1.7 Relay output - Fault Annunciation
TB6 on the NION-SPB board is used to annunciate a
trouble condition; Normally Open and Normally Closed
contacts are available. The trouble relay will activate
when the VGM NION cannot communicate with either
the VGM or the Echelon server.
1.6 NION Power Requirements
The NION-SPB re24VDC @ 250 mA nominal and battery backup in accordance with local code require-
ments. It can be powered by any power limited source that is UL listed for use with fire protective signaling units.
The NION is equipped with a +3VDC lithium battery for data backup during low power conditions. The VGM
NION is powered by ex24VDC supply at TB5.

1.8 SMX Network Connection
The UniNet™ facilities monitoring system is distributed via a LonWorks™ network. This high-speed network allows
communication between field nodes and a Local Area Server or a BCI. NION modules provide the communica-
tion links between monitored equipment and the network.
J1 SMX Connection
A twisted pair of wires is used for data transmission between a Vista Gateway Module and the VGM NION con-
necting to the UniNet™ network. The FTXC transceiver is used for FT-10 (Free Topology) wire bus and star
network configurations.
The wire must be twisted pair cable, UL listed for use in a power-limited fire-detection system (if used in conjunction
with a fire monitoring network), and riser, plenum, or non-plenum cable, according to local fire alarm wiring
codes.
NOTES: Use only wire for power limited systems. Power limited wire runs use type FPLR,
FPLP, FPL or equivalent cabling per NEC 760.
NOTE: All non-fiber network connections are transformer isolated making all network
communication immune to ground fault conditions. Therefore, no ground fault supervision of
the Echelon network is required or provided.
