u Redundant network connection

u Indicators for power and fault status

Most of the Praesideo system units have plastic fiber
optic interfaces. Plastic fiber is used to interconnect
nodes which are less than 50 meters apart. For
distances of more than 50 meters, glass fiber optic
cable is used. A fiber interface converts from plastic to
glass fiber, and vice versa. The fiber interfaces have a
power supply input to provide power to remote
network sections, and two control inputs. The control
inputs can pass on supervision information about the
power supply connected to the fiber interface.

Functions

These units interface glass fiber optical cable with
plastic fiber optical cable, and support redundant
wiring topology. In many applications this is necessary,
because glass fiber can bridge much longer distances
than plastic fiber. Any conversion to glass fiber must
be converted back to plastic fiber before other
Praesideo units can be attached, since they all have
plastic fiber interfaces. This means that these units are
always used in pairs.
Each interface can use an external 48 VDC power
supply to provide power for itself, as well as for
remote parts of the network. If there is no external
power source, the interface uses power from the

u Can use a local power supply

network controller. The PRS‑FIN and PRS‑FINS have
two control inputs. These can be used to accept e.g.
the fault output of the external power supply (UPS),
allowing the units to monitor the power supply and
report faults to the network controller. The fiber
interfaces have two LEDs for diagnostic purposes.

The PRS‑FINNA is the same as the PRS‑FIN except that
it has no network node address. This has the
advantage that the unit does not occupy one of the 60
possible addresses in the network. It also has the
disadvantage that without an address, it is not
possible to access the status of the two control
inputs, as it is with the PRS‑FIN.

The PRS‑FINS is the same as the PRS‑FIN, except that
it accepts single‑mode glass optical fiber instead of
multi‑mode glass optical fiber. However, this does not
increase the maximum permitted cable length of a
Praesideo network.

Installation/configuration notes

The PRS‑FINNA and the PRS‑FIN are often used in
combination. The PRS‑FINNA is placed in the local
(POF) network, and connected to a (remote) PRS‑FIN,
which can then provide remote monitoring.
The PRS‑FINS is mostly used in installations where
single‑mode (mono‑mode) glass fiber is already
present. Otherwise multi‑mode glass fiber is a cheaper
alternative.
