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.

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.

The Viking model
SA-1H
is a 5 inch paging horn that in-
cludes a 1.5 watt power amplifier, an infrared remote control

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

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.
