FPA1200 and FPA5000 CAN-bus to Multimode converter, DL-CAN-FPA

The systems DL CAN connects Bosch FPA1200 and FPA5000 Fire Panels via multimode fiber optics to eachother. The ruggedness to electrical and magnetic interferences, the potential separation of transmitter and receiver as well as ranges up to 5km between two fiber optic systems are important performance features of the transmission with multimode fiber optics. LEDs and potential free contacts of a differential relay signalize defective states.
 With ST or SC as optical connection types.

System description
The converter „d-light DL-CAN“ is used to enable CAN connection via fiber-optics. It offers two
separate power inputs for main and backup power. An integrated trouble relay can be used to
display the trouble on the FPA.
DL-CAN/1x13-MM-SC differs from DL-CAN/1x13-MM-ST only through the different type of
connector (“SC” instead of “ST”) and is also suitable. The same applies to the variants for
“single-mode” cable, which were not explicitly tested but based on the test results are deemed
suitable for networking the FPA panels.
Mounting location
If possible the converter should be mounted inside the FPA5000 cabinet or at least in an
adjoining separate housing. In this case the power and data lines between the FPA and
converters are not seen as transmission lines in terms of EN54-13. Additional monitoring of the
power lines can be avoided.
Connection to CAN network
Attention: The fiber-optics converters are only allowed in a CAN loop topology! Use in bus
topologies, i.e. more than one converter in a CAN connection, is forbidden. The only exception
is the connection from the redundant MPC panel controller to the master MPC panel controller.
- The fiber-optics pairs are to be crossed (i.e. RX <-> TX, TX <-> RX)
- Correct termination must be taken into account
Use of „trouble“ relay
In case of trouble, the converter opens the contact K1/K2. In order to register and process the
trouble, these dry contacts can be connected the inputs “IN1” and “IN2” of the panel controller.

FiberView is a monitoring system that has especially been developed to monitor the status of fiber optic paths. It consists of a software/hardware combination which is integrated in all active network components and which permanently monitors the path's budget per port. Three LEDs or - in case of switches - an additional user interface, reachable via web interface, show in terms of a "traffic light" if the fiber has got a good signal level (green LED), if the signal is close to the allowed limit  (yellow LED) or insufficient (red LED). if the yellow LEDs lights up the budget is barely within the defined system reserve of 3dB. Since this warning level is additionally signalled via a potential free relay contact, it can be evaluated centrally in SCADA-systems as well.

In contrast to other status signals that have to be interpreted first, the FiberView "traffic-light" system is clear and generally understandable. Furthermore, the yellow phase allows a foresighted action, i.e. acting instead of reacting. Since the attenuation is not that high at this stage, the fiber optic connection is still working. Maintenance and repair work should, however, be initiated  to prevent any breakdowns. Thus equipments' downtimes are avoided. All in all, a monitoring system like FiberView helps increasing productivity and reducing costs.
