Best Practices

Consider the following when selecting & installing motion sensors:


Create zones controlled by different motion sensors to manage lighting in large areas

Use PIR or HF with microphone dual technology sensors for areas with very low motion activity levels


Educate occupants about the motion sensors and what to expect


Position motion sensors above or close to the main areas of activity in a space


Integrate motion sensor use with other control methods (i.e. time scheduled control, daylighting)


Use HF motion sensors if installation needs to be above a ceiling, behind drywall, or inside a wooden or plastic box


Adhere to electrical specifications noted in owner’s manual and local & national electrical codes



Don’t install motion sensors on vibrating or unstable surfaces as it can create false readings
Don’t use PIR motion sensors in spaces where there are fixtures or furniture that obstruct a clear line of sight
Don’t install PIR motion sensors so that their line of sight continue past adjacent doorways
Don’t install motion sensors within 2m of climate control devices (such as air conditioning ducting, electric heaters, open doors/windows etc). Hot or cold draughts can create false readings
Don’t position a PIR motion sensor behind an office door, above a ceiling or behind a metal panel or wall
Don’t control emergency or exit lighting with motion sensors
Don't install a HF motion sensor behind a metal panel or metal door
Don't mount near open windows or doors
