Remote Site Upload/Download Downloading Initiated at a Service Terminal
Error Checking
As each block of data is received by the control panel, it is checked for accuracy. If an error is
detected, the block is retransmitted until correct, up to a maximum of four times. If the Secret Code
is not verified and four errors occur, the call is disconnected and the report that the
upload/download was not successful is called to the Central Station(s).
Central Station Acknowledge
There is an option, referred to as the ‘callback’ option, whereby the control panel will report to one
or both Central Stations that a request for uploading or downloading has been received prior to
processing the call. If the Central Station(s) does not acknowledge receipt of this request,
uploading or downloading is prohibited. If acknowledged by the Central Station(s), another
message is transmitted, informing the Central Station(s) that:
• Downloading was successful
• Uploading was successful
• Uploading/downloading was not successful
Central Station Data Protection
The primary and secondary Central Station phone numbers, communications format, account code,
test time and programmable event codes are vital Central Station information. These blocks of data
are protected from partial programming due to faulty phone connections, line noise and other
errors. This prevents the panel from being confused due to a wrong phone number, account code,
test time and most critical formatting errors.
6.2 Downloading Initiated at a Service Terminal
Before initiating the download procedure, make certain that the control panel is:
• In Normal Mode
• Central Station communications are off
• The communicator is in the standby state (red phone line active LEDs are off and Kissoff
LEDs are off)
Once the control panel accepts/answers an incoming call, the panel will:
1. Establish basic modem connection
2. Verify secret code and panel identification number
3. Verify callback vs. no callback request from the service terminal. If callback is requested,
steps 4 through 9 will occur. If no callback is requested, only steps 8 and 9 will occur
4. Identify the Service Terminal location
5. Hang-up/disconnect call
6. Call the Central Station(s) and transmit a request for upload/download message (if
programmed to do so). If this message is accepted, the control panel will proceed to the
next step
7. Return call to Service Terminal
8. After security clearance, begin downloading
9. Upon completion of download, call Central Station(s) back and report either a successful
download or failed upload/download message (if programmed to do so)
