Expand Existing Paging Systems and

Add Remote Control to the New Speakers

Features

The Viking SA-X12 expander / adapter is an

economical way to expand an existing paging

system, while adding remote control to the new

speakers. The SA-X12 can be connected to any

existing paging audio source including 600 ohm

line level, 4, 8, or 16 ohm speaker level, or even

25 volt and 70 volt paging systems. It can also be

connected directly to the 2-wire protocol (40VDC

+ Audio) of another SA-X12 or the Viking SA-25

paging controller to add even more self amplified

speakers.

The SA-X12 takes audio from any paging or

background music source, and combines it with 40

volts DC to run Viking self amplified speakers. The

added Viking SA Series speakers will have the

features of the existing paging system, plus have

the added feature of being remote controllable.

The SA-X12 can directly drive up to 12 Viking self

amplified speakers which include the model SA-1S

self amplifier ceiling speaker, and the SA-1H self

amplified paging horn. Viking self amplified

speakers have these advantages: 1) Audio and

power are on the same pair (less copper). 2)

• Powers up to 12 Viking self amplified

speakers

• Viking SA Series speakers are remote

controllable

• Expand existing paging systems

• Adapts to any paging system

• 600 ohm line level paging systems

• 4, 8, or 16 ohm paging systems

• 25 volt and 70 volt paging systems

• Expand a Viking SA-25 paging system

Power is 40VDC for lower current and smaller

gauge wire (less copper then older 4-wire 24 volt

systems). 3) Non-Polarity sensitive for easier

wiring. 4) Each speaker is infrared remote

controllable so there is no need to install volume

controls on the walls, or climb up ladders to adjust

the volume.

The SA-IR Infrared Remote and SA Series

speakers are available separately.

Operation

The SA-X12 takes audio from any paging or background music source, and combines it with 40VDC to run Viking

self amplified speakers. The added Viking SA Series speakers will have the features of the existing paging system,

plus have the added feature of being remote controllable.

The SA-IR remote control functions essentially like a TV remote control. Point the remote at the Viking SA Series

speaker you wish to control and push the buttons. The speaker volume can be stepped up or down, or the speaker

can be totally muted. When the speaker is muted, pressing the mute button again, or the volume up or down buttons,

will release the mute. A short “beep” will be heard through the speaker when the mute is activated. A long “beep” will

be heard through the speaker when the “MUTE” button is pressed again releasing the mute.

If the SA-X12 is used to expand more speakers to a Viking SA-25 paging control unit, the added speakers will be

compatible with the SA-25’s “Smart Mode” feature. In this special “Smart Mode” the SA-IR Remote Control “MUTE”

button functions as a “mute background music button”. All paging and loud ringing sound will be amplifier through the

speaker, but the speaker then mutes the background music. This feature is useful for speakers which are mounted in

a meeting room in which pages need to be heard, but background music would be obstructive. This feature enables

an office with background music to become a quite meeting room with the bush of a button.

The Viking model SA-1S is an 8 inch paging speaker that has a built in

1.5 watt power amplifier, an infrared remote control detector, and an inte-

grated digital volume control, all built into an attractive off-white grill for

flush mounting in office ceilings. The SA-1S self amplified paging speaker

uses a proprietary two wire protocol in which both 40 volts DC power and

audio are combined on the same pair of wires. It is designed for direct con-

nection to the Viking model SA-25 Self Amplified Paging Control unit, or

use the Viking model SA-X12 expander/adapter to connect it to virtually

any existing paging system.

The SA-1S speaker includes an infrared receiver to accept volume control

signals from a Viking model SA-IR remote control. Aim the infrared trans-

mitter at the speaker and press the buttons. The up/down buttons allow users to set the appropriate volume level for

each speaker. The speaker provides an audible “beep” feedback tone to let the user gauge the volume level even when

there’s no background music (or page) playing at the time.

Compatible Products

The SA-25 can directly drive up to 25 self amplified

speakers. Speakers can be Viking’s 2 wire self amplified

ceiling speaker model SA-1S, the SA-1H self amplified

paging horn, the older 4 wire legacy Valcom and Bogen self

amplified speakers, or any combination of the above. Viking

self amplified speakers have these advantages: 1) Audio and

power are on the same pair (less copper). 2) Power is 40VDC

for lower current and smaller gauge wire (less copper). 3)

Non-Polarity sensitive for easier wiring. 4) Each speaker is in-

frared remote controllable so there is no need to manage and

wire “background music zones”, install volume controls on the

walls, or climb up ladders to adjust the volume. The provided SA-

IR Infrared Remote controls volume, mute, and enable/disable

background music at each speaker as required.

The SA-25 provides paging, loud ringing, and background music when connected to electronic or 1A2 Key systems,

PABX’s, No-KSU phones, multi-line phones, as well as IP phone systems (that have an analog FXS or FXO port). The

SA-25 paging control unit can interface with a paging port or a ringing analog FXS, CO/Centrex line, PABX/KSU station

port or an FXO, unused telephone line input (trunk port).

The SA-25 will generate loud ringing from a ringing analog line or from a dry contact closure. Either a loud electronic

warble sound or one of three other soft chime sounds may be selected. An external “night transfer” switch (such as

Viking model NS-1) can be added to turn loud ringing on or off in night bell applications. If a music source is connected

to the SA-25, background music can be enabled or disabled at any Viking self amplified speaker using the provided SA-

IR infrared remote control. Background music is inhibited during paging. The SA-25 is easy to install and comes complete

with a power supply.

Self Amplified Paging Control Unit with IR Remote

For more information, see DOD 520

The Viking model SA-1H is a 5 inch paging horn that in-

cludes a 1.5 watt power amplifier, an infrared remote control

detector, and an integrated digital volume control. The SA-

1H self amplified paging horn uses a proprietary two wire

protocol in which both 40 volts DC power and audio are com-

bined on the same pair of wires. It is designed for direct con-

nection to the Viking model SA-25 Self Amplified Paging

Control unit, or use the Viking model SA-X12

expander/adapter to connect it to virtually any existing pag-

ing system.

The SA-1H includes an infrared receiver to accept volume

control signals from a Viking Model SA-IR remote control.

Aim the infrared transmitter at the receiver and press the

buttons. The up/down buttons allow users to set the appro-

priate volume level for each speaker. The speaker provides an audible “beep” feedback tone to let the user gauge the

volume level even when there’s no background music (or page) playing at the time.
