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

ringing line to screw terminals 9 & 10 for this feature.

B. Loud Ringing

1. Ringing Line

Some phone systems provide a “common audible” dry contact closure whenever a call is coming in. Wire the

contact closure across screw terminals 11 & 12 for this feature.

DIP Switch 5 ON: This input provides a door chime through the speakers when a contact closure is detected.

DIP Switch 5 OFF: This input provides loud ringing through the speakers when a contact closure is detected.

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

Connect an external switch across screw terminals 11 & 12, when the switch is closed, the loud ringing sound

(or door chime if DIP switch 5 is ON) will sound once and loud ringing will be disabled. When the switch is

opened, a double beep will be heard (if DIP switch 5 is OFF) through the speakers to indicate loud ringing en-

abled.

3. Night Transfer

The PA-15 can produce one of 4 selectable loud ringing sounds. Use DIP switches 1 and 2 to choose between

Electronic Warble, Double Gong, Quadruple Chime, or Door Chime sounds. Select the Electronic Warble tone

(traditional loud ringing) for noisy areas. The softer chimes work well in quieter environments. The loud ringing

volume can be adjusted with the trim POT in the middle (R13).

4. Loud Ringing Sounds

The PA-15 can be interfaced to an analog extension or FXS port by setting the FXO/FXS switch to FXS and

connecting the wires to screw terminals 5 & 6. In this mode a ring signal triggers the PA-15 to grab the line,

send a tone over the line, and then (if DIP switch 8 is on) over the speakers, after which you may speak. The

PA-15 will end the page when either a busy signal (if default timer is not 16 seconds) or CPC is detected, or

the silence timer (DIP switches 3 & 4) or default timer (DIP switches 9 & 10) runs out. Paging audio volume

can be adjusted with the trim POT on the left (R6).

C. Paging

1. Analog Extension or FXS port

The PA-15 can be interfaced to a trunk input, FXO port, or analog phone by setting the FXO/FXS switch to

FXO and connecting the wires to screw terminals 5 & 6. In this mode an off hook condition triggers the PA-15

to pause 1 second, send a tone over the line, and then (if DIP switch 8 is on) over the speakers, after which

you may speak. The PA-15 will end the page with a 2 second CPC when either a busy signal (if default timer

is not 16 seconds) or hang up is detected, or the silence timer (DIP switches 3 & 4) or default timer (DIP

switches 9 & 10) runs out.

2. Trunk Input, FXO port, or Analog Phone

The PA-15 can be interfaced to a phone system paging port by setting the FXO/FXS switch to FXS, turning

DIP switch 6 ON, and connecting the wires to screw terminals 5 & 6.

With Page Contacts: If the phone system supplies a page contact, wire it to screw terminals 7 & 8. When the

contact closes the PA-15 will send a tone to the port and then (if DIP switch 8 is ON) over the speakers, after

which you may speak. The PA-15 will end the page when the contacts open.

Without Page Contacts: If the page contacts are not used, then the PA-15 relies on a Voice Activation Switch

(VOX) feature that will switch to paging when voice audio is detected. In this mode the PA-15 does not have

the opportunity to supply a page alert tone. The VOX sensitivity can be adjusted by turning DIP switch 7 ON

to reduce the sensitivity if noise on the wires creates false pages. The PA-15 will end the page when the silence

timer (DIP switches 3 & 4) or default timer (DIP switches 9 & 10) runs out.

3. Paging Port

This audio output is provided so that additional paging amplifiers can be added if additional paging power is

needed. This is a 600 ohm line level output that can be connected into any single ended amplifier input (such as

a second PA-15 or a PA-60).
