This detector has Dual
Edge Sensing (DES)
Technology,
developed to eliminate
false alarms yet still
provide maximum
security.
The detector uses a
pattern of infrared
beam zones to sense
body movement. The
detection pattern in an
optimal temperature
environment is shown
in figure 9.
Each time you walk
into or out of an
infrared beam zone
this will be sensed and
processed by the DES
technology built into
the detector. The red
trigger light will not
turn on until the
detector has made a
valid movement
detection in normal
mode.
