DH100-CT

Sliding Pedestrian Door Motion & Presence Sensor INSTALLATION INSTRUCTIONS

NOTE: Set up for this sensor should be

performed by an AAADM-certified installer.

Section 1

General Description

The DH100-CT is an active infrared presence sensor that
is designed to provide both activation and safety
detection for automatic sliding and folding doors in a
single device.

• Test Input provides sensor monitoring

capabilities as required by the latest
industry standard.

• Pattern depth and width are

adjustable using mounting height,

dip switches, detection area depth,
and detection area width adjustments.

• Frequency can be changed to prevent interference

from other sensors in close proximity.

• Self-Diagnostic means the sensor continuously

monitors itself.

• Monitor Mode Switch ensures against false operation
caused by snow, leaves, insects, etc.

• Programmable Presence Timer (2 sec., 30 sec.,

60 sec., or infinity).

Section 3

Mounting Information

1. Do not mount higher than 9.84 ft. (3m).

2. Mount within 50mm (1.97”) from bottom of header

cover.

3. Do not leave any objects which may move in the

detection pattern.

4. Avoid steamy environments.

5. Ensure rain or snow will not fall directly on unit.

6. Ensure snow or water can not accumulate on floor.

7. Ensure a minimum of reflected sunlight from the

floor.

8. Use different frequency settings for sensors in close
proximity.

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.

Door Hold: Switch to OPEN to hold the door in the open

position.

Doorway Learn: 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 inner row of detection is

!

only at maximum when the outer rows of

detection are activated.

Sliding Pedestrian Door Motion & Presence Sensor INSTALLATION INSTRUCTIONS

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.

Red solid LED

• Green LED blinks for about 10 seconds as “Doorway
Learn” process is carried out. Door opens/closes.

Green blinking LED

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

Green solid LED

Presence Detection: During the “Doorway Learn”
process, the outer 4 rows of detection on the DH100-CT
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.

Green blinking LED

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: When carrying out the following work,

turn off sensor power.

!

■ When the floor condition is changed by placing
a mat on the floor, etc.

■ When the detection area pattern or sensor
sensitivity is adjusted.

Section 9

Verification of Operation

1. After mounting, setting parameters and applying

power, walk test unit to verify detection pattern.

2. If the sensor does not function as expected, TURN
OFF THE POWER and RECHECK the Depth Adjustment
Lever Arms, Dip Switch and Width Mask Knobs as
described in Sections 5 and 7.

3. After rechecking, if there is still a problem, adjust the

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 all applicable

standards.

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 11

Troubleshooting

PROBLEM 1: Door does not open when person enters

the detection area.

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 is accurate.

PROBLEM 2: Door operates by itself (Ghosting).
LED STATUS: Door Opens RED,
Door Closes GREEN

CAUSE 1: Moving objects in detection area.
SOLUTION 1: Remove the moving object from the

detection area.

CAUSE 2: Sensitivity too high.
SOLUTION 2: Reduce sensor sensitivity.

CAUSE 3: Dust, frost or water droplet on the

sensor lens.

SOLUTION 3: Wipe the sensor lens clean and install a
weather cover if necessary.

Section 10

Self Diagnostics

A flashing Green/Red LED inducates any technical issues
with the HR100-CT. The frequency of the flashing
indicates the type of issue as explained below:

LEDs Flashing Fast = Please replace the sensor.

Green

Red

LEDs Flashing Slow = Confirm that sensitivity

potentiometer is set to maximum and re-power the
sensor. If the error persists, set Dip Switch 8 to “Low
Reflection”.

X

Green

Red

7898 Zionsville Road  Indianapolis, Indiana 46268

Telephone: [phone]  www.mssedco.com  [e-mail]

CAUSE 4: Detection area overlaps with that of

another sensor.

SOLUTION 4: Ensure different frequency setting for

each sensor.

CAUSE 5: Detection of falling snow, leaves,

insects, etc.

SOLUTION 5: Turn monitor mode Dip Switch
“Snow”.

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 Inner 3 rows
away from the door.

(/MANU) DH100-CTv1017

Y

3 to

Page 6

PROBLEM 4: Door opens and remains in open position.
LED STATUS: RED

CAUSE 1: Detection area changed, while ∞ infinity

presence timer setting is in use.

SOLUTION 1: Re-power the sensor or change the
presence timer settings to 30 or 60 secs.

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 FAST FLASH

CAUSE 4: Internal sensor error.
SOLUTION 4: Replace the sensor.

LED STATUS: GREEN/RED SLOW FLASH

CAUSE 5: Reflection of the transmitted infrared
signal from the floor is too low.
SOLUTION 5: Increase sensor sensitivity or change the
“Reflection Diagnostics” Dip switch 8
from “Normal” to “Low Reflection”.

LED STATUS: ORANGE BLINKING (Slow)

CAUSE 6: Door Hold (Dip switch 4 set to Open).
SOLUTION 6: Turn “Door Hold” Dip switch 4 to Auto.
