A Successful Transmission
When a control 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.
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 is not given by the central station receiver.
The panel will make a number of attempts to the primary telephone number and a number of
attempts to the secondary telephone number (if programmed) to get a valid message through.
The number of attempts that are made to each number is determined by the programming of
field 3 21. If the panel is not successful after its numerous attempts, the keypad will
display COMM FAILURE.
Reporting Formats
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.
