Viking PA-250 Product Manual page 12

I. VOX Silence Time Out
For the AUX INPUT and when the VOX mode is used for either Mic paging or Paging Port paging on the PAGE INPUT,
the length of silence time required to end the page can be programmed from 1 – 9 seconds. The factory set time is 3
seconds, which means the page will end when no audio has been detected for 3 seconds.
To program VOX Silence Time Out, enter a single digit 1 to 9 then #49 in programming.
J. Telecom Silence Time Out
For either the FXO (Loop Start) or FXS (Ring Trip) modes on the PAGE INPUT, a silence time (from 1 – 9 seconds),
can be programmed to end the page. The PA-250 is factory set with the Telecom Silence Time Out disabled.
FXO (Loop Start) paging will instantly end when the phone or Trunk Port hangs-up. If there is a potential risk of that not
happening, the Telecom Silence Time Out can be used as a safety net to end the page.
FXS (Ring Trip) paging requires some sort of signaling from the phone system that the distant phone has hung up. The
PA-250 will hang up when it detects a CPC momentary open loop signal, (if the system provides it). If a CPC signal is
not provided, but the system either returns to dial tone or a busy signal, the Return to Dial Tone Detection or Busy
Detect feature should be enabled for the PA-250 to be able to drop the page. If the system does not provide any of
those, this Telecom Silence Time Out feature needs to be used. The page will simply end after the programmed amount
of silence.
To program Telecom Silence Time Out, enter a single digit 1 to 9 then #50 in programming.
Telecom Silence Time Out can be manually disabled by entering just #50 in programming.
K. Chime Tone
One of four different sounds can be programmed for
the Chime Tone that happens when a momentary
contact closure is detected on the CHIME TRIG
input. Program as shown right.
L. Pre-Page Alert Tone
A short beep tone can be generated at the beginning of a MIC or Telecom page to help call attention to the upcoming
announcement. This Pre-Page Alert Tone can be enabled and disabled in programming.
To disable the Pre-Page Alert Tone enter Q0 in programming.
To enable the Pre-Page Alert Tone enter Q1 in programming(Factory Setting).
Note: If the page is initiated by VOX control, the Pre-Page Tone will not be generated so it does not beep on top of the
voice page.
M. Busy Detect and Return to Dial Tone Detection
FXS (Ring Trip) paging requires some sort of signaling from the phone system that the distant phone has hung up. The
PA-250 will hang up when it detects a CPC momentary open loop signal, (if the system provides it). If a CPC signal is
not provided, but the system either returns to dial tone or a busy signal, the Return to Dial Tone Detection or Busy
Detect feature should be enabled for the PA-250 to be able to drop the page. If the system does not provide any of
those, the Telecom Silence Time Out feature needs to be used. (See Programming Section J).
To disable the Busy Detect feature enter Q4 in programming (Factory Setting).
To enable the Busy Detect feature enter Q5 in programming.
To disable the Return to Dial Tone feature enter Q6 in programming (Factory Setting).
To enable the Return to Dial Tone feature enter Q7 in programming.
IMPORTANT: The front panel PAGE volume control needs to be turned up enough that Dial Tone or Busy signal brightly
light up the PAGE LED
