C-18 IMACS System Release 5.1.9 Reference Guide
Model No.
Running Head
The INF card uses faceplate connectors that are electrically similar to those of the INF-E and
INF+M cards previously described. The only exception is that the NODE jack of the INF card
serves two purposes. It provides alarm relay contacts for external activation, and also provides
data and clock interfaces for external alarm reporting systems.
Connect the INF card to the external local terminal, alarm reporting system or printer, and
T1/E1 network, as previously described for the other Interface cards. Also connect the alarm
relay contacts and synchronization clocks to the NODE jack. Table C-12 lists the signal
pinouts for that jack.
Using the RS-485 Node Port
The RS-485 Node port allows you to activate external alarms that alert on-site personnel to
critical situations. Using the ACO function will keep the alarm active until it is manually
cleared form a control terminal.
Connect the NODE jack of the INF card to the external alarm equipment. This is another
RJ-48 jack; it provides a set of form-C relay contacts to the external alarm equipment. Figure
C-15 shows the pin locations on this jack, which are the same as the COM2 jack. Table C-12
lists the associated signal pinouts.
