Trying to wrap my head around it

[JoeRaisin <joeraisin2001@xxxxxxxxx>]

Had a service call that has me scratching my head.

Monday the customer kept getting calls from the monitoring center saying
they were getting a fire trouble on zone 5.

Panel is a Safewatch 3000.  Zone 5 is an entry/exit point programmed
correctly.  There are no fire devices on the system and no unused zones
are programmed as fire though they are programmed and resistored out at
the panel.

The customer is using phone service through their cable company and
their data guy was on site during the time they were getting these calls.

I had heard some time ago about ADT monitoring centers seeing telco line
faults as a fire trouble (why, I don't know) so that could explain the
fire trouble, but they insist it was coming in on zone 5.

The zone 5 part is what bothers me.  I don't like not understanding
something.  If it was a one time signal I could let it go as a an
electron forgetting to turn left at Albuquerque - but it happened
several times throughout the day (my guess would be every time the data
guy fucked with the cable/phone equipment).

I checked the program and ran the system through its paces and
everything is (and 'was' as far as I could tell) programmed and
functioning correctly, btw.
