Getting On-Line with a Control Panel
At the protected premises, the control panel must be
connected to the existing telephone line (refer to
SECTION 3: Installing the Control). No programming
of the panel is required before downloading to an initial
installation unless you are performing an unattended
download.
When establishing a connection between the computer
and the control panel, the following occurs:
Stage What Happens
1 The computer calls up the control panel.
(The phone number for each customer must
be entered into the customer’s account file
on the computer.)
2 The control panel answers the phone call at
the pre-programmed ring count and executes
a handshake with the computer.
3 The computer sends a request for callback to
the control, unless callback is not required.
4 The panel acknowledges the request and
hangs up. During the next few seconds, the
control processes the request, making sure
certain encrypted information received from
the computer matches its own memory.
5 Upon a successful match, the control panel
seizes the phone line and calls the computer
back, unless callback is not required. (The
phone number to which the computer’s
modem is connected must be programmed
into the control field ✳35.)
6 The computer answers, usually by the
second ring, and executes a handshake with
the panel.
7 The panel then sends other default
information to the computer. If this
information matches the computer’s
information, a successful link is established.
The system is now “on-line” with the
computer.
Alarms and Trouble responses and reports are
disabled during actual uploading or
downloading sessions.
To download a control without programming any
information, perform the following steps:
Step Action
1 Enter the Installer Code + [#] + [5]. The
panel temporarily enables a ring count of 5
and sets the Download Callback option to “1”
(callback not required).
2 From the computer, call the panel using the
downloader software set to “First
Communication” Mode.
The downloader establishes a session with no
callback. The panel information can then be
downloaded.
On-Line Control Functions
The following functions can be performed while on-line
with a control panel (see field *37):
• Arm the system in the AWAY Mode; disarm the
system
• Bypass a zone
• Force the system to accept a new program
download
• Shut down communication (dialer) functions (for
nonpayment of monitoring fees in an owned
system)
• Shut down all security system functions (for
nonpayment for a leased system)
• Inhibit local keypad programming (prevents
takeover of your accounts)
• Leave a message for customer
NOTE: Messages sent to the control panel from the
downloader will be viewable at ALL partitions.
• Command the system to upload a copy of its
resident program to the office
• Read: arming status, AC power status, list of
faulted zones, list of bypassed zones, 100 event log,
list of zones currently in alarm, list of zones
currently in trouble, and ECP equipment list
