5.2.2 The detection coverage of sensor can be changed by using the metal shield
which is helpful to avoid the undesired detecting area in order to reduce the
false triggering problem. Please refer to the below illustrations for the effect
of using one or two metal shields.

Below are some examples of installation in different kinds of lighting fixtures for
reference. Ensure the sensor module is installed at least 60mm far away from
ballast, lamp holder, or bulb with filament (See FIG.1).

INSTALLATION AND WIRING
This sensor module is suitable for integrating into a variety of lighting fixture made
of different kinds of materials (e.g. glass, acrylic, PVC) and lamps (For example,
the fluorescent light, incandescent lamp, PL lamp, etc.) subject to having sufficient
space inside the lighting fixture for installation. Select a proper lamp and refer to
section 2 for installation.

NOTE
Indoor application mainly, higher sensitivity in a smaller interior space.
When the sensor is mounted under eaves use, it is recommended to be
above 5m away from the borders of corridor to avoid false trigger by raining
or snowing (See FIG.6).

NOTE
7.2 Manual override for switching light on for 4 hours ( Lux
is independent )
When sensor is standby under the auto mode, the sensor can be bypassed to turn
the light(s) on for 4 hours by series connecting a power supply switch with the L
terminal of mains power and the S terminal of sensor (refer to the FIG. 11 for
wiring), the LED will be on 1sec & off 5sec repeatedly during this period.
When the light is on,
switch the power supply switch “off
→
on
→
off
→
on
within 2sec“, afterwards, light will turn off for 2sec. then on to confirm that
sensor has entered into manual on 4 hours mode.
In the manual on 4 hours mode, the sensor can be set to auto mode by
switching the power supply switch “off
→
on within 1sec“, afterwards, light will
be off for 2sec. then enter into auto mode and sensor follows the VR settings to
work.
When the light is off,
switch the power supply switch “off
→
on
→
off
→
on
within 2sec“, afterwards, light will change its status from on 3sec & off 2sec &
on to confirm that sensor has entered into manual on 4 hours mode.
The operations are as under mentioned :
If the power supply is discontinued 2sec., the sensor will reboot and run
30sec. warm-up time again.
