PIR Termination
If PIRs are being used on the site, then their detection curtain must be terminated suitably, in a
similar fashion to blocking out lights from nearby roads. Referring to Figure 15 under the PIR
alignment section, the detection curtain should be terminated by a suitable material at the
boundary of detection. Suitable materials include privacy mesh that can be woven into chain link
fences, plywood, heavy landscaping cloth or plastic facades. The use of steel is not
recommended, as it may heat to a temperature that a PIR may incorrectly detect as a human
body.
