DUS804C-DALI

Ceiling Mount Universal Sensor Installation Manual

The DUS804C-DALI is a low profile recessed flush mount 360º ceiling mount sensors that combines

motion detection (PIR) and ambient light level detection (PE) in one device. The sensor is powered directly

by the DALI network that is running between the DALI fittings, eliminating the need for additional network

field wiring or network power cables. The sensor can only be used when connected to the DALI port of the

DDBC120-DALI unit.

In applications such as office buildings, lecture theatres, and homes, the DUS804C-DALI multi function

sensor can be utilised to detect different levels of motion and switch on the lights. The sensor can detect

movements over a 7.42m x 5.66m area with a mounting height of 2.4m. When an area is unoccupied the

sensor can detect this and the lights can be automatically dimmed or switched off to provide energy

savings. The unit also incorporates a segmented click-up bezel surrounding the motion sensor element.

This enables a portion of the sensing field to be readily masked to prevent nuisance detection from

adjacent doorways or corridors. In situations where it is critical to maintain precise lighting control for

individual workspaces, such as an office workstation or even air traffic control centers, the DUS804C-DALI

facilitates light compensation. The DUS804C-DALI can also be placed in an automatic “Daylight

Regulation” mode for additional energy savings.

This unit is for indoor use only. This unit is designed for installation in a 64mm diameter hole where the

ceiling void is at least 40mm deep. Select an appropriate indoor mounting location, as detailed in the location

guidelines on the following pages. Note that the product has two functions, and the optimum mounting

location for each individual function may conflict with each other, and may require use of multiple sensors.

DUS804C-DALI network connections

Motion detection mounting location

•Power down & isolate DALI bus prior to wiring the device

•Fix the sensor to a firm section of ceiling

•Position the sensor so it is between 2.1 and 4.0m from the floor. Optimum height is 2.4m

•Position the sensor so it is at least 1m away from electrical lighting such as neon and fluorescent lights

•Position the sensor as to avoid exposing it to direct sunlight, glare and heating/cooling sources

•Position the sensor where pedestrian traffic is likely to walk across the detection zones (see motion

detection coverage diagram)

•Note that for the DUS804C-DALI coverage area is rectangular (see Motion Detector coverage diagram)

•For programming instructions refer to Dynalite Tech Note - Setting up Motion Detector function

DALI cable connected to sensor.

The sensor has been designed for the DALI network to loop through and then loop out to the next device.

The different DALI network devices can be connected in any order along the network. The sensor does not

need to be directly connected to the lighting groups that is to be controlled.

photo electric cell mounting location

Position the sensor so it “sees” a combination of artificial light and

natural light indirectly.

Position the sensor so it is not directly exposed to artificial light or

sunlight and glare.

Ensure that the sensor is directed onto working surfaces were

correct light level is required.

masking regions from motion detection

The DUS804C-DALI has a built in pull up mask that can be rotated to remove 120oscanning range from the sensor. This feature can be

used in situation when a section of the motion detection zone needs to be blocked out. When mounting the sensors in a single office the

mask can be used to block out motion that would be detected in the corridor causing false triggering of the sensor and then turning on

the lighting unnecessary. This feature does not affect the light level detection functionality of the sensor.
