Remote Site Upload/Download
DACT-UD PN 51899:B1 1/25/05
Two basic communication mechanisms are supported as follows:
• Download with Callback - the Service Terminal calls the control panel. The
control panel answers the call, confirms the calling party then hangs-up. The
Service Terminal then waits for a callback from the control panel. After the
control panel calls the Central Station and successfully reports that a request for
downloading has been received, the control panel calls the Service Terminal
back. Upon secret code verification, data transfers occur. When the data
transfers are completed and the Service Terminal disconnects from the control
panel, the panel calls the Central Station back to confirm either successful or
unsuccessful results
• Download with Callback Disabled - the Service Terminal calls the control panel.
No hang-up sequence occurs. Data transfers proceed.
Note: Callback enable/disable is controlled by the master user at the Service Terminal
on a per call basis.
Anytime a download with callback is initiated, the control panel will first contact the
primary Central Station or both the primary and secondary Central Stations or the first
available Central Station phone number (depending on which option has been
programmed into the control panel) to report a request for upload/download message.
Once the request is 'Kissed-off' by the Central Station(s), the control panel will then
call the appropriate Service Terminal and begin the downloading process.
Anytime a download without callback is initiated, the control panel and the Service
Terminal will communicate and transfer data without first contacting a Central Station.
When the data transfers are completed and the control panel disconnects from the
Service Terminal, the panel will call the Central Station and report the following:
• Upload/download request received
• Upload and/or download successful or
• Upload/download failed
To prevent the request for up/download message(s) from being reported to the Central
Stations(s), disable all upload/download reports back to both Central Stations.
During the downloading process, the fire protection remains active. Should a system
trouble or alarm condition occur, the control panel immediately terminates
downloading and processes the trouble or alarm locally and transmits the information
to the Central Station(s).
3.2.2 Security Features
Remote site upload and download with the control panel has been carefully designed to
include key security features to ensure proper functionality. The key features are listed
and explained below.
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 in Password
level 1 and cannot be viewed or changed by anyone other than a user with access to
level 1. 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 panel will listen for a modem connection signal. If this signal is not
received within 30 seconds, the panel will disconnect the call.
Upon successful connection (secret code verified and callback complete, if applicable),
if no communication occurs within five minutes, the panel will disconnect the call.
