Direction Detection:
When set to ON, pedestrians
moving away from the sensor will NOT be detected.
NOTE:
For pedestrian safety purposes when
“Doorway Learn” is set to ON, the 1st and 2nd row
of detection will detect pedestrians regardless of
direction of movement.
Doorway Learn:
Allows the 1st row of detection to
be focused inside the door close area without
detecting the door movement.
NOTE:
When “Doorway Learn” is turned ON, the
sensitivity level of the 1st row of detection is at
maximum only when the outer rows of detection
are activated.
Section 6
Power & “Doorway Learn” Setting
BEFORE APPLYING POWER, READ AND FOLLOW THESE
INSTRUCTIONS:
When power is applied, the sensor will read and store the
environmental optical parameters. This is necessary for
Presence Detection to work properly.
1. CLEAR THE AREA OF ANY UNNECESSARY OBJECTS.
2. Apply POWER.
3. Vacate the Detection Pattern immediately. While the
sensor sees ANY moving objects in its DETECTION
PATTERN, it will not proceed to the following step.
4. DO NOT enter DETECTION PATTERN for 10 seconds
(Presence Detection Setting).
5. TEST the presence feature, especially near the door.
When carrying out the following work, TURN OFF THE
POWER:
1. When the floor conditions change.
2. Adjusting pattern or sensitivity.
“DOORWAY LEARN” is OFF
(Ref. Sec. 5-Dip Switch Settings)
• Upon power ON, the solid Green LED turns on
indicating that the sensor is in standby mode and
ready to detect.
“Doorway Learn” is OFF
(Cont.)
Presence Detection: It takes 10 seconds after the sensor
powers up for presence detection to be initiated on all
rows of detection. If someone enters the detection area
before 10 seconds has elapsed, the sensor will continue
to initialize until after 5 seconds with no motion being
detected.
“DOORWAY LEARN” is ON
(Ref. Sec. 5-Dip Switch Settings)
• Upon power ON, the Red LED indicates a door open
relay output to begin the “Doorway Learn” process.
• Green LED blinks for 37 seconds while the “Doorway
Learn” process is carried out. Door opens/closes.
