Replacing a CXCI Controller
1.
Write down the CXC communication information: dynamic or static IP, IP address, and gateway.
2.
Connect a laptop to CXC per software manual; standard network crossover cable to Ethernet port.
3.
Save the CXC configuration file (see software manual
Logs and Files > Manage Configuration File > Save
Full Site Configuration
).
4.
Save the CXC text file if necessary:

.
5.
If applicable, bypass the system LVD:
•
Locate JP2 on the back of CXCI system shelf (Figure 15)
•
If the LVD is controlled on NC contacts (factory default for LVD option), then JP2 pins 1 and 2 must
be shorted together to maintain LVD operation.
•
If the LVD is controlled on NO contacts, then JP2 pins 2 and 3 must be shorted together.
NOTE
: bypassing the LVD generates an alarm.
