FF-SB12, 14 and 30 Mounting
Two emitter/receiver units may be mounted together to obtain a greater protected height (see
figure 2-10). Mount the units head-to-head so the synchronization beams are as far apart as
possible. Mount the emitter/receiver units in a reverse transmitting position to prevent mutual
interference or cross-talk. The units may be mounted with the over-lapping heads to maintain
the resolution throughout the protected height.
