Section 8. Central Station Reporting Formats
8-5
ADEMCO 4x2 Express
The 4x2 Express Reporting Format:
AAAA 27 EZ,
where:
AAAA
= Three- or four-digit account number (Submode 1, Questions 05–06)
27
= Uniquely identifies this format to the receiver and to an automation system but is not
displayed or printed
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 and 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:
1234 31 1 (1st round)
1234 31 (resulting data) Burglary Zone 1
ADEMCO Point ID
The Point ID Reporting Format:
AAA 18 QXYZ ZZZ,
where:
AAAA
= Four-digit account number (Submode 1, Questions 05–06)
18
= Uniquely identifies this format to the receiver and to an automation system but is not
displayed or printed
Q
= Event qualifier, which gives specific event information
1 = New Event or Opening
3 = New Restore or Closing
XYZ
= Event Code: The event code is a 3-digit code (3 decimal digits). For zone alarms and some
conditions, this can be specified; other conditions are dedicated. See the tables that follow.
ZZZ
= Zone, sensor or user identifier (3 decimal digits). For user initiated actions such as
openings/closings, this will be the actual user number (01–15).
This format is also known as ADEMCO Contact ID. A total of 16 digits (including the parity digit) are
sent in DTMF. This format enables reporting of 999 (001–999) unique zone or user identifiers instead of
the 15 possible identifiers of most other pulse formats. This feature allows the full reporting capability
of this system (12 zones and 15 users). 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. Its main advantage over all the other formats is its large number of event
codes (see tables below) with the ability to pinpoint an event (alarm, trouble, bypass, restore, etc.) to a
specific zone and to report openings/closings for many users.
Some open/close events generate fixed PID codes and user numbers that cannot be changed or
suppressed. These open/close events are listed below:
