the monthly function tests and annual duration tests required by EN 50172, and these tests can be automated from a central DALI-2 controller.2. Devices · Typ 1 Notbeleuchtung
- DALI-2 supports several application controllers active on the same bus (multi-master), with an arbitration mechanism that prevents conflicts when two controllers try to command the same control gear at the same time.4. Application Controllers · Multi-Master
