AUDIO PAGE PORT INSTALLATION INSTRUCTIONS:
The ZC-312 can be connected to an audio page port only if the audio page port provides:
(A) A 600 ohm, low power page output, capable of passing DC loop current.
(B) Transmission of DTMF touch tone, or rotary dial pulses.
(C) A dry contact that is normally open, closes when paging and reopens when the page is completed.
If these conditions are met, then connect Tip and Ring as shown in Figure 12.
