Description
The VE1120 series includes:
•
VE1120 PIR motion sensor
•
VE1120AM PIR motion sensor with anti-masking
They have a patented mirror, pyro, and signal processing
technology.
Installation guidelines
The technology used in these detectors resists false alarm
hazards. However, avoid potential causes of instability (see
Figure 1) such as:
•
Direct sunlight on the detector
•
Strong draughts onto the detector
•
Heat sources within the detector field of view
•
Animals within the detector field of view
•
Obscuring the detector field of view with large objects,
such as furniture

•
Objects within 50 cm (20 in.) of the anti-masking (AM)
detector
•
Installing two detectors facing each other and less than
50 cm (20 in.) apart (only AM detectors)
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.
