Description/Operation
The MicroSet self-adjusting technology continuously monitors
multiple sub-frequencies in the event that if a continuous Doppler
shift occurs, such as those created by airflow from an air duct, the
sensor will identify the noise as continuous and then block it out of
view at a select sub-frequency. It will continue to monitor other sub-
frequencies for human motion. This avoids false-activation, while still
maintaining the high level of sensitivity that is necessary for sensing
minor motion in a changing environment. Separate concurrent time
delays for both Passive Infrared and Ultrasonic technologies avoid
false activations or deactivations. In Automatic On Mode, the lights
turn ON when a person enters the room. In Manual On Mode (-R
model only), the lights are turned ON by activating a momentary
switch (model # GMDS-*) that is connected to the sensor. When
enabled, the daylighting feature (-R models only) prevents lights from
turning ON when the room is adequately illuminated by natural light.
