Override Input
The Override is a feature that lets the caller take priority over all other paging functions and make a page.
The center tw
o conductors interface directly to a Loop Start Trunk or a dedicated phone.When the trunk becomes
active, the UTI3
12 goes into Override mode. A contact closure and dry audio source can also be used for the
Ov
erride Input. The two conductors flanking the talk battery conductors provide a dry audio gateway into the
system override. Override is activated by shorting the outermost conductors.
Maximum contact closure resistance is 1000 ohms. Open collector type outputs for controlling a page may also be
used.
The Override feature includes a quad beep pre-announce tone that can be enabled or disabled. (The default
is enabled.) Make sure that the power is disconnected and all other connections are completed before proceeding.
Plug modular cord into OVERRIDE (RJ11) jack.
90V Night Ring Input
The 90V Night Ring Input connects to an analog station line from the PBX or directly to a central office phone line.
The UTI312 will follow the incoming ring signal cadence with a simulated ring or chime tone to the Night Ring zone
group.
Note: The Night Ring feature has priority just above background music.There is a 5-second delay after the night ring stops before
background music is restored (to bridge inter-ring pause).
