Viking SA-25 Self Amplified Paging System Control

The Viking SA-25 can directly drive up to 25 self amplified speakers. Speakers can be the Viking model SA-1S self amplifier ceiling speaker, the Viking model SA-1H self amplified paging horn (pending). The SA-25 is backwards compatible with the older legacy Valcom and Bogen self amplified speakers, or any combination of the above. The Viking self amplifier speakers have the added advantage of only requiring a one pair wire loop to install all the non polarity sensitive speakers. 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 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 amplifier 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-x12 Expander / Adapter can be used if additional self amplified speakers are required.
