PIR sensor information
PIR (PASSIVE INFRA RED) SENSOR:
The fitting has a PIR (Passive Infra Red) sensing device which continuously scans the operating zone and immediately
switches the light on when it detects movement in that area. Whenever movement is detected within the range of the
sensor, the light will switch on automatically to illuminate the area. While there is movement within the sensor range,
the light will remain on.
SENSOR LOCATION & INFORMATION:
To find a suitable location for installation, please take into consideration the following points:
• The ideal mounting height for the fitting is between 1.8m to 2.5m above the detection area (figure 1).
• The detection area is approximately 8 metres away at an angle of 100° wide. This may vary depending on the
mounting height and location.
• The detection area may also alter at different temperatures. PIR sensors are more sensitive in cold weather than
warm weather.
• The sensor has better sensitivity with movement across the detection area (figure 2).
• The sensor has reduced sensitivity with movement towards and away from the detection area (figure 3).
• If movement is made walking directly towards or away from the sensor and not across, the apparent detection
range will be substantially reduced.
• To avoid false triggering, the sensor should be directed away from potential heat sources, such as barbecues, air-
conditioners, air vent etc.
• Also avoid areas with electromagnetic disturbance, outside lighting, moving cars, trees or pets etc.
• Avoid installing the fitting in close proximity or on the same circuit to any fluorescent light fittings or ceiling fans.
RFI (Radio Frequency Interference) may cause the fitting to switch on unintentionally.
• Do not aim the sensor towards reflective surfaces, such as smooth white walls, swimming pools etc.
• To avoid damage to the sensor, do not aim the sensor towards the sun.
• It is recommended that the fitting is installed on its own switch and does not interconnect with other lights on the
same switch as it may cause false triggering.
