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
