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.
