Honeywell DT7550UK2 Installation Instructions Manual

❶ Select the mounting location.

❹ Wire the unit.

❸ Mount the unit.

❺a Walk-test the sensor.

Mounting Location Guidelines

• 2.3 m mounting height.

• Avoid direct or reflected sunlight.

• Aim sensor away from windows, heating/cooling devices
or large moving objects.

• Sensor must have a clear line-of-sight to protected area.

• Use a small screwdriver to unfasten the housing latch. Gently pull
apart the housings.

• Push outward on the PCB latch and lift the PCB out of the housing.

• Slide the wire through the wire channel in the back housing.

• Mount the back housing flat against a wall or in a corner.
Note: If using the Rear Tamper feature, refer to the Rear Tamper
section before mounting the sensor.

• Replace the PCB.

• Apply power to the unit. Initialisation is complete when the
LED stops flashing slowly.

• Adjust the microwave range to minimum setting (25%) by
turning the range adjustment counterclockwise using a
small screwdriver.

• Replace the front housing.

• Begin walking through the detection area.

- The LED will turn red, indicating an alarm detection.

• Increase the microwave range as necessary.

• Repeat the items in step 5a until proper detection range is
obtained.

• The sensor MUST be walk tested after every power up

to complete the power up mask detection test.

❺b Optional: Walk-test using Zone Finder.

• Use a screwdriver to short the test pads.

• During the Zone Finder walk-test mode, the LED turns:

- green for one second for every PIR detection;

- yellow for two seconds for every microwave detec­tion.

• Adjust the microwave range as necessary.

• Zone finder mode times out after ten minutes.

With Anti-Mask Motion Sensor Installation Instructions

Use the Zone Finder mode to identify the PIR and/or
microwave pattern. In Zone Finder mode the red
LED is disabled.

❷ Separate the sensor housings and remove the

printed circuit board (PCB).

Note: The cover screw,
when used, is installed
here.

For improved anti-mask
performance the look-down
mirror is disabled. To enable
look-down remove the mask.

Jumper

Position EOL Value

• Connect wires as shown using 0.2 - 1.3 mm2 wire size.
Observe proper polarity.

• If not using the integrated EOL resistors, remove jumpers from
all pins.

• If using the integrated EOL resistors:

1. Connect the sensor to the panel (see wiring diagrams on

the right; if using the two loop option, also cut link W1).

2. Place the jumpers on the appropriate fault, tamper and

alarm pin options (see table below).

Notes:

• Consult the Control Panel manual to determine proper EOL
selection.

• Fit only one jumper each for the fault, tamper and alarm
EOL settings.

With Anti-Mask Motion Sensor Product Information

REAR TAMPER

To use this feature:

1. Mark the retaining screw hole location:
For wall/surface mounting, remove the wall mount knockout
and mark the mounting hole location.
For corner mounting, use a sharp, pointed tool to pierce the
thin plastic in the corner mounting hole, and mark the
mounting hole location.

2. Mount the rear housing in the desired location, and use a #6
pan-head screw in the selected Rear Tamper retaining screw
hole.
Important: For best results, mount the sensor housing to a
stud, solid wood, or a robust wall anchor.
Note: If an angled mounting is required, installing the sensor on a
wall using the corner mount holes will only be TS 50131-2-4 compliant if installed
using the Rear Tamper. Alternatively, the SMB-10T mounting bracket can be
used to achieve TS 50131-2-4 compliant angled mounting.

RELAY OPERATION

1

For information on Fault conditions, see the Troubleshooting section.

2

In a Mask condition, the Alarm and Fault relays will activate simultaneously,
and remain open until the condition has been cleared.

3

In a Fault condition, the Fault relay will latch open until the Fault condition has
been cleared.

To ensure communication clarity, the operation of the Alarm and Fault relays
have been prioritized as follows:

Note: In situations where multiple
conditions occur at the same time,
the highest priority condition signal
will take precedence after all
conditions present have been
signaled.

MASK FUNCTION

Power Up Anti-Mask

At power up, the sensor initiates the power up mask detection test. The power up mask test will be completed ONLY
after both the PIR and Microwave technologies are verified by a walk test and an alarm is signaled.

IMPORTANT: The sensor MUST be walk tested after every power up to complete the mask detection
test. If not walk tested, the sensor will remain in power up anti-mask test mode indefinitely, and will
issue a mask signal if a set number of microwave events occur before a PIR event.

Normal Anti-Mask Operation

The sensor signals a mask condition when a variety of materials and reflective objects are placed in front of the
sensor. To avoid false mask alarms, follow the mounting guidelines shown in Step 1.

Clearing an Anti-Mask Condition

Visually inspect the sensor and remove any materials blocking the sensors view. The sensor will clear an anti-mask
condition when detection on both the microwave and PIR resume based on the setting of switch 3. With switch 3 in
the off position, three valid alarm detections will clear the mask condition. With switch 3 in the on position, one valid
alarm detection will clear the mask condition.

*FAULT CONDITIONS:

1

Low Voltage: The sensor is disabled.

2

Three possible conditions:

• Microwave Supervision failure: The sensor is operating in PIR mode only.

• PIR self-test failure: The sensor is disabled.

• Temperature Compensation failure: The temperature compensation is disabled.

Depending on the Fault condition, take the following corrective actions:

• Verify the power supply is sufficient .

• Cycle power to the sensor.

• Walk test the sensor.

• Verify the sensor is not blocked or masked.

If the Fault condition does not clear, replace the sensor.
