Description
Managing paging, ringing, and background music across dozens of speakers shouldn't require a complicated setup — the Viking SA-25 brings it all together in one self-amplified system controller that drives up to 25 speakers with minimal wiring and no guesswork.
The SA-25 connects directly to electronic or 1A2 key systems, PABXs, no-KSU phones, multi-line phones, and IP phone systems with an analog FXS or FXO port, making it a flexible fit for virtually any existing phone infrastructure. It delivers amplified paging, loud ringing, night bell functionality, and background music from a single unit. When a page or call comes in, background music automatically mutes so your announcements always cut through clearly. Viking's self-amplified ceiling speakers and paging horns connect using just a single pair of non-polarity-sensitive wire — a real time-saver during installation.
Need more than 25 speakers? The SA-X12 Expander/Adapter adds capacity 12 speakers at a time, and the 600-ohm output lets you cascade additional SA-25 units for larger deployments. The included SA-IR Infrared Remote gives you hands-on control of volume, mute, and background music enable/disable at each speaker location as needed.
Our Expert Take: The SA-25 is a strong choice for small to mid-size offices, warehouses, or facilities that already have an analog or hybrid phone system and want a clean paging and music solution without rewiring. The backwards compatibility with legacy Valcom and Bogen self-amplified speakers is a genuine money-saver for anyone upgrading an older system — you may not need to replace a single speaker. If your space is growing, plan ahead and grab the SA-X12 expander at the same time to keep future expansion simple.
