2-1 F3SS System Specifications
The F3SS is a long-range, single-beam infrared safety control designed for perimeter and access guarding. In-
terruption of the beam sends a stop signal to the guarded machine. A “redundant” microprocessor design com-
bined with extensive fault mode and effects analysis provides safe, control reliable operation.
A F3SS system consists of one emitter and one receiver. No interconnecting cables or separate control enclo-
sure are required. Maximum distance between emitter and receiver is 60 m(200 ft.).
