Operation - DIGITIZE DDI-11E Installation & User Manual

5 Operation

Chapter 5, Operation will explain how the DDI-11E operates, collecting and
processing alarms and transmitting them to the System 3505.
The DDI-11E Dual Line External Dialer Receiver Module processes any Alarm,
Trouble and Secure conditions it receives and converts the coded information into
the proper format for processing by the SYSTEM 3505. The operator sets up
Configuration Tables to translate Alarm codes into zones and set the English
Equivalents. After the Configuration Tables are set up, the operator enters specific
customer account numbers for each Configuration table. (Refer to Section 4.4
Configuration Tables for more details.)
When the SYSTEM 3505 receives an alarm, it takes the code it receives, looks up
the customer number and determines which configuration table to use to convert the
alarm. If the SYSTEM 3505 receives an alarm for a customer number that is not
programmed, a message will print to alert the operator of the problem.
For example: The SYSTEM 3505 receives the information Customer 123 message
E. If it does not recognize Customer 123, the following message will print:
NO CUST # 123 PRG'D
13 Feb 13 19-30-01
RAW 1 DD # 3 123-E
`
The SYSTEM 3505 prints the actual code message it receives as an alarm. The
third line of the message is the actual data transmitted to the DDI-11E. 'RAW'
indicates the information to follow is the actual code received. The '1' indicates the
protocol used to decode the message. 'DD # 3' indicates the dialer number. '123-E'
indicates that Customer 123 has a code E. Anytime the SYSTEM 3505 does not
recognize the Customer number or message code it will process the raw data as an
alarm.
The DDI-11E converts any single digit alarm message to a two digit message.
When alarm code 123-X is sent to the DDI-11E, the SYSTEM 3505 processes a
code 123-XX (where xx is zone 01 - zone 99).
