5.3.4 CSD Method
ATTENTION:
It is necessary to set monitoring station phone number on alarm system for
CSD
method. In such case you can
use any number (one digit is enough).
By this method the communicator receives
Ademco Contact ID®
protocol data sent from alarm system, converts it to CSD protocol
data message and transmits it to monitoring station via CSD connection.
Set the following ET082 parameters using
ELDES Configuration Tool
software:
1. Switch to
Advanced
mode by enabling
Backup Enabled
parameter.
2. Select
CSD
method as
Primary
connection.
3. Set
Backup 1
and
Backup 2
connections if required.
4.. Set CSD monitoring station phone number.
For more details, please, refer to
ELDES Configuration Tool
software’s HELP section.
If PSTN connection is used, the communicator also monitors the voltage (dial tone monitoring optional) on the PSTN and in case
the PSTN is unavailable, disconnected or cut off (voltage drops below 4V), ET082:
• switches to
CSD
method,
• notifies monitoring station about PSTN failure,
• continues transmitting data to monitoring station via CSD connection until the PSTN is restored.
NOTE:
In case of
CSD
method failure the communicator switches to
Backup 1
and
Backup 2
connections (if set) respectively and
attempts to continue transmitting data to monitoring station until the previous connection (-s) is restored.
