DEES DSI-375, User Manual

Page: 6 / 48

The DSI is capable of performing many different functions. These
functions are described as configurations in this User Guide.
Configurations can be linked together so that the DSI can perform more
than one task.
Each configuration is described briefly here. More detailed explanations
are located on pages 18-29.
Configuration 0
Clear Memory or Factory Default Setting
Clears all previous programming and returns DSI to its factory default
setting. See page 18.
Configuration 1
Monitoring Off-Hook Busy
Used to monitor an "off-hook" state. When detected, the DSI will close a
set of contacts which can be used to light a lamp. Configuration 1 can
also be used in conjunction with the "make busy" feature of the Meridian
Business Set so that a set of contacts will close when this feature is
activated. See page 19.
Configuration 2
Second Call or Intercom Alert Tone Amplification
When there is a second incoming call, an intercom call or a ring again
call on the MBS or associated add-on module, the DSI rings once. See
page 20.
Configuration 3
Simultaneous Ringing
When the MBS rings, the DSI rings and activates any connected
auxiliary equipment, e.g., a ringer or a lamp. See page 21.
Configuration 4
Set Idle On-Hook
When an LCD on selected lines flashes, the DSI rings and can activate
any connected auxiliary equipment, e.g., a ringer or a lamp. See page 22.
Configuration 5
Set Busy Off-Hook
When an LCD on selected lines flashes while the MBS is off-hook, the
DSI rings and can activate any connected auxiliary equipment, e.g., a
ringer or a lamp. See page 23.
