Removing the Old Master
If the existing system is still operational, run a test by playing the radio and testing the
intercom functions to each room, patio and door station. If one or more of the stations do
not function, this could be a sign that there is faulty wiring.
If one of the stations does not function properly, try swapping the defect station with a
working station. If the defective station works in the new location, and the working station
now does not work in it’s new location, this is a sign that there is trouble with the wiring. If
the defective station does not work in the new location, this probably means the station is
defective.
Make sure the power to the existing system is turned off.
Remove the master unit from it’s housing.
If you encountered wiring issues in the operational test above, this would be a good time
to perform and continuity and short test on the existing wiring.
Check to see if the existing wires are marked. There should be wires for each room, patio
and door station, antenna (both AM & FM) and power. If these are not already marked,
place a tag on each wire show what station it goes to or what it is used for. If you are not
sure of the use, the printed circuit board where the wire is connected is normally marked
with connection details.
Once all the wires are marked, you can disconnect all the wires and remove the master
unit from its housing.
With the master removed, the housing should look something like this with all the wires
disconnected and marked.
