DESIGN
General
The Valcom V-1101A One-Zone One-way Page Adapter is designed to provide access to paging from a standard PABX loop trunk port, an electronic key system or 1A2 key system C. O. line button, or a 1A2 key system intercom number. In some cases, access is also possible from a PABX or electronic key system page port.
REMEMBER: All Valcom paging systems are made
up of three basic components: a page control unit, speakers, and a power supply.
When one-way amplified speaker assemblies are specified in this manual, consult your Valcom catalog for the styles available. Once the style and quantity of speakers is determined, select the appropriate power supply after referring to the Valcom One-way Paging manual or the Valcom catalog.
In addition to the parts listed in each of the following sections, you will need a 66B type punch down block and a 25-pair cable with a female amphenol connector. These may be purchased from Valcom as a unit with the cable and block already connected and installed on a mounting frame (part # VM-101).
