Light regulation positioning
When positioning sensors, there are two methods of light regulation to consider:
(speak to design engineer if unsure):
•
If the sensor is used for Closed loop sensing, then position the sensor so it sees a mixture of indoor and
outdoor light.
•
If the sensor is used for Open loop sensing, then position the sensor so it sees the light level from one
light source such as daylight, to adjust light levels elsewhere.
Closed loop light regulation
Testing using the inbuilt indicator LED.
When first connected and powered from the network the red indicator LED on the sensor will flash for 3 minutes
when it receives a button message. This allows the installer to confirm that the sensor is terminated correctly and
communicates with other networked devices.
Indicator LED:
Red = PIR motion detection (All sensors).
Green = Ultrasonic motion detection (DUS804CS-UP).
Blue = Low network voltage (DUS804CS-UP)
