Procedure 2-6
Installing an Alarm Cable (Optional)
Step Action
1 Route the alarm cable for the 3930 so that it can extend from the ALARMS
connector on the faceplate, then to the left across the front of the chassis,
through the cable management bracket, down the frame and over to the wire
wrap panel.
Note: Do not actually plug the alarm cable into the ALARMS port until after
the cable has been trimmed and connected to the wire wrap panel. However,
when you are routing the cable, ensure there is sufficient slack to properly
connect the cable to the faceplate when asked to do so.
2 Using local practices, trim the cable to the desired length and connect the
alarm sense and return leads to the wire wrap panel for each alarm being
connected to the system. The alarm pinout is provided in Table 2-2 on page
2-12.
3 Plug the 26-pin D-sub connector into the connector on the faceplate of the
3930 labeled ALARMS. Using a Phillips screwdriver to secure the captive
screws on either side of the connector.
4 If desired, use a cable tie to secure the alarm cable to the cable support
bracket or frame to further assist with cable retention.
You have now installed the Alarm Cable.
