If you want a technical argument about how the electronics of a system work then start a new thread. (he won't).
Do you remember writing this Saxo? (about your abilities)
"thanks Bernard as you have worked out I`m not nor ever claimed to be technically knowledgable to your level, just someone out in the field making these devices work"
and whats that got to do with experiance (and keeping records) ?
fact is we (that is full time alarm engineers) change more batteries than any other device on a system, either during a service visit or due to a call out, the most comman manifestation of a bad battery on an older system ( as indeed this panel design is) is a tamper signal
if the age of the system is unknown ( ie a new occupier etc ) then a new battery is always fitted during the first service visit
it really is that simple
bell box tamper ? pah why`s it not going off when its set hmm ?
