Philips DUS804C, DUS804C-SM Installation Manual

DUS804C & DUS804C-SM

Ceiling Mount Universal Sensor Installation Manual

The DUS804C and DUS804C-SM are low profile recessed flush mount 360º ceiling mount sensors that
combine motion detection (PIR), infra red remote control reception (IR) and ambient light level detection
(PE) in the one device.
In applications such as office buildings, lecture theatres, and homes, the DUS804C and DUS804C-SM
universal sensors can be utilised to detect different levels of motion and switch on the lights. In the case of
the standard detection model it can detect movements of items of a size of 700mm x 250mm, whereas the
slight motion version can detect movements of items of a size of 200mm x 200mm – it also has more
detection zones and a faster detection speed (0.5ms vs 1.0ms) – see specifications on page 4 for more
information.
When rooms are unoccupied, 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. The same sensor provides IR control reception to enable full remote
control over lights, audio-visual equipment and blinds. A range of hand held infra-red transmitters to
complement DUS804 and DUS804C-SM universal sensors are available. 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 facilitates light compensation. Both the DUS804C and DUS804C-SM can
also be placed in an automatic “Daylight Harvesting” mode once motion has been detected for additional
energy savings.

2 DUS804C Installation Manual Rev I.docx

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 NETWORK CONNECTIONS

:

• 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 and heating/cooling sources

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

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

• When terminated correctly and powered from the Dynet network the sensors LED will flash for 5 min every time a push

button is pressed. This is to confirm the sensor is terminated correctly

• Only after all network devices are confirmed to be terminated correctly can the commissioning of the system begin.
