Installing Control Carrier Outputs Cable
Control carrier outputs are used for power failure transfer power, accessory power (not
provided on System 75 XE), alarm monitoring, customer provided alarm (System 75 XE
only), and the Initialization and Administration System (INADS) interface. A 25-pair
switch cable connects the control carrier AUXILIARY connector (see Figure 2-46 or 2-47) to
the 1C connector on the first (top) cable access panel.
Figure 2-35 shows the 1C terminal row designation label required at the cable access panel.
These outputs must be distributed to other points and do not pass directly through the cable
access panel. To connect the cable, do the following:
1 .
Remove all straps between the 1C and 1D terminal strips on the initial (top) cable
access panel only.
2 .
Install a YELLOW auxiliary label on both connector ends of a switch cable. The
letters "AUX" should be written on each label.
3 .
Run and connect switch cable from AUXILIARY connector on rear of control
carrier through cable slack manager to 1C connector on cable access panel.
The output wiring connections for alarm monitoring, emergency power failure, accessory
power, and the INADS trunk interface is contained in this manual under the heading
MISCELLANEOUS WIRING INSTALLATION.
