P/N 146279999-2 (ML) • REV H • ISS 11MAR19 3 / 36
EN: Installation Sheet
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.
Note: Only VE1120 has 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
• Installing two detectors facing each other and less than
50 cm (20 in.) apart (only AM detectors)
Installing the detector
