Replacing Modules in a 2-Slot Carrier
!
WARNING:
!
Before starting, verify that you have batteries installed in the PARTNER ACS 
processor module, and then disconnect the power cord from the power jack on 
the carrier. For an illustration showing the location of the power jack, see 
“Initializing the System”
earlier in this guide.
1 Check the slack in the wires. If 
there is not enough slack to 
remove the modules without 
pulling the line and extension 
cords free, label and disconnect 
the wires before continuing. 
2 Remove the long screw at the 
bottom of the modules. 
3 Remove the screws that attach 
the carrier to the modules.
