General Remote Site Upload/Download
• Contact with callback disabled - The Service Terminal calls the communicator. No hang-up
sequence occurs. Data transfers proceed.
Note that Callback enable/disable is controlled by the master user at the Service Terminal on a per
call basis.
With program address location 64 set to '1' in Program Mode, anytime a contact with callback is
initiated, the communicator will first either contact the primary Central Station or contact both the
primary and secondary Central Stations or contact the first available Central Station phone number
to report a 'request for upload/download' message (depending upon the program entry in address
location 137). Once the request is 'kissed-off' by the Central Station(s), the communicator will then
call the appropriate Service Terminal and begin the downloading process.
With program address location 64 set to '1' in Program Mode, anytime a contact with callback dis-
abled is initiated, the communicator and the Service Terminal will communicate and transfer data
without first contacting a Central Station. When the data transfers are completed and the communi-
cator disconnects from the Service Terminal, the communicator will call the Central Station and
report one of the following:
• Upload/download request received
• Upload and/or download successful
• Upload/download failed
To prevent the 'request for upload/download' message(s) from being reported to the Central Sta-
tion(s), make certain to set address 64 to ‘0’ or ‘3’ or disable all upload/download reports back to
both Central Stations. Refer to Table 3.2 on page 38 through Table 3.4, “Ademco Contact ID For-
mat - Secondary,” on page 42 for additional information.
Unlike most competitive products, during the downloading process, the input monitoring and
411UDAC supervision remain active. Should an input activation or system trouble occur, the com-
municator immediately terminates downloading, processes the trouble or alarm locally and trans-
mits the information to the Central Station(s).
5.1.1 Security Features
Remote site upload and download with the 411UDAC have 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 communicator by a Service Terminal to prevent unauthorized access.
The secret code is created at the Service Terminal by a Master user and cannot be viewed or
changed by anyone other than a Master user. Viewing of the secret code is prohibited at the com-
municator. Prior to allowing an upload or download of data, the communicator will verify the
secret code transmitted by the Service Terminal.
Panel Unlock
The communicator must be in an unlocked state to accept a remote upload/download. Entering the
4 digit code will unlock the panel for a period of 30 minutes, unless otherwise programmed.
Time-out at 411UDAC
Upon answering an incoming call on the primary Central Station phone line, the communicator will
listen for a modem connection signal. If this signal is not received within 30 seconds, the commu-
nicator will disconnect the call. Upon successful connection (i.e. secret code verified and callback
complete if applicable), if no communication occurs within two minutes, the communicator will
disconnect the call.
