Installing External Paging

The CPU provides an External Paging output. You connect the CPU Paging output to audio inputs on cus-
tomer provided Paging systems. Be sure the connected Paging equipment is compatible with the following
page output specifications:
The following products should help if you make your own cables. The connector is generally referred to as a
RJ45 connector wired in an RJ61X configuration. Check with your local supplier for comparable products.
