Controller to Controller with Fiber Optic
Link, Signal Line Circuit Classication
Class B or X per NFPA 72.
Up to twelve EQP controllers (single or
redundant pair) can be inter-connected via
a fiber optic link. This communication link is
classified as a signaling line circuit per NFPA
72 to allow safety information to be transferred
between controllers.
The fiber optic link incorporates media
converters to convert from copper to fiber
optic cable. The converter must be located in
the same cabinet as the controller and cannot
use ground fault monitoring. The approved
supported converters are shown in Table
3-9. The link budget for the listed fiber optic
converters is 10dB.
WARNING
The fiber converters must be mounted
inside the same enclosure as the
controllers to conform to NFPA 72.
