1 Tri-level Control (Corridor Function)

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.

Zero-cross Relay Operation

Designed in the software, sensor switches on/off the load right at the zero-cross point, to ensure that the in-rush current is minimised, enabling the maximum
lifetime of the relay

24h Daylight Monitoring Function

Our innovative and patented software enables our antenna with built-in daylight sensor to provide a “smart photocell” function. This
function is activated when stand-by period is set to “+∞ ”.

  • Settings on this demonstration:
  • Hold-time: 10min
  • Daylight threshold: 50lux
  • Stand-by dimming level: 10%
  • Stand-by period: +∞
Daylight Monitoring Function

Manual Override

This sensor reserves the access of manual override function for end-user to switch on/off, or adjust the brightness by push-switch,
which makes the product more user-friendly and offers more options to t some extra-ordinary demands:

Short Push (<1s): on/off function;
On → Off: the light turns off immediately and cannot be triggered ON by motion until the expiration of pre-set hold-time. After this period, the sensor goes back to normal sensor mode.
Off → On: the light turns on and goes to sensor mode, no matter if ambient Lux level exceeds the daylight threshold or not.
* Long Push (>1s): adjust the hold-time brightness level between10% and 100%.
Note: if end-user do not want this manual override function, just leave the “push” terminal unconnected to any wire.

Semi-auto Mode

It is easy to forget to switch off the light, in ofce, corridor, even at home. And in many other cases, people do not want to have a sensor to switch on the light automatically, for example, when people just quickly pass-by, there is no need to have the light on. The solution is to apply this “absence detector”: motion sensor is employed, but only activated on the maunal press of the push switch, the light keeps being ON in the presence, and dims down in the absence, and eventually switches off in the long absence.
This is a good combination of sensor automation and maunal override control, to have the maximum energy saving, and at the same time, to keep efcient and comfortable lighting.

DIP Switch Settings for the motion sensor

Detection Range

Sensor sensitivity can be adjusted by selecting the combination on the DIP switches to it precisely for each specific application


Select the dip switch configuration for the full brightness on-time after presense detection.

Daylight Threshold

Set the level according to the fixture and environment. The light will not turn on if ambient lux level exceeds the daylight threshold preset. Please note that the ambient lux level refers to internal light reaching the sensor. Disabling the daylight sensor will put the sensor into occupancy detection only mode.

Stand-by period (corridor function)

This is the time period you would like to keep at the low light output level before it is completely switched off in the long absence of people.

Note: “0s” means on/off control;
“+ ∞ ”means the stand-by time is in infinite and the fixture never switches off.

Stand-by dimming level

The setting is used to select the desired dimmed light level used in periods of absence for enhanced comfort and safety
