CSD502 Central Station Dialer/Adapter

The Alpha Communications® CSD502 Central Station Dialer / Adapter provides an interface between a nurse-call and/or emergency-call system and a POTS line for the purpose of sending alarm messages to a Central Station monitoring facility.

This provides for a supplementary notification, in addition to the normal system annunciation. The CSD502 Central Station Dialer/Adapter is external to the system's central equipment or computer, and has its own 12VDC power adapter (supplied). Connection to the central equipment/master computer is accomplished via a standard straight serial cable and a USB to serial adapter (supplied). A standard 6-position/2-wire telephone cable (supplied) is used to connect the unit to the telephone wall jack.

The CSD502 typically is used with the AlphaEntry™and/or AlphaECall™ 200 series systems, and can also be used with a variety of call systems, from other manufacturers. For connection to a USB port, use the model# CA-USBSERV10 conversion cable.
