A-CB4 CONFIGURATION
1. The status output of the A-CB4 can be configured to be triggered by an
external source or to be constantly active. If the status feature is to be
used, both the status selector jumper on the A-CB4 and the status indi-
cator jumper on the A-BUS amplified module should be set to the
"enabled" position. If you do not intend to use the status feature, set the
status selector on the A-CB4 and the status indicator jumper on the A-
BUS amplified module to the "override" position. All A-BUS components
are shipped with the status jumpers set to the "override" position by
default. The status indicator jumper is located on the circuit board of the
A-CB4. See Figure 4 for status indicator jumper settings. See the A-BUS
amplified module’s instructions for status jumper settings.
INSTALLATION
1) Check all connections, and proper system operation before installing the
A-CB4 into the wall.
2) Using the included hardware, install the IRB-5 into a standard UL/CSA
electrical J-box as shown in Figure 6.
