Expansion Card Description Illustration
Relay Card
Refer to Figure 2-34 in
Chapter 2, “Installation”
for a wiring diagram for
Relay outputs.
Adding a Relay Card expands the number of available
programmable relays. The Relay Expansion Card is
equipped with four Form C floating relay contacts.
Each relay is independently-driven and can be pre-
programmed to change state for all states of Alarm,
Trouble and Supervisory conditions. Red and green/
yellow status LEDs are visible from the outside edge
of the module. The ability to isolate an individual
relay output is provided through the system menu.
The relays are normally de-energized, unless
configured for Trouble. A Trouble relay is energized
upon startup and changes state for any Trouble
event, including failure of the Main Controller Board.
Ratings are as follows:
•3 A at 30 Vdc
•3 A at 120 Vac
The Relay Expansion Card occupies a single slot in
the Expansion Card Cage Assembly and plugs
directly into the backplane. +24 Vdc power is
supplied via the backplane connector.
There is no limit on the number of Relay Expansion
Cards which may be included in a FenwalNET 8000-
ML system (dependent only on how many slots are
available in the Expansion Card Cage(s).
City Tie Card
Refer to Figure 2-35 in
Chapter 2, “Installation”
for a wiring diagram for
the City Tie Card.
The City Tie Expansion Card provides connection and
operation for three independently-operated signaling
circuits used to connect to Municipal Tie inputs:
• Local Energy output
• Shunt-Type Master Box output
The City Tie Expansion Card occupies a single slot in
the Card Cage Assembly and plugs directly into the
backplane. +24 Vdc power is supplied via the
backplane connector.
A FenwalNET 8000-ML system can include only one
City Tie Expansion Card per node.
