DT·900 Series DUAL TEC
Light Industrial Applications - Installation Instructions
Step 1
Select mounting height.
30 cm (12") minimum
4 m (12')
2 m (6')
Mounting Location Guidelines
Avoid direct or reflected sunlight, infrared light.
Aim sensor away from windows, heating/cooling devices or
large moving objects.
Sensor must have a clear line-of-sight to protected area.
Keep at least 1 meter (3') of space in front of sensor clear.
Step 5
Locate correct sensor range scale and
rotate Vertical Adjustment Screw until the
diamond corresponds to the sensor
mounting height (coarse adjust).
NOTE: Fine adjust may be needed during
walk-test. See Supplemental Information.
Step 9
Unfasten screws and remove mounting
plate from sensor.
Step 13
Hang the sensor on the mounting plate
hooks and fasten with the two mounting
plate screws.
Step 17
Apply power to sensor and prepare for
walk-test.
Wait 90 seconds for power-up self-test
to run. All LEDs will flash.

NOTE: LEDs flashing after 90 sec. = defective
Step 21
Rotate horizontal fine adjust knob to the
desired position.
NOTE: Fine adjustment allows for small
changes (3 degrees right or left) between
coarse settings.
Step 2
Carefully push screwdriver into slots to
disengage latches and open top cover.

Step 10
Attach mounting plate to wall at desired
height, using four fasteners (not
supplied).
Step 14
Wire the unit
as shown.
2
Use 2.0 - 0.3 mm
(14 – 22 AWG)
NOTE: Secure
wires to
mounting plate with
tie wraps.
Step 18
Turn the microwave potentiometer
counterclockwise to decrease the
microwave range to minimum.
During walk-test, gradually turn the
potentiometer clockwise increasing
microwave sensitivity until the desired
range is obtained.
Step 22
Tighten horizontal fine locking screw on
PCB.

Firmly insert screwdriver into slot in arrow
and rotate PIR Mirror Selector to the
correct range.
Step 7
Select INFORMER® mode with switch
S2 if desired. (See Supplemental
Information).

Step 11
Install M5 (#10) screw in wall 1.9 cm
(3/4") below mounting screw, as shown,
for tamper activation.
Step 15
Loosen horizontal locking screw in
sensor support base.
Step 19
Walk-test the sensor to check for
adequate detection coverage and to
verify the sensor is fully functional. Two to
four normal steps should make the LEDs
light and trigger an alarm.
NOTE: If an on-going self-test problem, mask
condition or an INFORMER condition occurs, the
LEDs display a pattern that identifies the trouble.
See Supplemental Information (Table 3).
NOTE: When there is no motion in the
detection area, all three LEDs should be off.
Step 23
Tighten horizontal locking screw in
sensor support base.
Step 4
Set switch S4 to establish microwave
range.

Step 8
Carefully push screwdriver into slot to
disengage latch and remove bottom
cover.
Step 12
Pull about 30 cm (12") of wire from wall
through the opening in the mounting
plate and route wire to the terminal strip.
1.9 cm (3/4")
Step 16
Grasp housing and rotate it to the desired
position (coarse adjust). If fine adjust is
needed see Steps 20 - 22.
NOTE: Reference marks = 5° change.
Step 20
For finer horizontal adjustments, loosen
the PIR horizontal fine locking screw on
PCB.
Step 24
Remove jumper at J5, on the PCB, to
disable the LEDs after walk-testing.
Step 25
Complete installation by closing top
cover and replacing bottom cover.
