Honeywell FF-SB12 Series Installation Manual page 14

Beam diameter is the smallest width that will block a single light beam. The FF-SB12 and FF-SB14 have a
beam diameter of 9,5 mm (0.37 inch). The combination of the beam diameter and center distance gives the
FF-SB12 (see figure 1-6) a resolution of 22 mm (0.87 inch), the FF-SB14 a resolution of 35 mm
(1.38 inches).
The FF-SB15 has a 235 mm (8.5 inches) gap between the sets of its beams and is considered suitable
for perimeter guarding only.
IMPROPER POINT-OF-OPERATION PROTECTION
Do NOT use FF-SB15 Series light curtains in point-of-operation applications.
Failure to comply with these instructions will result in death or serious injury.

IMPROPER INSTALLATION OF FF-SB SERIES LIGHT CURTAIN
• DO NOT use FF-SB12 or SB14 with FF-SB15 emitters or receivers.
Failure to comply with these instructions could result in death or serious injury.
Protected Height
Protected height is the height from the top of the uppermost light beam to the bottom of the synchronization
beam (see figure 1-5). The synchronization beam is part of the protected height.
Synchronization
The FF-SB Series emitter is optically synchronized by an infrared light beam sent from the receiver to the
emitter. The beam keeps the emitter and receiver in synchronization. External wiring between the emitter
and receiver or through a third control unit is not needed. To simplify maintenance and inventory, the emitter
and receiver are not matched.
