EN: Installation Sheet
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
•
Obscuring the detector field of view with large objects,
such as furniture
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
WARNING!
The equipment is not earthed. Any
external circuit connected to the equipment must be
located within the same building and connected to a
protective earthing conductor.
Wire insulation of cables connected to the equipment must
conform to IEC 60332-1-2 and IEC 60332-1-3 or IEC 60332-
2-2, depending on the wire cross sectional area, or IEC TS
60695-11-21, regardless of cross sectional area. Alternatively,
such wires must comply with UL 2556 VW-1.
The detector power supply source must be power limited at
15 W.
We recommend 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.
The detection pattern can be adjusted by up to ±15°
3.
(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.
