Paging Interface

Totally Eliminate Paging Feedback
Even the best designed paging systems can
experience feedback. Now you can eliminate
annoying feedback over your paging speak-
ers with Viking’s model SP393 digital
antifeedback paging interface.
The SP393 utilizes state of the art digital
recording technology to record the “live” page
from a phone system’s paging port output or
unused trunk port. The SP393 then immedi-
ately plays back the recorded page once or
twice (selectable) over the paging syostem.
Pages of up to 60 seconds can be stored and the SP393 automatically adjusts to the
page length for faster processing. In addition, the SP393 can be programmed to pro-
vide pre-page and post-page alert tones.

A. Mode Switch
In the Trunk Port position, 24V talk battery is supplied for connecting the SP393 paging input to a phone system’s unused trunk port.
In the Paging Port position, a 600 ohm audio input is supplied for connecting to a phone system’s paging port output.

B. VOX Sensitivity
If the SP393 is installed on a phone system’s paging port that does not supply a page control contact (normally open relay contact
that closes while the paging port is activated) the VOX (Voice Operated Recording) feature may be used. The VOX sensitivity may
require adjustment. Rotate the POT clockwise to increase the sensitivity for low level input signals (see Programming section I).
Note: The VOX (Voice Operated Recording) feature is not used in the trunk mode or when a page control contact is connected to
the record page input of the SP393 to trigger the recording. In these applications, set the VOX sensitivity to the minimum level.

D. Paging Control Output
If required, these optional relay contacts can control your paging system.
The contacts will activate during page playback.
E. Cancel Page Input
The SP393 is capable of cancelling a page in progress. Connect the Cancel Page input to a normally open remote switch or button
at the receptionist’s desk. Momentarily pressing the button will cancel the page in progress (during recording or playback).
F. Record Page Input
Connect the Record Page Input to the normally open paging control contact of your phone system. Place the VOX sensitivity POT
in the “MIN” position. The SP393 will record the page while the contact closure is maintained.
Note: Using the Record Page Input is preferred over using the VOX circuit to control recording.
G. Page Alert Tone Volume
The SP393 has a POT for adjusting pre-page and post-page
alert tone levels (see diagram, right).
H. Paging Volume
Rotate the Paging Volume POT clockwise to increase the pag-
ing volume and counter-clockwise to decrease the paging vol-
ume (see diagram, right).
I. Page LED
This is a recording and playback indicator. When recording in
the Trunk Port mode, the LED will light steady while the phone
system’s trunk port is accessed. When recording in the Paging
Port mode, the LED can be used as a maximum VOX sensitiv-
ity adjustment indicator; the LED should flash only when the
paging port is accessed and paging audio is present, if the LED
lights steady when the paging port is not accessed, the VOX
sensitivity is set too high and should be decreased until the
LED turns off (see Programming section B).
During playback in either mode, the LED will light steady for the
entire duration of the message playback.

A. Trunk Port Mode
Important: The MODE SWITCH must be in the TRUNK PORT position.
1. Access the phone system’s trunk port that is interfaced to the SP393.
2. Announce the page.
3. Hang-up.
Note: The SP393 will record the entire time the trunk port is off hook. It is important that you hang-up immediately
after announcing the page to avoid recording silence.
B. Paging Port Mode
Important: The MODE SWITCH must be in the PAGING PORT position.
1. Access the phone system’s paging port.
2. Announce the page.
3. Hang-up.
If you are using the Record Page Input (see Programming section F), the SP393 will record the entire time you are
off hook on the paging port. It is important to hang-up immediately after announcing the page to avoid recording silence.
If you are NOT using the Record Page Input, the SP393’s VOX (voice activated recording) circuit will sense the pag-
ing audio and automatically begin recording the page. The SP393 will continue to record until 2 seconds of silence is
detected. The SP393 will then playback the recorded page. In this mode, the VOX sensitivity may require adjustment
(see Programming section B).
Note: For both modes, if the page exceeds the recording time, you will hear two error beeps in the handset before the page
is played. On systems that do not use the paging control output (see Programming section D), the error beeps will play
over the paging system before the page.
