System Communication
This section provides an explanation of formats this system accommodates for reporting alarms and other
system conditions to the central station. The process of a successful transmission consists of both the
method of communication between the control panel and the central station receiver, and the actual way the
information is sent and displayed at the central station.
Communication Overview
When the panel calls the central station receiver, it waits to hear a “handshake” frequency from the receiver
to confirm that the receiver is on-line and ready to receive its message. Once the panel hears the handshake
it is programmed to listen for, it sends its message. The panel then waits for a “kissoff” frequency from the
receiver acknowledging that the message was received and understood.
3
If the handshake frequency is not given or is not understood by the panel, the panel will not send its
message. Once the handshake frequency is received and understood by the panel, the panel will send its
message. If there is an error in the transmission (the receiver does not receive a “valid” message), the kissoff
frequency will not be given by the central station receiver.
The panel will make eight attempts to the primary telephone number and eight attempts to the secondary
telephone number (if programmed) to get a valid message through. If the panel is not successful after its
numerous attempts, the keypad will display “FC.” If the secondary number is a pager, “FC” displays after
the first 8 attempts to the primary number.
The following chart defines the three sets of (handshake/kissoff) frequencies that the panel supports, and the
different formats that can be sent for each.

Report Code Formats
3+1 and 4+1 Standard Formats
Comprise a 3- (or 4-) digit subscriber number and a single digit report
code (e.g. alarm, trouble, restore, open, close, etc).
3+1 and 4+1 Expanded Formats
Comprise a 3- (or 4-) digit subscriber number, and a 2-digit report code.
The first digit is displayed on the first line, followed by a second line
where the first digit is repeated 3 (or 4) times and followed by the
second digit. This is the “expanded” digit.
4+2 Format
Comprises a 4-digit subscriber number and 2-digit report code.
ADEMCO Contact ID®
Comprises a 4-digit subscriber number, 1-digit event qualifier
Reporting Format
(“new” or “restore”), 3-digit event code, and 3-digit zone number, user
number, or system status number (see the following page).
The following table shows the message formats for 3+1, 4+1 and 4+2 reports, where:
SSS or SSSS = Subscriber ID
C = Close Code (1st Digit)
A = Alarm Code (1st digit)
U = User Number (in hex)
Z = Typically Zone Number* (2nd digit)
G g = Test Code (1st & 2nd digits)
T t = Trouble Code (1st & 2nd digits)
R = Alarm Restore Code
B b = Bypass Code (1st & 2nd digits)
R Tt = Trouble Restore Code (1st & 2nd digits)
E A C = AC Loss Code (1st & 2nd digits)
R Bb = Bypass Restore Code (1st & 2nd digits)
L L B = Low Battery Code (1st & 2nd digits)
R AAC = AC Restore Code (1st & 2nd digits)
O = Open Code (1st Digit)
R LLB = Battery Restore Code (1st & 2nd digits)
