Description
If you want to page family members or coworkers over your existing speakers without installing a separate intercom system, the Viking SLP-1 Single Line Paging Controller gives you whole-house or small-office paging, intercom, music distribution, and door chime functionality — all from phones you already have.
The SLP-1 connects in series with a single existing phone line, so there's no complicated rewiring involved. Its built-in 2-watt amplifier can drive up to three 8-ohm or sixteen 45-ohm speakers, and background music from an external source plays automatically through those same speakers, muting instantly whenever a page comes through. Need coverage across multiple phone lines? Simply connect additional SLP-1 units in parallel. The lighted doorbell switch input even lets you hear distinct front and back door chimes over your existing speakers when paired with a Viking C-1000B or C-2000A doorbox controller.
Whether you're running a small medical office, a retail shop, or a busy household, the SLP-1 keeps communication simple. There's no touch-tone programming to memorize — control commands are straightforward, and the bypass code feature lets you pass through auto attendants and IVR menus without the unit intercepting your key presses.
Our Expert Take: The SLP-1 is a smart, cost-effective upgrade for any home or small business already wired for background music — you're essentially adding paging, intercom, music on hold, and door chime capability to infrastructure you already own. The page trigger output (12V) is a particularly useful feature if you're running a multi-source amplifier, as it automatically enables the paging input without any manual switching. If your installation needs unique door chimes for separate entrances, pair it with the Viking C-1000B or C-2000A for that functionality right out of the box.
