OMNI-408/OMNI-408EU Installation and Setup Guide
4X2 Express
The 4X2 Express Reporting Format: AAAA EZ
Where:
AAAA = 3- or 4-digit account number (Program Questions 05 and 06)
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 Extended or 4X2 formats in that it can transmit a total of 225 individual reporting events.
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: AAAA 18 QXYZ GG ZZZ
Where:
AAAA =4-digit account number (Program Questions 05 and 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 below).
GG = Group number; this panel reports the group number stored in Question 29.
ZZZ = Zone, sensor, or user identifier (3 decimal digits). For zone conditions, this is the physical point
number as programmed within the individual point (01 - 32). For user-initiated actions such as
openings/closings, this is 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. It 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 (32 points and 15 users). In addition, it transmits at a much greater speed than the
conventional pulse formats, because 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 sensor (up to 32 points in this system) and to report openings/closings for many users
(up to 15 users in this system).
