Legrand PIR+US Ceiling Mount Sensors (DALI)

1. Use

The DALI sensor Cat. No. 0 489 35 is a device that measures the daylight level and detects the presence of people using dual technology (passive infrared and ultrasonic - PIR + US).

It can be surface-mounted on a concrete ceiling using box Cat. No. 0 488 75, or flush-mounted directly in a suspended ceiling using claws or in a flush-mounting box Cat. No. 0 800 31.

It is suitable for indoor workspaces such as offices, meeting rooms, classrooms, etc., and it can be used on its own or in combination with DALI power supply/wiring unit Cat No. 0 488 76.

This sensor can manage up to 2 groups of dimmer ECGs, "window" and "corridor" type (containing a maximum of 64 ECGs), for which it is possible to configure an offset light level.

If it is used in combination with DALI power supply/wiring unit Cat No. 0 488 76, it can manage up to three ECG groups (64 ECGs max). These groups are made up as follows: 2 "window" and "corridor" groups which can be used to dim the lighting, for which it is possible to set a light level offset, and a "display board" group which can only be switched ON/OFF.

This sensor is fully configured using configuration tool Cat. No. 0 882 30/BMSO4001, with which it is possible to:

• Distribute DALI ECG addresses
• Pair DALI ECGs with their sensor and their group (window, corridor or display board)
• Define the light level offset between the "window" group and the "corridor" group
• Designate Master and Slave sensors
• Define the standby level when there is no detection
• Define the standby time
• Configure all the other sensor settings (for example, daylight setpoint, time the lighting remains on after detection, choice of detection technology, operating mode, etc.)

The DALI sensor Cat. No. 0 489 35 is powered with 16 VDC by the DALI bus. A DALI power supply Cat No. 0 035 15 or 0 035 13 can supply this voltage to the DALI BUS with a maximum of 200 mA, and the DALI unit Cat No. 0 488 76 also acts as the bus power supply.

7. Settings

7.1 Detection settings

The sensor's detection behavior can be configured through various settings:

Time delay: Length of time the load is on after detection.

Pulse mode (= push-button mode): If the time delay is set to 0, the sensor is in push-button mode. In this case, there is a 10-minute time delay before the load is switched off. If the setting is overridden or there is a new detection, the 10-minute time delay starts again. Possible with configuration tool 0 882 30/BMSO4001.

Sensitivity: Detection range setting.

7.1 Detection settings (continued)

Auto on/Auto off mode: The lighting switches on automatically on detection of presence if the natural light level is insufficient. The lighting switches off automatically when no presence is detected and at the end of the time delay set, or if the natural light level is sufficient (regulation activated). Another detection causes automatic switch-on if there is insufficient light.

Walkthrough mode: If no presence is detected in the 20 seconds following an initial detection, the device will switch off the load after 3 minutes. If another movement is detected within the 3 minutes following initial detection, the device will switch off the load at the end of the set time delay.

Manual on/Auto off mode: The lighting is switched on via a manual control but switches off automatically when no presence is detected and at the end of the time delay set. After switch-off, if another movement is detected within a 30-second period, the lighting switches on automatically (Restart function must be enabled). After 30 seconds, the lighting has to be switched on manually.

Detection system:

• Initial detection: The load is switched on as soon as the first detection occurs if the natural light level is below the light level threshold.
• Maintain: The load remains active if another presence is detected.
• Restart: In manual mode. After switch-off, any new detection within a 30-second period triggers an automatic switch-on. After 30 seconds, the device must be switched on manually. Possible in Manual on/Auto off mode only.
• Alarm: An audible signal is emitted before switch-off (1 minute before, then 30 seconds, then 10 seconds).

7.2 Light level settings

Daylight setpoint: Value at which the load comes on if the natural light level is less than the setting.

Eye function: Value 0 (eye on configuration tool 0 882 30/BMSO4001) is used to save the ambient light level in the room as a daylight setpoint.

7.2 Light level settings (continued)

Advanced mode:

• Calibration: The ambient light level measured with a luxmeter must then be transmitted to the sensor.
• Regulation: Automatic switch-off of the load 10 minutes after the daylight setpoint is exceeded with an additional safety threshold (to avoid lights switching off at the wrong moment).
• Light contribution: Quantity of additional lux provided by the load being switched on. When the light contribution parameter is set to "Auto" on configuration tool Cat. No. 0 882 30/BMSO4001, the sensor automatically calculates how much light is provided.

Offset function: Luminaires controlled according to the daylight level. Used to manage an increased light contribution on the "corridor group" and thus obtain an even light level in the classroom. This setting consists of entering a value (% of desired difference in light level) using tool 0 882 30/BMSO4001. See the DALI product programming manual.

Example of 30% offset Diagram Description: Shows a room with three lighting groups: "Window group" (10%), "Corridor group" (unspecified), and "Display board group" (40%).

Master/Slave parameter setting: By default, all the sensors are supplied as Slaves, but to manage lighting they must be configured as the Master. When configured as the Master, the sensor manages presence and lighting regulation. When configured as a Slave, the sensor only manages presence.

7.3 Modifying the settings using the configuration tool

0 882 40: Configuration gateway and Legrand Close Up application. The Close Up application is available on the Apple Store [App Store] and the Play Store [Google Play]. The detector functions are controlled by a number of parameters which can be changed or programmed by an infrared configurator. In combination with configuration tool 0 882 40, the Legrand Close Up smartphone app can be used to view and modify all the detector parameters with online help. Point the infrared configuration tool at the detector and send the necessary programming commands to the unit as indicated in the table below. For more information about setting parameters, refer to the data sheet for the configuration gateway Cat. No. 0 882 40.

0 882 30/BMSO4001: configuration tool When the sensor receives an IR command via the configuration tool, a red LED lights up acknowledging the modification. For more information about setting parameters, refer to the data sheet for the configuration tool Cat. No. 0 882 30. Note: As from 01/01/2022, product ref. 0 882 30 is no longer sold.
