Ceiling Mount DALI-2 PIR sensor + Light Sensor

DALI PIR and Light Sensor

Ceiling-mounted DALI-2 multisensor. The device includes both a motion sensor and a twilight sensor.

It is also suitable for installation in ceiling structures. The mounting hole diameter is 70–73 mm (the sensor’s outer diameter is 83 mm), and it is installed in the same way as recessed spotlights.

The sensor draws its operating power directly from the DALI bus and therefore does not require an external power source. This means easier and faster wiring and installation.

DALI-2 control requires a DALI-2 master, such as the Iot DALI MASTER.

How do I use the DALI multisensor?

The sensor is installed on the DALI bus just like any other DALI device. See the wiring diagram:

Applications for the DALI sensor

This motion sensor (PIR) is most commonly used to automatically turn lights on and off in closets, storage rooms, and restrooms.

The lights can be programmed to turn on only at dusk. It is ideal for controlling lighting in areas where people only briefly stop by or visit infrequently. By using the sensor, you can ensure that lights do not remain on for months at a time, for example, in a utility room.

For example, you can set the sensor to turn the lights on when it detects motion and turn them off when it no longer detects motion.

You can set the light-off delay and other time delays based on both light level and motion (turn-on and turn-off delays, how long the lights stay on after motion stops, etc.). You can automatically adjust the lighting levels based on the ambient lighting in the room. See the installation instructions included with the product for more details!

Detection Range

Recommended installation height: 2.5 m. The detection range is 130 degrees. Light level detection can be adjusted between 0 and 1,000 lux.

What is DALI?

DALI dimming is a lighting control system that uses a digital protocol for communication between the lighting controller and the lights themselves. This enables precise control of the brightness and color of individual lights or groups of lights, as well as the ability to save and restore pre-programmed lighting scenes. DALI dimming systems typically consist of a DALI controller that sends commands and DALI-compatible luminaires that can receive and respond to these commands.

DALI works best when it is designed and built from the ground up. This is because it requires two control wires running between the devices.

Key Features of the DALI System

• It’s a free protocol! Anyone can use it.
• DALI2 certification requires that devices manufactured by different companies work together. LedStore uses only certified products.
• DALI is fairly easy to implement. You can run power and control wires side by side, since they do not need to be shielded. Thus, 5 wires run throughout the system: L, N, ground, and 2 control wires (5×1.5 MMJ).
• The wires can be installed however you like, as long as they are within 100 meters of the DALI BUS controller. The distance can be even greater if repeaters are used. The recommended maximum length of a DALI network is 300 meters.
• Because DALI uses digital signals for communication instead of analog signals, all devices share the same dimming values. This makes control groups highly functional and precise.
• The system’s addressing scheme (DALI address) ensures that each device or group can be controlled individually.
• A single DALI master can control up to 64 DALI ECD devices.
• A single DALI master can control up to 64 DALI ECG devices.
• A single DALI master can control up to 16 groups.
• A single DALI master can control up to 16 scenes

DALI Terminology

DALI can be challenging for beginners to understand. What do all these terms mean? Here’s a brief overview of the terms

DALI Master

A DALI master is the control center or heart of the system, which typically also includes the DALI bus power supply. The DALI master is the brain of the system, controlling all devices. The master can be programmed and used in various ways, depending on the specific model.

• It can be connected to a computer via USB, and DALI software is installed on the computer.
• The IoT version allows the master to be controlled wirelessly via a smartphone or tablet on the same Wi-Fi network.

DALI Bus

If the DALI Master is the heart of the system, the DALI bus is its artery. It transmits all commands digitally between all devices. The bus is a 2-wire cable that must be connected to EVERY DALI DEVICE! The maximum length of the bus is typically 300 meters. The bus can be extended using repeaters/power supplies or by adding DALI Masters.

DALI Bus Power Supply

This is usually included in the DALI master. Its function is to maintain the bus voltage; the bus carries a 16V current of 100–300 mA, which transmits data.

ECG

ECG stands for Electronic Control Gear, meaning any device that supplies voltage to lights, etc. Examples include DALI transformers and DALI relays. A single DALI master can control up to 64 (OUTPUT) ECG devices.

ECD

ECD stands for Electronic Control Device, meaning a device that controls other devices, such as DALI buttons and DALI sensors. A single DALI master can control up to 64 (INPUT) ECD devices.

Group

In DALI, devices can be organized into groups. A single DALI master can have up to 16 groups, numbered 0–15. The purpose of a group is to reduce the number of DALI signals on the network and simplify operation. When a group receives a command—for example, to dim—all ECD devices belonging to that group dim. The devices in a group therefore behave identically. If you want the devices in a group to be at different levels, this is referred to as a scene.

Scene

In DALI, scenes can be programmed or stored to buttons. A single DALI master can have up to 16 scenes. These are numbered from 0 to 15. The purpose of a scene is to create different lighting modes.

For example, setting the living room spotlight to 50% and the LED strip to 80% with a single command. This simplifies everyday use.

Benefits of DALI Dimming

DALI dimming is an efficient and flexible lighting control technology that offers many advantages over traditional analog dimming systems. Its precision, energy efficiency, scalability, and ability to integrate with other building automation systems make it well-suited for a wide range of applications in commercial, industrial, and residential buildings. Here are the benefits of DALI dimming:

• Precision: DALI dimming enables precise control over the brightness and color of individual lights or groups of lights, which can be particularly useful in commercial, industrial, and residential buildings. This allows for greater control and flexibility in lighting design.
• Energy efficiency: DALI dimming can help reduce energy consumption and lower operating costs, as the brightness and color of lights can be precisely controlled.
• Scalability: DALI dimming systems can be easily expanded to control a large number of lights, making them well-suited for large commercial or industrial projects.
• Integration: DALI dimming systems can be easily integrated with other building automation systems, such as HVAC and security systems, enabling better control and automation of a building’s lighting.
• Flexibility: DALI dimming offers a wide range of options for controlling lights, ranging from simple on/off switching to more advanced control options, such as setting and resetting pre-programmed lighting scenes.
• Common Standard: It ensures that devices from different manufacturers always function the same way when connected together. You can also replace existing components with newer and better ones whenever they become available.
.
• Easy to install: Thanks to DALI fiber-optic technology, you don’t need to divide lights into zones or keep track of wiring. The DALI system uses two connected wires. These wires control all devices. Installers don’t have to keep track of everything because they don’t need to know how the lights will ultimately be installed.
• Easy to change: You can make changes to the settings quickly. After a while, you might want to replace the lights and get something nicer. With the centralized software, you can easily change lighting profiles.
