bash Posted April 15, 2009 Share Posted April 15, 2009 Hi We came back from holiday and the alarm was going off. Later found that the fuse had turned off and so running on battery power. However we could not input our code into the keypad as I think the battery must have died. Tried to turn the fuse back on but then the alrm just went off so had to turn fuse off and diconnect battery also. But since replacing battery, the key pad has a fault message on it and I cannot seem to enter the code (or the engineers code) to reset it...any clues the error meesage is.... num check fault follwed by system lockout... have tried all above steps again but it eiether justs goes off (when tripping fuse) or back to error message....??

aismoresecur Posted April 15, 2009 Share Posted April 15, 2009 Sounds like the system has crashed or problem with NVM chip Link to comment https://www.thesecurityinstaller.co.uk/community/topic/28177-karizma-plus-system-lockout-query/#findComment-233377 Share on other sites More sharing options...
Guest RJBsec Posted April 15, 2009 Share Posted April 15, 2009 ADE product left on battery only = problem, you need a local installer to call.

chexsec Posted April 15, 2009 Share Posted April 15, 2009 A checksum error means the data in the NVM (Non volatile Memory) chip is corrupt and doesn't match expected values. The panel needs defaulting and reprogramming. The engineer code may have been corrupted. So much for "NON VOLATILE" memories Also get the alarm connected to it's own mcb in the dis board.
