the detecting functions of the detector. To enable/disable
the PIR/light sensors, users can send system On/Off
command via UnetSystem. System On is for enabling
the detecting function; whereas System Off is for disabling
the detecting function. Please refer to the user manual of
UnetSystem for more operating instructions.
Note: The default value is enabled. Reconnection of
power supply will enable the sensor detecting function
automatically.
Sensitivity Level (PIR sensor only)
In order to provide a best efficiency of the detector, it is
recommended to test the detector with movements from a
farthest end of the coverage area at the first time of use.
If movements cannot be detected sensitively, simply adjust
the sensitivity level. The sensitivity level can be set from 1
to 10; the larger the number, the higher the sensitivity.
Note: The default value is set in 6, which implies medium
sensitivity.
Re-trigger Interval Setting (PIR sensor only)
This function is designed for setting the interval which
allows PIR sensor to be re-triggered after the detector has
been triggered. For example, the interval is set for 20
seconds. If a movement is detected, only wait after 20
seconds the detector can be triggered again if it detects
another movement. No response will be made if the
detector detects a movement in the meantime (FIGURE 7).
The time interval can be set from 5 seconds to 3600
seconds; the larger the number, the longer the interval.
FIGURE 7
Note: The default value is set in 5, which implies that the
detector can only be re-triggered after 5 seconds of
interval.
On-Off Duration Setting
The function of on-off duration setting will be useful if the
detector is connected with a module or lighting. Once the
associated appliances are activated (turn to “On” status)
after the detector has been triggered, they can be set to
turn off after 5 to 3600 seconds of duration which is set by
users beforehand. The larger the number it is, the longer
the duration it will be.
FIGURE 8
Note: The default value is set in 15, which implies that the
detector will send a trigger-off command to associated
appliances 15 seconds after been triggered.
Percentage of Lux Level Setting
The user can set a detecting percentage of lux level for
triggering light sensor when a movement is detected. If
the percentage of lux level of ambient illumination falls
below this percentage, and a person moves across or
within the protected area, the detector will emit RF signal
to control panel or connected modules and lightings.
Percentage can be set from 1% to 100%; the larger the
percentage, the higher the detecting lux level (the higher
the brightness).
Note: The default value is set in 10, which implies 10% of
lux level. You can check the percentage of current
ambient illumination via UnetSystem before setting the
percentage of lux level.
