9.3.2 INSTALLATION OF MULTIPLE SYSTEMS
When two or more 4700 systems are mounted in close proximity and in alignment with each other,
precautions should be taken to avoid one curtain interfering with another. This can be corrected by
mounting the transmitters and receivers back-to-back or stacked. See Figure 9-7 for reference.
