SYSTEM AND METHOD FOR FIBER OPTIC COMMUNICATION WITH SAFETY-RELATED ALARM SYSTEMS

摘要

A system and method for monitoring and safety related systems (SRSs) in a Secure Compartmented Information Facility (SCIF) that addresses concerns for security of electronic emanations from equipment in the SCIF. A fiber optic link (125) connects an optical receiver (130) located within a SCIF and an optical transmitter located outside the SCIF. Alarm signals generated by an SRS located outside the SCIF are detected and sent to the optical receiver (130) over the fiber optic link (125) and directs the signals to alarm devices (155) within the SCIF. The optical receiver (130) located within the SCIFF monitors an alarm device (155) within the SCIF for the presence of an alarm condition within the SCIF. If an alarm condition within the SCIF is detected, an alarm signal is sent over the fiber optic link (125) to the optical transmitter (100) located outside the SCIF and directed to the SRS located outside the SCIF.
