Impairment of system function
● Pay attention to the Ethernet cable connection if you are connecting more
than one PMI & mainboard.
Never connect a port P1…P4 to a port P1…P4.

The detector contact is normally wired on a free I/O connection of the periphery
board. If all connections are occupied or if using the FT724 fire terminal, the
detector contact must be connected via an I/O module (e.g. an FDCIO222). In this
instance, the signal of the I/O module must not be configured as 'Degraded alarm
relevant'.
If a station is located very close to the FT724 fire terminal, the detector contact can
also be wired directly to this station.

The parallel resistor for the detector contact depends on the I/O module used.
Refer to the documentation provided with the I/O module used for more details.

Use of the redundant L2+/M2 supply inputs is optional and not necessary for EN-
54 compatibility.
