Installing the CX9200

For detailed information on how to mount and connect the wiring to the
CX9200 and it's peripherals, refer to the following Andover Controls
documentation:
Infinity CX9200 Hardware Installation Guide (P/N 30-3001-347)
Energylink 2500 Installation Guide (P/N 30-3001-393)
DCX250 Installation Guide (P/N 30-3001-196)
Infinity Modem Guide (P/N 30-3001-404)

Cable Limitations

• The RS-232 cable between the CX9200 and the FSCS must be no
longer than 20 feet, and must be enclosed in conduit.
• The RS-232 cable between the CX9200 and the Fire Panel must be
no longer than 20 feet, and must be enclosed in conduit.

Comm Port Assignments

In a smoke control system, it is recommended that you use the following
Comm Port assignments:
• COMM1 – FSCS panel RS-232
• COMM2 – Infinet Network
• COMM3 – User terminal
• COMM4 – Fire Panel RS-232

Isolating Energynet Controllers

In a system that performs smoke control, the CX9200s have to be
electrically isolated from other Energynet devices using the Energylink
2500 and the ENL2503 fiber optic module. This is done in order to
ensure that a fault on one of these devices will not interfere with the
operation of the smoke control system. The Energylink 2500 is only
required when connecting CX9200s to other Energynet devices, it is not
required between CX9200s.
The Energylink 2500 mounts in the CX9200 cabinet and receives it's
power from the CX9200 power supply.
Figure 3-1 shows the use of the Energylink 2500 to isolate the CX9200
from other Energynet controllers.
