The communicator can be used for:
Transmitting alarm signals to alarm receiving equipment at a central
monitoring station using Scancom Fast Format, Scancom SIA (Security
Industry Association) or Contact ID (set with Command 103).
Connecting to a PC based at a remote engineering centre. Using
Scantronic Downloader software, the remote PC can upload and download
system parameters (including the event log and diagnostics), set and unset
the alarm system, and carry out other special functions.
Programming commands 101 to 159 are used to configure communication.
Telephone Line
Ideally, the internal communicator should be connected to an ex-directory line
used exclusively for alarm communications.
If an exclusive line is not available and other apparatus is connected to the
line (for example, an answer machine), the internal communicator provides a
series connection with line divert for the other apparatus. When triggered, the
communicator seizes the line and disconnects the other apparatus. When the
communicator shuts down, it reconnects the other apparatus.
Three-way Calling
The control unit provides a three-way calling facility to make sure the internal
communicator can always use a shared telephone line.
To use this facility, the local exchange must provide the three-way calling
service on the customer's line.
Line Monitoring
The control unit provides a line monitoring function to check that the
telephone line is connected and working, and indicate a line failure if it is not.
While enabled, this function continually checks the line voltage to ensure that
the line is connected. If it detects a failure, the system gives the Line Fault
Response selected with Command 106.
Test Calls
The control unit can be programmed to make test report calls to an ARC.
"Static" test calls can be programmed to occur at set times or intervals.
"Dynamic" test calls occur 24 hours after the last call made by the unit. See
"4. Programming" for details on how to program these functions with
Commands 105 and 108.
