LXL-1010 and Dialer 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).

DESCRIPTION
Comprises a 3- (or 4-) digit subscriber number and a single-digit report
code (e.g., Alarm, Trouble, Restore, Open, Close, etc).
Comprises a 3- (or 4-) digit subscriber number and a two-digit report code.
The first digit is displayed on the first line. On the second line, it is repeated
3 (or 4) times and is followed by the second digit. This is the "expanded"
digit.
Comprises a 4-digit subscriber number and 2-digit report code.
Comprises a 4- or 10-digit subscriber number (depending on format
selected), 1-digit event qualifier ("new" or "restore"), 3-digit event code, and
3-digit zone number, user number, or system status number (see the
following page).
