EN: Installation instructions
Introduction
The DD66X/AM family is made up of Dual/Dual-AM motion
sensors. They have the patented Range Controlled Radar
technology.
Installation guidelines
The detector can be mounted to a ceiling. Use the following
guidelines to determine the best location to install the detector:
•
Mount the detector so the expected movement of an intruder
is across the detection pattern (Figures 4 and 5).
•
Mount the detector at a stable surface at a height between
2.5 m (8 ft. 2 in.) and 5.0 m (16 ft. 5 in.).
•
Do not mount the detector within 0.5 m (1 ft. 8 in.) of metallic
objects or within 1.5 m (4 ft. 11 in.) of fluorescent lights.
•
Do not place objects in front of the detector that may prevent
a clear line of sight (Figure 1).
•
Mount detectors at least 6 m (19 ft. 8 in.) apart, and use the
short-range setting to avoid interference.
The dual technology processing of this detector is very resistant to
false alarm hazards. However, avoid potential causes of instability,
such as:
PIR hazards (Figure 1):
•
Direct sunlight on the detector
•
Heat sources within the detector field of view
•
Strong air draughts onto the detector
•
Animals in the field of view
Microwave hazards:
•
Mounting surface susceptible to vibrations
•
Metal surfaces reflecting microwave energy
•
Water movement through plastic pipes
•
Moving or vibrating objects like fans, heating or air-
conditioning ducts

GE Security recommends that the detector is regularly walk tested
and checked at the control panel.
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, 3, and 6).
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 7). See section "Setting the detector" 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 8 for example).
