DD669-U • Mount the detector so the expected movement of an
intruder is across the detection pattern.
• 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.
EN: Installation Sheet
The dual technology processing of this detector is very
resistant to false alarm hazards. However, avoid potential
causes of instability, such as:
Description
PIR hazards (Figure 1):
The DD669-U is a dual motion sensors. It has the patented
Range Controlled Radar technology.
• Direct sunlight on the detector
• Heat sources within the detector field of view
Installation guidelines • Strong air draughts onto the detector
• Animals in the field of view
Figure 5 legend • Obscuring the detector field of view with large objects,
such as furniture
Item Description
(1) Floor pattern at mounting heights between 2.5 and 3.0 m
(8 ft. 2 in. and 9 ft. 10 in.)
(2) Floor pattern at mounting heights above 3.0 m (9 ft. 10 in.)
(3) Shaded area is shunted when DIP switch 4 is in On position
(4) An arrow inside the mounting plate and sensor module
indicates the Always Active direction
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
We recommend that the detector is regularly walk tested and
checked at the control panel.
