Section 1
General Description
The DH94D is a floor reflection method (FRM) active
infrared presence sensor designed to provide medium
range safety detection for automatic sliding doors. The
DH94D is the ideal solution for entrances with a shallow
approach or for adding threshold protection to any sliding
door.
• Pattern depth adjustable from curtain-like
1 row up to 4 rows via dip switches.
• Pattern angle adjustable 0-5 degrees
via mechanical rotation of the sensor
housing.
• Pattern width adjustable via mechanical knobs.
• 4 frequency settings to avoid interference from other
sensors in close proximity.
• Self-monitoring microprocessor controlled diagnostics
includes automatic countermeasures againse adverse
conditions such as falling snow, rain, flying insects,
strong sunlight and electrical noises.
• 4 presence timer settings: 2, 15, 60 and 180 seconds.

4. Ensure snow or water can not accumulate on floor.
5. Ensure a minimum of reflected sunlight from the
floor.
6. Avoid steamy environments.
7. Use different frequency settings for sensors in close
proximity.
8. Use Infrared Safety Beams when required.
Section 4

4. Connect wiring. Push amp connectors tightly
together.
5. Place connector in holder.
6. Set desired sensor parameters as noted in Sections
5 & 7.
7. Place cover on sensor and clean the sensor.
NOTE: For maximum pattern depth and width,
mount the DH94D as high as possible and use
the maximum pattern angle (5º).
Section 5
Dip Switch Settings
1 Presence Timer: Delay is adjustable using dip
switches 1 & 2. The DH94D will detect a stationary
object only for the time period set by the Presence
Timer. The timer will reset and begin if any
movement is detected.
2Pattern Depth (Rows): To adjust the pattern depth,
set switch 3 & 4 as shown.
3Frequency: When more than two sensors are used
in close proximity to each other, to prevent
interference use alternate frequency settings. (H +
MH + ML + L = Maximum 4 sensors).
4 Monitor Mode: A snow mode is available using
switch 1. Snow Mode should only be used in
environments with heavy snowfall or other extreme
conditions.
5 “ON”: When power is first supplied to the sensor, the
DH94D performs self-diagnostics.
Section 6
Power
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.

Section 7
Adjusting Detection Pattern
Adjust the detection pattern according to the following
diagrams:
1. Pattern Angle Adjustment.
• The body of the sensor can be rotated from
0º to 5º (3 steps).
2. Pattern Width Adjustment.
Mask Adjustments for single and/or double doors.
Detection pattern will vary according to
objects, material, color and speed.
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.
*****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 or any other applicable standard.
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 9
Troubleshooting
PROBLEM 1: Door does not open.
CAUSE 1: Sensor Connector
SOLUTION 1: Tighten connector or reconnect
CAUSE 2: Power Supply
SOLUTION 2: Check that the power supply is properly
connected
PROBLEM 2: Door operates intermittently.
CAUSE 1: Sensor is very dusty or covered in water
drops, etc.
SOLUTION 1: Clean the sensor (do not use thinner or
alcohol to clean sensor)

PROBLEM 2: Door operates intermittently.
CAUSE 2: Sensitivity too low
SOLUTION 2: Turn up sensitivity
CAUSE 3: Detection pattern in the wrong position
SOLUTION 3: Alter the detection pattern by changing
sensor angle, dip switch settings and/or
pattern width adjustments
PROBLEM 3: Door operates by itself
CAUSE 1: Sensitivity too high
SOLUTION 1: Turn down sensitivity
CAUSE 2: Another sensor is too close by
SOLUTION 2: Change the frequency to each sensor
CAUSE 3: Sensor detects the door movement
SOLUTION 3: If the indicator LED is an Orange color,
adjust the pattern depth angle away
from the door
CAUSE 4: There is a cloth mat in the detection
pattern
SOLUTION 4: Turn the sensor power off and then on
again, and allow it 10 seconds
CAUSE 5: Detection pattern too far in front of the
door, detecting people passing by
SOLUTION 5: Adjust the detection pattern - move it
closer to the door
CAUSE 6: The condition of the monitored area is
varying (i.e., dusty, dirty, snow)
SOLUTION 6: The condition of the detection zone can
change due to heavy dust or dirty, heavy
snow or footprints being left in fresh
snow. This will cause the door to open
sometimes. Set the Presence Timer to a
short time. (See Section 5)
