Introduction
The VE1120 series includes the VE1120 PIR and VE1120AM
PIR-AM motion sensors. They have a patented mirror, pyro,
and signal processing technology.
Note:
VE1120AM has not been evaluated by UL/cUL.
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
