Description/Operation

The Dual Technology sensor’s combination of Ultrasonic and Passive
Infrared technologies offers the most complete sensing equipment
available today. This pairing helps eliminate false deactivations for
additional energy savings. 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.
The lights are turned ON by activating a momentary switch (model
# GMDS-*) that is connected to the sensor. When enabled, the
Daylighting feature prevents lights from turning ON when the room
is adequately illuminated by natural light.
