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.
