CAUTION
Turn power OFF at circuit breaker before connecting Power
Pack or Sensor.
Do NOT touch the window of infrared sensor on the PCB
assembly.
FCC ID: NRIOS-361DT
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1)This device may not cause harmful interference,
(2)This device must accept any interference received,
Including interference that may cause undesired operation.
OVERVIEW
The OS-361DT is a ceiling mount low voltage dual technology
occupancy sensor designed for area lighting, or HVAC
control, for energy efficient building management. The sensor
combines a Passive Infrared (PIR) sensor, a High Frequency
Doppler (HFD) sensor and advanced signal processing
firmware to perform superior occupancy sensing capability.
An
omni-directional
state-of-the-art HFD sensor and advanced signal processing
firmware are employed to provide superior occupancy
sensing capability. The sensor will activate the relay output
and delay timer when both PIR and HFD sensors detect the
presence of occupant. The delay timer will be reset if either
PIR or HFD sensor detects motion before the delay time has
elapsed.
The OS-361DT is ideal for areas where motion may not be
easily detectable by a single technology occupancy sensor.
The sensor is operated by 24VDC low voltage power supplied
from an IR-TEC power pack, or building management system.
The sensor provides a form A relay dry contact for control of
lighting and/or HVAC systems.

APPLICATION NOTES
PIR sensor is more sensitive to the movements
1.
"crossing" the detection zones than "toward" or "away"
the sensor unit. Avoid placing the sensor in line with the
path of occupant, if possible.
2.
PIR sensor cannot "see" the movements behind
obstacles, such as furniture, shelf, glass or partitions. As
a
a general rule, ensure to place the sensor at where the
occupant could have clear view of the sensor.
3.
HFD sensor may penetrate through certain types
of
non-metallic
partition
plywood...etc) and detects the movements outside of
partition. Adjusting the HFD sensitivity may be necessary
to achieve optimal detection.
Place the sensor at least at 5 ft. (1.5m) away from air
4.
supply duct and fluorescent lighting to avoid false
activating.
5.
For open office areas with partition which could block the
sensor view to occupant movements, it is recommended
to place the sensors over the intersection of multiple
workstations. For large areas of open office or space,
place multiple sensors so that there is overlap coverage
with each adjacent sensor.
6.
The OS-361DT can be either surface mounted or recess
mounted in a hole with 3.4" diameter on the ceiling.
