The LOS2400 sensor “sees” 
infrared heat changes caused by 
the motion of people within its
detection zone and turns on lights
automatically.

How long do the lights
stay on?

Lights stay on as long as motion 
is detected. They turn off a short time
after motion in the detection range stops.
You can adjust this time from 6 to 15
minutes. Since the lights are only on
when needed, and the sensor uses a
negligible amount of power, the 
savings in energy costs are substantial.

How much motion is necessary
to keep lights on?

A 6" wave of a hand or head tilt once
every 6 to 15 minutes is sufficient to
keep the lights on.

How do you adjust the
sensor?

Time delay and sensitivity adjustments
are located on the back of the unit. An
LED indicator on the front panel shows
when motion is detected and aids
installation testing.

How large an area does the
LOS2400 cover?

At a 9 foot mounting height, the 
maximum coverage is 2000 square feet.
At a 20 foot mounting height, the 
maximum coverage is 2500 square feet.
The detection pattern covers 360
degrees from the sensor location in the
following pattern:
