5.2 Transferring a Program
The first time that the control panel is downloaded (whether initiated at the jobsite or
remotely), a secret code is loaded in by a Service Terminal. Future upload or download
requests cause verification of the secret code by the control panel before processing of
data is allowed. If the secret code is not verified, the control panel will terminate the
request.
While the control panel is communicating with the Service Terminal, one of the
DACT’s red phone line active LEDs and the green Kissoff LED will turn on steady.
In order to download the panel (whether initiated at the jobsite or remotely), the
following must be true:
 The control panel must be in the Normal Mode of operation. Downloading is
not possible if the panel is in any other mode
 There cannot be any active communications ongoing with a Central Station
receiver
 All active events must be successfully 'kissed-off' by the Central Station(s).
The communicator must be in a standby state with no new information waiting
to be transmitted to a Central Station
5.2.1 Security Features
Upload and download with the control panel have been carefully designed to include
key security features to ensure proper functionality. Any time a transfer is initiated, the
control panel and the Service Terminal will communicate and transfer data before
contacting a Central Station. When the data transfers are completed and the control
panel disconnects from the Service Terminal, the control panel will call the Central
Station and report one of the following conditions:
• Upload/Download request received
• Upload and/or Download request successful
• Upload/Download failed
The key features are listed and explained in the following sections.
Secret Code Verification
A secret code is stored in the control panel by a Service Terminal to prevent
unauthorized access. The secret code is created at the Service Terminal by the master
user and cannot be viewed or changed by anyone other than a master user. Viewing of
the secret code is prohibited at the control panel. Prior to allowing an upload or
download of data, the control panel will verify the secret code transmitted by the
Service Terminal.
Time-out at Control Panel
Upon answering an incoming call on either the primary or secondary Central Station
phone line, the control panel will listen for a modem connection signal. If this signal is
not received within 50 seconds, the control panel will disconnect the call. Upon
successful connection (secret code verified), if no communication occurs within 30
minutes, the panel will disconnect the call. Upon time-out, transfer activity will be
reported to the Central Station (if enabled) and the connection will be terminated.
