There are 15 possible event codes, each of which can have up to 15 different zone identifiers.
It is different from the extended format in the way it transmits. This is illustrated in the
examples below:
3x2 w/o PARITY
123 31 (1st round)
123 31 (2nd round)
123 31 (resulting data) Burglary Zone 1
4x2 w/o PARITY
1234 31 (1st round)
1234 31 (2nd round)
1234 31 (resulting data) Burglary Zone 1
FBII Superfast (4x3x1)
The FBII Superfast Reporting Format: AAAA AZZ S
where:
AAAA = four digit account number (Program Question 15)
A = alarm type; it is the first of the 2 programmable reporting code digits
ZZ = zone or user identifier; it is the second of the 2 programmable reporting code digits
S = signal type; it is the first of the 2 programmable reporting code digits
This format is commonly known as 4x3x1. A total of 9 digits (including the parity digit) are
sent in DTMF. It enables reporting of up to 256 (00 - FF) unique zone or user identifiers
instead of the 15 possible identifiers of most other pulse formats. In addition, it transmits at
a much greater speed than the conventional pulse formats, since it uses DTMF (touch tones)
instead of pulses to transmit the data and it always sends a parity digit.
For alarms, openings, and closings, the alarm type digit will be the same as the signal type.
This will indicate the type of activity or condition that has occurred. However, on bypasses,
restores, and troubles, the alarm type will not be the same as the signal type. Instead, the
Signal Type will change indicating the current condition of the zone. NOTE: This is a
unique feature of this format which allows more intelligent reporting of the activity
occurring in the system. For instance, the following unique messages can be transmitted:
1234 1 01 1
1234 1 01 E
1234 1 01 F
ADEMCO 4x1 Express
The 4x1 Express Reporting Format: AAAA E 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
This format transmits in DTMF a total of 6 digits (including the parity digit). It is similar to
the Standard format in that it can only transmit a total of 15 reporting codes. However, its
advantage is speed because it transmits touch tones instead of pulses and it always sends a
parity digit. Examples:
123 3 6 (1st round)
123 3 (resulting data) Burglary
ADEMCO 4x2 Express
The 4x2 Express Reporting Format: 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 transmits in DTMF a total of 7 digits (including the parity digit). This format is
similar to the 4x1 Extended or 4x2 formats in that the output sends a 4-digit account and 2-
digit event code. However, its advantage is speed because it transmits touch tones instead of
pulses and it always sends a parity digit. Examples:
3x2 w/PARITY
123 31 5 (1st round)
123 31 (resulting data) Burglary Zone 1
4x2 w/PARITY
1234 31 1 (1st round)
1234 31 (resulting data) Burglary Zone 1
Fire Zone 001
Restore Fire Zone 001
Trouble Fire Zone 001
