Beam Patterns for Lenses BV-L1 to BV-L4

Locating the Detector

Select a detector location that will provide the coverage required keeping in mind the 
following potential problems.

• Do not aim the detector at 

reflective surfaces 

such as mirrors or windows as this 

may distort the coverage pattern or reflect sunlight directly onto the detector.

• Avoid locations that are subject to direct high 

air flow 

such as near an air duct out-

let.

• Do not locate the detector near sources of 

moisture

 (steam or oil).

• Do not aim the detector such that it will receive direct or reflected (mirror) 

sunlight

.

• Do not limit the coverage by large 

obstructions 

within the detection area such as 

plants or filing cabinets.

• When using BV-L4 (Pet Alley lens): Do not aim the detector at a stairway which a pet 

has access to. Do not place furniture or objects higher than 3 ft/0.9 m, which a pet 
can climb onto (e.g. a cat on a couch), closer than 6 ft/1.8 m to the detector.
