Section 14. 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.
Report Code Formats
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 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 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 will display “Communication Failure” (Alpha keypad) or
“FC” (Fixed-word keypad).
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.
FORMAT HANDSHAKE TRANSMITS DATA KISSOFF TRANSMIT TIME
Low Speed 1400Hz 1900Hz (10PPS) 1400Hz Under 15 secs.
3+1 (Standard report)
4+1
4+2
Sescoa/Rad 2300Hz 1800Hz (20PPS) 2300Hz Under 10 secs.
3+1 (Standard report)
4+1
4+2
Express 1400–2300Hz DTMF (10 cps) 1400Hz Under 3 secs.
4+2
Contact ID 1400–2300Hz DTMF (10 cps) 1400Hz Under 3 secs.
The following describes each format in greater detail.
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 two-digit re -
port code. The first digit is displayed on the first line, followed by
a second line where the first digit is re peated 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).
