Masking
The EBDHS-MB-DNET1 includes two clip-on masking shields to allow for precise masking of the detection shape.
The masks can be easily shaped to produce detection patterns suitable for applications such as aisles and corners and
for narrowing the detection diameter.
Important note. Ensure all infra-red (IR) programming is completed before affixing the masking shields to the
detector.
The masking shields may impair the light sensor and IR sensors by covering them. Ensure
correct operation before completing commissioning.
