Installing External Paging
The CPU provides an External Paging output and associated relay contacts.
You connect the Paging output to audio inputs on customer-provided Pag-
ing systems.
To connect an External Paging amplifier:
1. Find an available connector in a station cable and make sure it is cor-
rectly punched down at the 66M1-50 block.
Follow standard color code order. Be sure the block is properly
cross-connected.
2. For the connector chosen, locate pins 1T and 1R (see below) and connect
the music source.
3. Plug the modular jack into the CPU modular connector.
Be sure the connected Paging equipment is compatible with the fol-
lowing CPU page output specifications:
Output Impedance:
600 Ohms
Output Level:
0 dBr @ 1.0 kHz
The following products should help if you make your own cables:
