Presence Detection:
During the “Doorway Learn”
process, the outer 4 rows of detection on the DH400
sensor switch from motion detection to presence
detection 10 seconds after power ON. The inner
“Doorway Learn” row of detection will switch from motion
to presence detection after the “Doorway Learn” process
is complete.
“Doorway Learn” Failure & Recovery:
If a person enters
the detection area during the “Doorway Learn” process, it
may not be successfully completed. In this case, the
sensor will carry out the “Doorway Learn” process on
door activation caused by a person in order to build an
accurate image of the door open and door close position.
NOTE:
When “Doorway Learn” is turned ON, the
sensitivity level of the inner row of detection is at
maximum ONLY when the outer rows of detection are
activated.
CAUTION:
If you change dip switch setting or
sensitivity volume, the sensor will be reest.
During resetting, indiator LED is blinking with
orange color. Keep away from detection area.
After resetting, the sensor becomes the same
state as it is turned Power-on.
In case the product is used as a supplementary
sensor: Set the detection area of the 1st row
away from the door.
