EN54:
To make a type J output (output for the activation of a
remote fault-signalling device as required by EN54-2,
[A]
), you must use a remote communication device
which is compliant with EN54-21 regulations
[B]
and
which must have a normally-open supervised activation
input
[C]
, a normally-closed fault signalling output
[D]
and a normally-open output to provide feedback
indicating successful communication
[E]
.
This is done by making the connection illustrated in the
figure, using a relay output (of an IFM24160 module,
IFM4R module or relay module)
[A]
configured as
“communicator fault condition output” and an input of
an I/O module
[F]
configured as “communicator fault
condition input”.
EN54:
To construct a type E output (output for the activation
of a remote alarm-signalling device as required by
EN54-2,
[A]
), you must use a remote communication
device which is compliant with EN54-21 regulations
[B]
and which has a normally-open supervised activation
input
[C]
, a normally-closed fault signalling output
[D]
and a normally-open output to provide feedback
indicating the successful communication
[E]
.

FPMCPU front-plate module wiring - repeater connection
The wiring for the FPMCPU module provides for a connection to the Ethernet network via LAN cable and to the RS485
BUS which must be set up between the Previdia control panel and the system repeaters.
The connection to the Ethernet network is obtained through the LAN port on the module (
paragraph 3.4 - [M]
).
Cables:
UTP cable with RJ45 connectors
Protected by ferrites (supplied)
Compliant with local laws and regulations in force
The BUS connection is achieved through the RS485 communication port on the module PCB (
paragraph 3.4 - [P]
). Two
connection methods are possible, depending on whether the power supplied to the control panel is sufficient enough to
power the repeaters, due to the loads required or the length of the cables.
Cables:
4 wire shielded cable
Maximum length (from control panel to last repeater)
1000m
Protected by ferrites (supplied)
Compliant with local laws and regulations in force
Each connection in the network must be completed in accordance with the instructions in
paragraph 4.6.1
.
