dealer data sheets) for the 4208U.  All zones 10-16 on the 4208U show fault=
s=2E  For zones 10-16 I have the switches set for ON ON ON ON OFF OFF OFF O=
N, and zone type (50P) set for #7 (programmed zone by DIP Switch).  I even =
connected the EOL directly to loop B and it still gives me the fault readin=
g=2E  Can the panel lose it's programming for those zones, or did the origi=
nal owner never have the expansion zones turned on? as I had to enable them=
.  I'm currently testing the alarm with only 1 7amp battery, and 3 keypads =
(using a sonic alert as a temp siren (instead of the MVA1000 and 4 speakers=
)) so I don't think I have a current problem.  I also put a jumper across t=
he tamper switch, as it appears that the magnet (if there is one) in the 42=
08 cover is missing (although switch 8 should bypass it).  Since loop A is =
not used, I didn't put an EOL on it.  Is there an additional memory locatio=
n in the 50P to tell the system that a 4208 is installed?
