Hey, I have the above alarm panel and sector five seems to be fried, there are a couple of fried 1n4746 diodes also on the board which I add up guessing to be related to sector five having no led status. The point being I am tring to get this panel to work,and would like to know if having sector 5 burnt out???? will cause the whole code to be corrupted and not work. As per MCM manufacture info sheets,the panel will factory default upon bootup with five beeps if the code has been corrupted,which it dose,this panel also came with a blown plug pack...lol...hmmm.
Dose anyone recon I need sector five working to get this thing opperational,I cannot enter programming mode,therfore my assumption of eprom code not liking sector five missing?
I will attempt to add some new diodes and plugpack however,again,should one sector missing stop me from entering programming mode?...iffy question I guess.
