3. Mounting Components
The sensors should be installed securely using the mounting brackets supplied with sensor “A” closest
to the entry (mounting screws not supplied). The sensors should be mounted at a level that people will
break the beam. They are most effective when mounted about 3-4ft above the ground (aim at the torso
section), or 4-5ft to ignore children in counts.
Plan to mount the reflectors directly across from the sensors at a distance no greater than 5 meters
(16ft). DO NOT MOUNT THE REFLECTORS UNTIL STEP 4. Make sure nothing is in the path
between the sensors and reflectors. Before mounting the reflectors make sure that the sensor-reflector
alignment is correct (see step 4). Mounting suggestions are located in figure 4.
The Count Recorder can be mounted or set in any convenient dry location. For more system layout
suggestions refer to the Count Recorder manual.
4. Aligning and Mounting Reflectors
After the sensor and count recorder are wired and mounted, connect the power supply to a 120V AC
outlet and take note of the lights on the sensor. Focus your attention on the yellow light. The yellow
light on sensor B should be ON without a reflector in front of the sensor. With nothing blocking the path
between the sensors and reflectors proceed as follows:
1. Align the first reflector with sensor “B” by placing it directly across the sensor and adjusting it until
the yellow light is OFF on sensor “B” (the green light may or may not be on). If the yellow light is
illuminated then either the sensor and reflector are not aligned or something is in the path of the
beam from the sensor to the reflector. Further adjustments to the sensor alignment can be
accomplished by loosening the screws on the sensor bracket in order to point the sensor up or
down or side to side.
2. If the opening is less than 5ft, the yellow light on sensor “A” should be OFF. Proceed to step 4.
3. If the opening is greater than 5ft, the yellow light on sensor “A” should be ON. After the reflector
is aligned with sensor “B,” align the second reflector with sensor “A” in the same way. Once
aligned properly the yellow light will NOT be illuminated. When the beam is broken, the yellow
light will illuminate and the count will be incremented by +1.
4. Mount the reflector(s) at the appropriate location securely using screws or heavy duty, double-
sided, foam mounting tape and tighten the screws on the sensor brackets in order to maintain
alignment.
NOTE: The Photoelectric sensors include adjustments for both sensitivity and signal delay located under
the sensor cover. These settings are factory set and should not require adjustment. If
adjustment becomes necessary due to unforeseen conditions, the time delay or sensitivity can
be increased or decreased on sensor “B” only by rotating the appropriate adjustment using the
small blue screwdriver provided. Turning clockwise will increase and counterclockwise will
decrease. DO NOT MAKE ANY ADJUSTMENTS TO SENSOR “A.” Increasing the time delay
will reduce false signals but slow the operation of the sensor.
