•
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.

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

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.
