Section 1
General Description
The DH400 is a high mount microprocessor controlled
active infrared presence detector for all types of
automatic doors.
•Wide and narrow pattern width of the sensor
is adjustable.
•Pattern depth and width are
adjustable using mounting height,
dip switches, pattern width and
pattern angle adjustments.
•Frequency is selectable in four channels
•Self-Diagnostic means the sensor continuously
monitors itself.
•Snow Mode Switch ensures against false operation
caused by snow, insects, etc.
•Microprocessor provides programmable Presence
Timer (2 sec., 30 sec., 60 sec., or infinity).

 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.

•After the “Doorway Learn” process is completed,
sensor is in standby mode.
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.

2. Pattern Width Adjustment.
Pattern Adjustments for single and/or double doors.
See Section 5: Dip Switch Settings for details on dip
switch settings adjustments for Detection Depth and
Width.
Further depth adjustments can be made using the Depth
Adjustment Screw. Rotate clockwise to obtain outermost
setting of 15°. Rotate counter-clockwise to adjust
minimum/innermost setting to 0°.
Section 8
Verification of Operation
1. After mounting, setting parameters and applying
power, walk test unit to verify detection pattern.
2. If the door does not operate properly, recheck the dip
switch settings and pattern adjustments.
3. After rechecking, if there is still a problem, adjust the
sensitivity.
•Adjust high (clockwise) to increase sensitivity.
•Adjust low (counter-clockwise) to decrease
sensitivity.
APPLY ONLY SMALL TORQUE

Self Monitoring
When the sensor has an internal sensor error, the door
will remain open and the Green/Red LED blinks
alternately.

Self Monitoring (cont.)
*****EXTREMELY IMPORTANT*****
After final set-up, test unit(s) completely to ensure that
proper coverage has been achieved (width, depth and
location of the pattern must be tested).
After the installation and operational check of the
system:
1. Place the proper labels on the door per ANSI/BHMA
A156.10 & BS 7036.
2. Instruct the owner of the door system operation and
how to test it. This should be checked on a daily
basis.
3. Instruct the owner on what to do if the door or any of
its components become damaged.
4. Strongly recommend to the owner that the complete
entry be inspected twice a year as part of the service
agreement.
Section 10
Troubleshooting
PROBLEM 1: Door does not open
LED STATUS: Off
CAUSE 1: Sensor Connector
SOLUTION 1: Tighten connector or reconnect
CAUSE 2: Power Supply
SOLUTION 2: Check that the power supply is properly
connected and 12V to 24V AC or DC
CAUSE 3: Sensor Wiring
SOLUTION 3: Double check sensor wiring.
PROBLEM 2: Door operates by itself (ghosting)
LED STATUS: Door Opens=RED, Door Closes=Green
CAUSE 1: There is an object moving in the
detection area
SOLUTION 1: Remove the moving object from
detection area
CAUSE 2: Sensitivity too high
SOLUTION 2: Turn down sensitivity
CAUSE 3: Dust, frost or water droplet on the
sensor lens
SOLUTION 3: Wipe sensor lens with clean cloth and
install a weather cover if necessary
CAUSE 4: Detection pattern is too far from the
door, detecting people passing by
SOLUTION 4: Adjust detection pattern
CAUSE 5: Detection area overlaps with that of
another sensor
SOLUTION 5: Ensure different frequency setting for
each sensor
CAUSE 6: Detection of falling snow, insects,
leaves, etc.
SOLUTION 6: Adjust the Monitor Mode
PROBLEM 3: When door opens or closes, LED ORANGE
LED STATUS: ORANGE
CAUSE 1: Detection row “ROW 1” (”ROW 2” when
“Doorway Learn” is turned ON) is
focused too close to the door
SOLUTION 1: Adjust detection depth of rows away
from the door
PROBLEM 4: Door opens and remains in the open
position
LED STATUS: RED
CAUSE 1: Detection area changed, while infinity
presence timer setting is in use
SOLUTION 1: Repower the sensor or change the
presence timer settings to 30 or 60
seconds
CAUSE 2: Incorrect Sensor Wiring
SOLUTION 2: Double check sensor wiring
CAUSE 3: Reflected Signal Saturation
SOLUTION 3: Remove highly reflective objects
from the detection area, or lower the
sensor sensitivity
LED STATUS: GREEN/RED FLASH
CAUSE 1: Internal Sensor Error
SOLUTION 1: Replace the sensor
