ST41
Instruction
Welcome to use ST41 infrared motion sensor!
The product adopts good sensitivity detector, integrated circuit.
It gathers automatism, convenient safe, saving-energy and practical
functions. It utilizes the infrared energy from human as control-signal
source, it can start the load at once when one enters detection field.
It can identify day and night automatically. It is easy to install and
used widely.
SPECIFICATION:
Power Sourcing: 220V/AC-240V/AC
Power Frequency: 50Hz
Ambient Light: 3-2000LUX (Adjustable)
Time-Delay: min.10sec±3sec
Max.7min±2min
Rated Load: 1200W (incandescent lamp)
300W (energy-saving lamp)
℃)
Detection Distance: 6m max (<24
FUNCTION:

Identify day and night automatically. Can adjust ambient light according to your desire: when
turn to SUN (max), it will work in the daytime and at night. When turn to MOON (min), it will
only work under less than 3LUX circumstance. As for Adjustment, please refer to testing
way.

Time-delay is added continually: when it receives the second induction signal after the first
inductor, it will compute time once more on the rest of the first time-delay basic (Set time) .

Time-delay adjustment: it can be set according to your desire. The minimum is 10±3 sec;
the maximum is 7±2min.
INSTALLATION: (as following drawing.):

Turn off the power.

Moving the transparent vinyl cover what is in the bottom of the sensor.

Loosing the screws in the connection terminal, connecting the power and rated load to
connection terminal of sensor according to connection sketch map.

Tighten the screws; put the transparent vinyl cover into the original station.

Folding the metal spring of the sensor to upwards, until they are in "I" position with sensor,
then put the sensor into the hole or installation box what is in the ceiling, the size is similar
with item. Releasing the spring, the sensor will be set in this installation position.
