Section 1
General Description
The DH97 is a 4-row microprocessor controlled active
infrared presence detector for all types of automatic
doors.
• Wide and narrow pattern width of the
sensor is adjustable by twin revolving lens
units.
• 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, 15, 60 or 180 seconds).

Mounting and Wiring (continued)
5. Set desired sensor parameters as noted in Sections
5 & 7.
6. Place cover on sensor and clean the sensor.
NOTE: For maximum pattern depth and width,
mount the DH97 at 10 feet and use the
maximum pattern angle (10º).
NOTE: The DH97 can be mounted using the
optional DH97-BDB or DH97-MP mounting
brackets when more flexible mounting is
required (See Page 5).
Section 5
Dip Switch Settings
1&2 Presence Timer: Timer is adjustable using
switches 1 and 2. 1 to 4 Rows will detect a
stationary object for the time period set by the
Presence Timer. The timer will reset and begin if
any movement is detected.
3&4 Pattern Depth (Rows): To adjust the pattern
depth, set switches 3 & 4 as shown.
5&6 Frequency: 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).
7 Monitor Mode: A Snow Mode is available. Snow
Mode should only be used in environments with
heavy snowfall or other extreme conditions.
8 Self-Monitoring: "ON"=When power is first
supplied to the DH97, the sensor automatically
performs a Self Diagnosis (See Section 9).
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.
When carrying out the following work, TURN OFF THE
POWER:
1. When the floor conditions change.
2. Adjusting pattern or sensitivity.
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
10º (5 steps).

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
Section 9
Self Monitoring
Infrared beams are received on the receiver side of the
DH97, then the following occurs. For 12 seconds, the
relay starts chattering ON/OFF (4 times in 12 seconds).
Then the relay remains in the ON condition for 60
seconds. The cycle then repeats itself. At the same time,
the Indicator LED will switch continuously between RED
and GREEN. The door will remain in an Open position
throughout.
*****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
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
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)
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 to
reprogram
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)
