This audio input allows background music from an external source to plug into the SA-25. While any other input is active, back-

ground music is turned off, so music will only be heard through the speakers when all other inputs are idle. A 3.5mm (1/8”) audio

cable is provided, and the music level can be set using the trim POT just behind the Background Music input jack.

A. Background Music In

This input provides loud ringing through the speakers whenever ringing voltage is detected. Connect an analog ringing line to

screw terminals 16 & 17 for this feature.

B. Loud Ringing

1. Line In

This input provides loud ringing through the speakers whenever a contact closure is detected. Some phone systems provide a

“common audible” dry contact closure whenever a call is coming in. Wire the contact closure across screw terminals 18 & 19 to

provide loud ringing from the SA-25.

2. Contact Closure

This input can be used to disable loud ringing. For example, if loud ringing is only necessary during off business hours, an exter-

nal switch can be added to disable loud ringing during the day, and transfer it back on at night. Wire an external switch (such

as Viking model NS-1) across screw terminals 19 & 20. When the switch is closed, loud ringing will be disabled.

3. Night Transfer

The SA-25 can produce one of 4 selectable loud ringing sounds. Use DIP Switches 5 and 6 to choose between Electronic

Warble, Double Gong, Quadruple Chime, or Door Chime sounds for loud ringing. Select the Electronic Warble tone (traditional

loud ringing) for noisy areas. The softer chime tones work well in less noisy environments.

4. Loud Ringing Sounds

C. Paging In

1. Ringing Analog Station (FXS), C.O. Line, or Centrex Line

If paging from a ringing analog station (FXS), C.O. line, or Centrex line, DIP Switch 1 must be OFF, and the Slide Switch set to

RING TRIP. Dial the station or phone line number, and the SA-25 will answer the line after the first ring is detected. Wait for the

Pre-Page Alert Tone to pass (if enabled), and then speak. The SA-25 will drop the line once it detects silence, busy signal,

reorder signal, or a CPC break. If none of those are detected, the SA-25 will drop the line at a default time out of 60 seconds.

This audio input allows paging from a ringing analog station port (FXS), CO line or Centrex line, a phone system’s unused trunk/line

input (FXO) or dedicated telephone, or a paging port. Wire the appropriate page source to screw terminals 12 & 13 as shown in the

Installation section, and follow the operation for your type of paging as described below.
