This document provides a methodology and test procedures to be able to declare and verify the detection area for motion detectors using Passive Infra-Red technology in switches and appliance switches whether stand-alone (direct control of one or more applications) or connected to home and building electronic systems or building automation control systems (HBES/BACS) infrastructure/networks or similar. It also provides a uniform way to present the test results. The purpose of these detectors is to detect the major and minor movements of persons. Detectors may have the added aim of measuring a level of ambient natural light with respect to a reference level and triggering a number of other functions. Safety and EMC requirements are not covered by this document.
