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.
