System Communication and Operation
Panel Communication with Central Station
This system accommodates several formats 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.
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.
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 sends its
message. If there is an error in the transmission (the receiver does not receive a “valid” message), the kissoff
frequency is not given by the Central Station receiver.
The panel makes a total of 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 displays COMM. FAILURE (on alpha keypads) or FC (on fixed-
word keypads).
Report Code Formats
The following chart indicates the types of (handshake/kissoff) frequencies that the panel supports and the
different formats that can be sent with each.
FORMAT HANDSHAKE TRANSMITS DATA KISSOFF TRANSMIT TIME
Low Speed 1400 Hz 1900Hz (10PPS) 1400 Hz Under 15 secs
3+1, 4+1, 4+2

The following table describes each format in greater detail.
FORMAT TYPE DESCRIPTION
3+1 and 4+1
Standard Formats
Comprises 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
Comprises a 3- (or 4-) digit subscriber number and a two-digit report code.
The first digit is displayed on the first line. On the second line, it is repeated
3 (or 4) times and is 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
Reporting Format
Comprises a 4- or 10-digit subscriber number (depending on format
selected), 1-digit event qualifier (new or restore), 3-digit event code, and
3-digit zone number, user number, or system status number (see the
following page).
