Panel Communication with Central Station
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 (on an alpha keypad) or FC (on a 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.
