Variations of these formats
may be programmed at
the subscriber's premises
and may use a different
handshake signal from
those listed; similarly,
some formats listed for
double-round verification
may be programmed for
parity checking. See

4x1 Standard Format
The 4x1 Reporting Format is among
the most basic and easy to
understand, but sacrifices details
which are often advantageous for the
subscriber, the Central Station, and
the responding authorities.
A slight variation in the 3x1 Standard Format allows for a
4-digit Account Number, and is therefore known as the
4x1 Standard Format . It, too, is a pulsed format, and for
all intents and purposes, is identical to the 3x1 Standard
Format.
1 2 3 4 5
With the hexadecimal numbering system found in many
communication formats, it's possible to send hexadecimal
characters in
4x1 Standard, depending on the
communicator. If "hex" is used, each digit may have up to
15 possibilities:
0 - 9 = 10 possibilities
+
B - F = 5 possibilities
NOTE 1: While 15 possibilities per digit permit Account
Numbers to be expressed in hexadecimal, it is the
last digit, the
Event Code, which profits most from
the use of "hex." As such, the reporting of 15 distinct
events can be accomplished via this format, and
often follows the arrangement shown in this table:
