It’s commonly known Microwave and Infrared are main detecting technologies in lighting controls. Both have the advantage and
disadvantage for industrial applications.
The remedy is to create Dual Sense by combining both technologies to make use of the advantage and bypass the disadvantage.
* sensitive to minor motion.
* sensitive to radial movement.
* can be reflected by objects hence covering big detection area
* resilient to heat source, smoke and and air conditioner.
* penetrates walls, picks up motions outside of the office area;
* back wave detection, false trigger by motions at the back.
* can be false triggered by ventilation fans, water pipe, elevators
etc. in industrial application.
* no penetration, confined detection area.
* sensitive to tangential movement.
* resilient to motion object which has no heat radiation.
* can be false triggered by air conditioner, smoke and
other heat sources.

Advantage
Disadvantage
Disadvantage
Advantage
* HF: Microwave only
* PIR: PIR mode only
* HF+PIR: both PIR and microwave mode, to decrease the detection capability and detection area. Only when both detections are
activated, the motion is considered valid. This is to prevent the sensor from false trigger by heat source, air conditioner,
ventilation fans, water pipe and elevators etc...
* HF/PIR: either PIR or microwave mode, to increase the detection capability and detection area;
4 optional detection modes via remote control:

Distance Recommended between Sensors
Pay attention: The RF signal could be affected by big metal
plate & wireless devices such as GSM mobile antenna, strong
Wifi signal, ultra high-voltage cable which emits frequent
electromagnetic waves radiation, which may interfere with the
RF transmission and communication! Please always check the
application environment before mass installation!
We recommend the mounting distance between sensors to be
more than 6m to avoid sensors from being false-triggered.

Functions and Features
Tri-level Control (Corridor Function)
1
Hytronik builds this function inside the motion sensor to achieve tri-level control, for some areas which require a light change notice
before switch-off. The sensor offers 3 levels of light: 100%-->dimmed light (natural light is insufficient) -->off; and 2 periods of
selectable waiting time: motion hold-time and stand-by period; Selectable daylight threshold and freedom of detection area.
