FMD 2001 and FMD 2012 stations must be connected to the 'EMERGENCY UNITS' of the VAIE 2250 system. It
is possible to connect up to 7 remote stations in cascade formation by means of the IN/OUT (10) sockets
provided for this purpose, which can be used as inputs or outputs as required. Special attention must be paid to
assigning correctly the logical addresses to each station (see point 4.1, "Address", page 19).
The connections to the stations are made by means of CAT5e SF/UTP shielded cable and a shielded STP connector.
For these cables EIA/TIA T568A and EIA/TIA T568B (and the associated RJ45 connectors) standards require the
pinouts and colour schemes shown in the table:

The table also shows the pinouts for the IN/OUT
connectors (10).
N.B.!
Cross-cables are not permitted.
All the connectors must be shielded RJ45
connectors.

Sizing
Using shielded CAT5e SF/UTP cable, it is possible to apply the following limits:
1 station = total length max 300m
2 stations = total length max 200m
3 stations = total length max 100m
For systems with more than 3 stations connected to them, at distances greater than those indicated above, each
station will also have a local power supply providing a continuous stabilised current of 24V
socket provided for this purpose on the rear (9).
