Report Code Formats - ADEMCO Vista-20HW Installation Instructions Manual

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 "Comm 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.
