• Thermal imaging sensor
• Light level sensor
• Temperature and humidity sensor
• Acoustic sensor
• TVOC sensor
• RESET button

Button Functions:

• Radio Network Button: Short press (< 0.5s) to associate/open/close a network. Long press (> 5s) for radio reset.
• Connection Button: Short press (< 0.5s) for network creation/initial connection. Long press (> 5s) for target connection.
• Reset Button: Short press (< 0.5s) for reset. Long press (> 5s) for factory reset.

7. Mounting

Mounting and wiring must be performed without power. Follow safety instructions carefully.

Diagrams illustrating the mounting steps.

8. Wiring

Diagrams showing wiring for different load types (dimmable and non-dimmable).

Note: The relay is dedicated to powering the ECG to reduce energy consumption. ECG shutdown is delayed by 5 minutes.

The detector is configured for dimmable DALI ECGs but can be paired with DALI (ON/OFF) actuators. Use the "Legrand CLOSE UP" app to change the load type to "Non-Dimmable".

Master/Slave Configuration:

By default, the device is configured as Master. For Slave configuration, refer to the LIGHT UP Technical Guide. A Master can be paired with up to 5 Slave detectors.

Important:

• The detector powers the DALI BUS. Do not connect 2 sensors to the same DALI BUS.
• Slaves can extend the detection area. No load should be paired with a Slave.
• If used in Master/Slave mode, the wired button must be connected only to the Master sensor.

9. Detection Zone

Diagrams illustrating the detection zone coverage and possibilities for monitoring up to 6 zones of interest and/or exclusion.

10. Installation

Maximum installation height is 4 m. Ensure the device's field of view is not obstructed by objects that could hide people. Avoid direct airflow on the device.

Diagrams showing correct and incorrect installation scenarios.

11. First Commissioning

The device is ready for use after 5 minutes of operation and self-calibrates within 20 minutes. Immediate calibration can be initiated via the CLOSE UP app, ensuring no one is in the detection area.
