Extended (3x1 Ext. or 4x1 Ext.)

The Extended Reporting Format: AAA EZ or AAAA EZ
where:
AAAA = three or four digit account number (Question 15)
E = single digit event code; it is the first of the 2 programmable reporting code digits
Z = zone or user identifier; it is the second of the 2 programmable reporting code digits
Extended format is transmitted in pulse and involves a 3- or 4-digit account number
followed by a double-digit reporting code. The only purpose for using the Extended format
(sometimes known as Universal or Expanded format) is to be able to transmit more than 15
codes to the CS receiver. It does this by extending the event code from the previous round of
data resulting in a 2 digit reporting code. It can be transmitted with parity (2 rounds of
data) or without parity (4 rounds of data). There are 15 possible event codes, each of which
can have up to 15 different zone or user identifiers. Examples:
3x1 Ext. W/O PARITY 3x1 Ext. W/PARITY
123 3 (1st round)
333 1 (3rd round)
123 31 (resulting data) Burglary Zone 1
4x1 Ext. W/O PARITY 4x1 Ext. W/PARITY
1234 3 (1st round)
3333 1 (3rd round)
1234 31 (resulting data) Burglary Zone 1

Partial Extended (3x1 Part. Ext. or 4x1 Part. Ext.)

The Partial Extended Reporting Format: AAA EZ or AAAA EZ
where:
AAAA = three or four digit account number (Question 15)
E = single-digit event code; it is the first of the 2 programmable reporting code digits
Z = zone or user identifier; it is the second of the 2 programmable reporting code digits
The Partial Extended format is a combination of both the Standard and Extended formats.
It transmits in Pulse a standard message for alarm conditions and an extended message for
restores and other system conditions. To report a standard message, enter a numerical digit
(0 - 9) in the first of the 2-digit reporting code; for an extended message, enter a
hexadecimal digit (B - F) in the first of the 2-digit reporting code. The extended messages
are used whenever a zone or user identification is needed (bypasses, restores,
openings/closings, etc.). It can also transmit with and without parity. Examples:
3x1 Stand. W/O PARITY (Alarm)
123 3 (1st round)
123 3 (2nd round)
123 3 (resulting data) Burglary

3x2 or 4x2

The 3x2 or 4x2 Reporting Format: AAA EZ or AAAA EZ
where:
AAAA = three or four digit account number (Question 15)
E = single digit event code; it is the first of the 2 programmable reporting code digits
Z = zone or user identifier; it is the second of the 2 programmable reporting code digits
This format is also in Pulse and is an alternative to the Extended format; it also transmits a
2-digit reporting code. Its specific meaning is a 3- or 4-digit account number followed by a
2-digit alarm code. It can be transmitted with parity (1 round of data) or without parity (2
rounds of data).
