The Viking SLP-1 Single Line Paging Controller will allow you to page family members or co-workers from any phone in your home or small office. The pages can be hard over the same speakers that are installed for music distribution.
The SLP-1 connects in series with a single existing phone line. The unit has a built-in 2 watt amplifier, pre-amp output, music on hold input, intercom features, and selectable loud ringing. The SLP-1 provides an input for a lighted doorbell switch, allowing a door chime to be heard over existing speakers. Page from several different phone lines by connecting multiple units.
