Legrand DALI Light Up Multi-Sensor: Advanced 3-Zone Occupancy and Environmental Sensing

The Legrand DALI Light Up multi-sensor is an advanced device designed for lighting control and building management applications. It integrates multiple sensors to provide comprehensive environmental data and occupancy detection.

Product Overview

This multi-sensor unit offers advanced features including:

3-Zone DALI Lighting Control: Manages three lighting zones, supporting group dimming and ON/OFF functions.
Occupancy and Presence Detection: Utilizes thermal imaging sensors to measure people count per zone and detect presence.
Environmental Sensing: Includes sensors for ambient light, temperature, relative humidity, acoustic level, and VOC (Volatile Organic Compounds) for air quality assessment (eCO2 estimation).
Connectivity: Features Bluetooth 5.0 for commissioning via the 'CLOSE UP' mobile app and a 2.4 GHz radio frequency for network management.
Auxiliary Inputs: Supports an auxiliary input for lighting control via a wired push-button.
DALI Output: Provides DALI bus power and control for diffuse lighting.
Relay Output: Dedicated for powering DALI ECGs.

Installation and Wiring

Mounting: Designed for recessed installation with a 68mm diameter cutout. Surface mounting is possible with accessory Art. 0 485 80.
Safety: Installation and wiring must be performed without power. Follow safety instructions carefully.
Wiring: The device supports DALI bus power and control. Wiring diagrams are provided for both dimmable and non-dimmable loads. The relay output is dedicated to powering DALI ECGs, with a 5-minute delay for extinguishing.
Master/Slave Configuration: The device defaults to Master mode. It can be configured as a Slave to extend detection areas, supporting up to 5 Slave devices per Master.

Using the 'CLOSE UP' Mobile App

Commissioning: The 'CLOSE UP' app (available for iOS and Android) is used for device setup, configuration, and advanced parameter adjustments.
Features: The app allows for sensor calibration, zone creation (interest and exclusion zones), and monitoring of device status.
Zone Creation: Users can define up to 6 interest zones and 6 exclusion zones. It is recommended to maintain a distance from obstacles when defining zone coordinates.
Calibration: The device self-calibrates within 20 minutes of operation. Manual calibration can be initiated via the app.
Advanced Settings: The app provides access to advanced sensor settings, including offsets and reset functions.
