FUNCTIONS
1. ON/OFF Function (stand-by period set to "0"s)
1. With sufficient ambient
light, the light will not
switch ON even if motion
signal is present.
2. With sufficient ambient
light, the sensor switches
on the light when motion is
detected.
3. After elapse of hold
time, the sensor switches
off the light when no
motion is detected.
1. If there is no motion
detected, the light will
remain at a low level
light all the time.
1. With sufficient
ambient light, the
light will not be
switched on even if
motion signal is
present.
3. After elapse of
hold time, the sensor
dims the light at low
light level if no new
motion is detected.
4. After elapse of
standby period, the
sensor switches off
the light if no motion
is detected in the
detection zone.
2. With sufficient
ambient light, the
sensor switches on
the light when
motion is detected.
2. When motion is detected,
the sensor will switch on the
light to 100% brightness.
3. After elapse of hold time,
the sensor dims the light at
the present low light level if
no motion is detected.
2) 2-step dimming function (stand-by period be set to “+∞”)
3) 3-step dimming function (stand-by period be set to “10s/1min/3min/5min/10min/30min”)
Note
1. “N/A”means not available.
2. Detection area is effected on volume of motion object and motion speed. The detection area is
tested by a 165cm height person and walking speed is 0.5m/s.
