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).
