conflict with each other, and may require use of multiple sensors.

Motion detection installation steps
•
An ultrasonic sensor should never be located within 17.5 meters of another ultrasonic sensor.
•
Chose a location where it may face doorways etc which could cause false triggering.
•
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. Sensor should be at least 2.5m from horizontal or
vertical air ducts
•
Position the sensor where pedestrian traffic is likely to walk across the detection zones
•
Fix the sensor to a firm section of ceiling. Sensor can be surface mounted using ring provided.
•
Note that for the DUS804C-UP coverage area is rectangular (see Motion Detector coverage diagram)
•
When terminated and power there are three indicating LED‟s for the following information
o
Blue = Low network voltage. The sensor must receive minimum of 12VDC from the Dynet network. If
the right network voltage is not present at the sensor terminals when the whole system is powered,
then additional network power supplies (DDNP1501) will be required.
o
Green = Ultrasonic detection activity
o
Red = PIR detection activity
• When terminated correctly and powered from the Dynet network the sensors LED‟s will flash for 5 min every time a
Dynet push button is pressed. This is so the installer can confirm the sensor is terminated correctly with other network
devices.
• Only after all network devices are confirmed to be terminated correctly can the commissioning of the system begin.
