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.

- Page 3 The DUS804C-DALI has a built in pull up mask that can be rotated to remove 120 scanning 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.
