Hi,
I've had a Napco Magnum 1000 for about 16yrs already. Overall, the system
works perfectly well - everything it was setup/designed to do is precisely
the way it works. Except for one thing.
The daily phone verification has a problem and has always had this problem
since day one. Ever since the system has been installed, the clock seems
to
drift a second or so every day. If the system is programmed to dial out
at
4am, every few months (never really checked it carefully, but might be a
question of 6-8 months or so), it drifts back to 9pm or 10pm where it
becomes a nuissance to the people living in the house. At which point,
the
dial out timer has to be reset back to 4am, and that works for another
series of months before the same issue repeats itself.
I was wondering if anyone else has ever encountered that kind of issue in
the past, and if so, what can be done to rectifiy it, instead of having to
manually reset it every time it drifts too much.
Can a faulty/flaky transformer be responsible for something like this? I
know in theory it shouldn't, if the crystal on the board responsible for
the
digital clock is accurate, but I'm out of ideas. The whole alarm system
is
on a UPS, so I am certain that the input current is glitch free.
Any thoughts?
Thanks!
Eric
