5 Perform Settings & Adjustments SET THE DETECTION LENGTH Note: The length of the lower detection area determines the detection length. The upper detection area stays parallel to the ground at all times. The lower detection area can be adjusted by the Detection Length Adjustment Switch as shown below. Detection length is therefore limited by the length of the lower detection area since both upper and lower areas have to be blocked at the same time to activate the sensor. IMPORTANT: This sensor detects temperature differences between the moving object and the background temperature in the detection area to produce a valid detection. If the object does not move, the sensor will not detect it. If there is traffic near the detection area, adjust the detection area length 1.5 to 2.0m (5 to 7ft) back from traffic. Detection Length Detection Length Detection Length UPPER and LOWER beams are blocked, detection is made. Only the LOWER beam is blocked, detection is not made. Press and slide the Detection Length Adjustment Switch to the desired position. Default Setting D C B A DETECTION LENGTH D 02.0m (6.7ft) C 05.0m (16.7ft) B 08.0m (26.7ft) A 12.0m (40.0ft) NOTES: • This table is based on a motion sensor height of 1m (3.3ft) • The height of the motion sensor will effect the detection length. In addition, the detection length may vary due to environmental conditions. Only the UPPER beam is blocked, detection is not made.
