APPLICATION

Qromatic Passive Infrared Occupancy Sensor is
The cost-effective choice for commercial and
Industry installations. All these sensor offer easy
Installation and parameter adjusting. For storage
Areas, small bathrooms, copy rooms, mop/sink
Closets or small spaces without wall switches, the
Ceiling mount sensor SEC3 is your smart choice.

SEC3 uses passive infrared (PIR ) detection
Technology to monitor a room for occupancy
Through a segmented Fresnel lens. This
Specialized lens divides the field of view into
Sensor zones. When a person passes into or out
Of a sensor zone, the sensor detects motion and
Switches its loads ON. The load will remain ON as
Long as there is an occupant moving through the
Sensor zones. A delayed-OFF time adjustment
Prevents the load from switching OFF when the
Space is occupied. In order to keep the lights ON,
A person must pass through a sensor zone at least
Once during the selected delayed-OFF time
Interval. The delayed-OFF time settings can be
Adjusted from 20 seconds (for test mode) to 15
Minutes. When the sensor does not detect motion
During the selected delayed-OFF time, the sensor
Will switch the lights OFF automatically after the
Time interval expires.

SEC3 equipped ambient light detect function. The
Top priority ambient light control function
Maintained the light off when there is ample
Natural sunlight, regardless of occupancy.

Fixed delay off times and ambient LUX levels offer
Consistency status when sensors working
Together, and easy adjustment.
