Wire Preparation
Pluggable screw terminal. It is recommended to make
connections to the terminal before fitting to the sensor.
3. Functions
It is easy to forget to switch off the light, in office, 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 manual press of the push-switch,
the light keeps being ON in the presence, and switches off in the long absence.
Note: end-user can choose either function 3.3 or function 3.4 for application.
Default function is manual override.
Semi-auto Mode (Absence Detection)3.4
Manual Override
With the help of push-switch, this sensor can be over-ridden by the end-user to manually switch
on/off the light, which makes the product more user-friendly and offers more options to fit some
extra-ordinary demands:
3.3
* 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.
Note: if end-user do not want this manual override function, just leave the “push” terminal
unconnected to any wire.
zero-cross point
Alternating current
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.

2. Installation
On/off Control3.1
This sensor is a motion switch, which turns on the light upon detection of motion or breathing,
and turns off after a pre-selected hold-time when there is no movement or breathing. A daylight
sensor is also built in to prevent the light from switching on when there is sufficient natural light.
Note:
1. We recommend the mounting distance between sensor to sensor should be more than 2m to
prevent sensors from false-triggering.
2. The face-to-face installation between sensors and sensors or other radio sources is not
recommended, or false trigger issue will potentially behave.Make sure the installed environment is
free of any obvious vibration, strong air blows, curtain swing, water flow in pipe ……The
recommended mounting distance between sensor to sensor is >3m to prevent sensors from
false-triggering and furtherly adjust per actual environment.
Lux Off Function3.2
The built-in photodiode will also automatically turn off the light when the ambient natural light
exceeds the programmed lux level for more than 5min, regardless of whether motion is detected
or not.
