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 quad element PIR sensor, a
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.

PIR sensor is more sensitive to the movements
“crossing” the detection zones than “toward” or “away”
the sensor unit. Avoid placing the sensor in line with the
path of occupant, if possible.
PIR sensor cannot “see” the movements behind
obstacles, such as furniture, shelf, glass or partitions. As
a general rule, ensure to place the sensor at where the
occupant could have clear view of the sensor.
HFD sensor may penetrate through certain types
of non-metallic partition material (glass, plaster,
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
supply duct and fluorescent lighting to avoid false
activating.
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.
The OS-361DT can be either surface mounted or recess
mounted in a hole with 3.4” diameter on the ceiling.

The OS-361DT is an occupancy sensor which combines two
different sensing technologies, PIR and HFD, in one housing
for ceiling mount installation. The sensor is operated by 24
VDC low voltage power. Whenever the sensor detects the
presence of occupant, its dry contact relay output will be
engaged for the delay time programmed. The delay timer will
be reset if any motion is detected by either PIR or HFD sensor
before delay time elapses.
8 different delay times and 4 different HFD sensitivity levels
can be programmed via specific DIP switch combinations.
2 LED’s are available to indicate the operation of PIR and
HFD sensors respectively. The sensor operation LED can be
disabled by specific DIP switch, if necessary.
It is recommended to conduct a walk test to verify optimum
coverage after sensor installed. To test the sensor range,
restore the front cover, apply the low voltage power and wait
approximately 90 seconds for sensor to warm up. The LED
will blink during warm-up period. Walk into the projected area
in the path of occupant show up and observe if the sensor
can detect the presence. The LED will be lit whenever sensor
detects the motion. If the space has multiple entrances,
repeat the test in all available paths.
HFD sensor could possibly detect the movements outside of
certain type of dry wall or partition. If happened, sensitivity
can be adjusted by changing the ON-OFF combinations of
DIP switch #1 and #2 as the following table shows.
2 LED’s are available to indicate the status of PIR and HFD
sensor operation. The LED indication can be disabled by
setting the SW #3 to OFF position.
A 6-pole DIP switch is available for various sensor settings via
combinations of ON and OFF positions of specific switch.
Various control modes may be achieved by different wiring
connections. The following diagrams are typical control for
reference. For the availability of more complex control, please
contact [email protected] for technical assistance.
