Installation
N OTE : All system line balancing is located in this cabinet; therefore, any existing page and party line
balance assemblies must be removed when the Model MI05-101 Merge/Isolate Cabinet is installed.
Cabinet Mounting
Mount the M/I cabinet in a secure area that is protected from adverse environmental conditions such as
rain, heavy dust, excess moisture, and temperature extremes. For optimum performance, mount the
cabinet no farther than one mile from the farthest Page/Party
® station. Mount the enclosure to the wall by
installing four mounting bolts through the predrilled holes in the rear of the enclosure.
Field Wiring
All terminations are made to the Termination PCBA using modular terminal block connections. Each
connection is labeled inside the M/I cabinet.
Connecting Field Stations
1. Locate the Termination PCBA in the lower left corner of the cabinet. See Figure 2.
2. Connect all page and party lines from each of the zones to the appropriate terminals on the
Termination PCBA. GAI-Tronics 60038 Series single party cable or 60029 Series multi-party cable
is recommended.
