The SS-1002 and SS-2002 Intercom Speaker Stations may be used with a headset, or with the built-in speaker and the panel microphone or an optional gooseneck microphone. As an alternative to a headset, a telephone-style handset may also be used. The SS-1002 is a single-channel station; the SS-2002 provides switch selectable access to either of two intercom channels. Both the SS-1002 and SS-2002 come in three versions to suit a variety of applications. The “S” box is a portable version. It has a carrying handle and dual “loop-through” intercom connectors which permit stations to be quickly interconnected using pre¬fabricated cables. The “P” box is a stationary version. It also has dual “loop-through” connectors for quick interconnection, but the case is designed for desktop or console-mount applications. The “U” box is designed for permanent, in-the-wall mounting. It uses push type wire terminals for connection to the intercom system
