Optical Alignment

To ensure optimum operation, the proper optical alignment of the FF-SPS4 Series perimeter
guarding devices is essential. The emitter and receiver devices must be mounted in parallel,
at the same height, and with an angular displacement of no more than +2
Figure 2-5 Emitter and Receiver Optical Alignment

Side by Side or Multiple System Installation

To prevent mutual interference or cross talk, pointing emitters in opposite directions may be
necessary in side-by-side or multiple system installations to ensure proper operation.
If two or more FF-SPS4 safety perimeter systems are installed, optical interference may occur
if a receiver receives signals from two emitter devices. This condition may occur due to the
± 2° effective aperture angle of the emitter/receiver and the nominal scanning range (up to
75 m [246 ft]). To provide side protection, point the emitters in opposite directions (see figure
2-6).
