Installing the detector

1. Lift off mounting plate (see Figure 2, item 1).
2. Fasten the mounting plate to the ceiling in the required
position using mounting holes (see Figure 2, item 2).
Specified mounting height: min. 2.5 m (8 ft. 2 in.), max.
5.0 m (16 ft. 5 in.). Specified screws: DIN 7996, 4 mm.
3. The detection pattern can be adjusted by up to ±15°
(max 30°) by rotation of the mounting plate prior to
tightening the screws.
4. Wire the detector (see Figures 2 and 6).
UL/cUL installations: All wiring must be made according
to National Electrical Code, NFPA70, and CSA C22.1,
Canadian Electrical Code Part I, Safety Standards for
electrical Installations.
Increase of mounting heights beyond the specified 2.5 to
5.0 m (8 ft. 2 in. to 16 ft. 5 in.) will reduce sensitivity.
Range varies from 12 to 14 meter (39 ft. 4 in. to 45 ft.
11 in.) in short range and 20 to 22 meter (65 ft. 7 in. to
72 ft. 2 in.) in long range depending on the mounting
height.
Note: The arrow (Figure 2, item 4) indicates the centre
curtain direction and the active direction when switch 4 is
OFF.
5. Select the desired jumper and DIP switch settings (see
Figure 3). See section "Setting the detector" below for
more information.
6. To screw the sensor module to the mounting plate, use the
screws that are placed for transport in the mounting plate
(see Figure 2, item 5).
The curtain directions 1 through 9 clockwise, are indicated on
the mounting plate (see Figure 2, item 6). Curtain number 5 is
the centre curtain.
Selecting the coverage patterns
For access to the mirror undo screws (Figure 2, item 7) and
open the sensor module (Figure 2, item 8). Mask the
appropriate mirror curtains with the adhesive labels provided
and reassemble the sensor module (see Figure 4 for example).

Setting the detector

See Figure 3 for the jumper locations in the detector.
J1: Setting LED
On: Enables the tri-color LED on the detector at all times
(factory default).
Off: Disables the tri-color LED on the detector at all times.
Removed: Puts the tri-color LED under the control of the Walk
Test and Day/Night input. This activates the memory feature of
the detector. When the detector is Disarmed and the input
Walk Test is disabled, the microwave section is turned off for
DD669-U. In this configuration the detector operates as a PIR
only. See "Alarm memory" below.
SW 1: Polarity setting of the control voltage (CV)
On: Active High. Provides the standard logic with "Active High"
logic to enable Walk Test (WT), Day/Night (D/N), and Remote
Test inputs (factory default).
Off: Active Low. Provides "Active Low" logic to enable Walk
Test (WT), Day/Night (D/N) and Remote Test inputs.
P/N 146446999-1 • REV A • ISS 25JAN12
SW 2: µW only / Dual mode
On: µW only mode. Consequently the PIR circuitry is switched
off and the detector will only signal alarms caused by the
microwave circuitry.
Off: Dual mode. In dual mode the detector signals an alarm
when both technologies (microwave and PIR) have identified a
target moving in the protected area (factory default).
SW 3: Detector range
The microwave can be selected between 20 ±0.5 m, and
12 ±0.5 m (65 ft. 7 in. ±1 ft. 8 in., and 39 ft. 4 in. ±1 ft. 8 in.)
Note: Only the microwave range will be reduced, not the PIR
section.
SW 4: Detection coverage
The detection coverage can be selected between 360 degrees
for normal application, and 180 degrees for special
applications.
Note: Only the coverage of the PIR will be adjusted.

Alarm memory

Depending on the inputs, the detector can store alarms in its
memory, or indicate them.

Walk testing the detector

The DD669-U provides a walk test mode for testing the
detectors operation and coverage pattern if the detector is set
to LED's disabled. To walk test the detector, remove the supply
voltage and apply it back on. The walk test mode can be
started once the startup sequence has completely finished
(LED flashes for 45 seconds). The unit stays in walk test mode
for 30 minutes. The detector returns to normal operating mode
after the walk test mode times out.
Green mode
The detector can be programmed in several ways to minimize
the exposure of microwave radiation to human and animal,
although the detector is already sending microwave signal on a
very low power level.
To activate the green mode:
• Remove jumper J1, so the DD669-U detector is under
control of the Day/Night and Walk Test inputs.
• Set DIP switch SW 1 to On (factory default) so the
Day/Night and Walk Test input are active high.
• Set DIP switch SW 2 to Off (factory default) so the
detector is in the dual mode.
Description
Alarms are indicated via relay
(no memory).
Walk Test mode, alarms are
indicated via LED and relay.
Alarms are indicated via relay
and stored in the alarm
memory.
When switching to the Day
mode, detector indicates alarms
stored in its memory by a
blinking LED.
