Motion and presence
detectors
Mounting guidelines for motion and presence
detectors in a room
• Do not expose motion detectors to direct sunlight
• Do not mount any lamps within the detection zone
• Avoid placing any sources of rapid temperature changes
within the detection zone, e.g. air vents,
fan heaters or incandescent and halogen lamps
• Ensure that the direction of air flows moves laterally
to the detection zone
• Detection depends on the temperature difference
between the surrounding ambient zone and the object
to be detected
• The detection zone of a presence detector should not
be impeded or blocked by shelves, plants or glass walls
• Minimum distance of 50 cm from cables and radiators
Mounting guidelines for motion detectors
on a building
• Do not mount motion detectors on moving supports,
such as poles
• In outdoor applications, mount presence detectors
on stable walls
• The detection range of a presence detector should
be free of interferences
