15. AUDIO PAGE PORT INSTALLATION INSTRUCTIONS:
The MZC-144 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.
(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 13.

16. NIGHT RINGER INSTALLATION INSTRUCTIONS:
The Night Ringer works from a dry contact closure through which no more than 10mA of current will be drawn. The dry
contact closure will result in the Night Ringer function, an All Call will occur and the alert tone sent out. The alert tone will
remain until the dry contact closure opens. This feature will follow the dry contact closure presented between the Night Ring
and GND (TB3 Pos. 7 and 8). This feature has a lower priority than paging. Therefore if a page comes in while the Night
Ringer is active, the page will take priority.
