Alone Telephone or Unused CO Port Wiring
If a stand-alone telephone or an unused CO port on a telephone system is used, wire the Tip and Ring
wires directly to the
PHONE IN terminals. The Tip wire is usually green and the Ring wire is usually
red. See Figure 6 for the location of the connection on the SP4-TZC.

2.4.3.2 Audio Page Port Wiring
If the SP4-TZC is to be connected to an audio page port, the Audio Page Port must provide:
(A) A 600 Ohm, low power page output, capable of passing DC loop current.
(B) Transmission of DTMF tones (touch-tone).
(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 7.
