Local/Remote Site Upload/Download
132 MS-5UD/MS-10UD Series PN 52626:B 8/01/2008
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 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.
