Strange DSC 832 behavior

[Bobby_M]

I'm totally lost. I have an all-hard wired 832 system with one
expansion board. I have 7 magnetic contact perimeter zones, one window
bug (vibration) on my sliders, and 4 motions that are set as inide
zones.

Last night, my alarm woke me up at 2am, siren blasting. I got up and
looked at my bedroom keypad and it did not indicate any zones that were
responsible for the alarm condition. I haven't tested the system in a
while, but I recall that the keypad displays and cycles through each
tripped zone both during the alarm, and after the swing.

I disarmed and it didn't show me any tripped zones in memory.

Any ideas what's going on? This is the second time this has happened,
the first time was over a year ago.

I know the system monitors for dial-tone because i've heard the keypad
complain "error" when I work on my phone line but this has always been
in a non-armed state. Does the system alarm if it loses dial tone when
armed?

Programming section 15, # 8 will determine if the TLM is audible or not
when armed
Also if you have an LCD keypad then you should look in the event buffer,
this may show the event that caused the alarm

Yes, if you have TLM enabled a problem with the phone line will cause an
alarm. The panel cant tell the diffrence between someone cutting your line
and a glitch at the telco switch. Its all the same to it.

If you want it off its section (015) turn off #7

Blame your telephone company. They're usually working (or upgrading) on the
lines in the "wee hours" when people aren't supposed to be using their
phones... I wouldn't disable the line monitoring feature though... It's
often your "first line" of defence. The "perp" will probably cut your lines
before he tries to gain entry into the house...

No, that will disable TLM entirely, which is not a good idea.

Just turn off bit 8 in section 015 to avoid the siren, as Doug already said.

Thanks for the replies. I suspected there was a programming option to
disable TLM but it's been over a year since i've programmed the system.
If i disable the siren for TLM, will I still get the beep out of the
keypad at least to tell me the line is having problems? I agree that I
want to know when the line has issues, but I don't need that heart
attack everytime someone monkey's with the lines down the street.
Interestingly enough, this explaination is supported by the fact that
my neighbor does not have a working phone today.

Will the event log show that the TLM was the cause of the alarm? I do
have the fixed LCD keypads.

Turning off bit 8 in section 015 will disable the siren on TLM. As long as
bit 7 is on, you still get the trouble light and beeps. The event log will
register the TLM fault.

Fabulous, thanks... Time to dig out the user manual.

Fabulous, thanks... Time to dig out the user manual.

Umm that won't be in the user manual

 

[alarman]

Fabulous, thanks... Time to dig out the user manual.

It's not in the user manual.
But why would you look it up now anyway? We've already answered your
question.

Sorry i should have clairfied that a little better. I meant if TLM was
enabled it will generate an alarm while armed if the phone line dropped.
That was just a way to turn it off if its not monitored. I wouldnt ever tell
someone to turn that off. Unless its a local system only.

Sorry my bad

 

[Bobby_M]

I didn't mean the user manual, I meant the installer's programming
guide or whatever it's called. I don't remember the exact process of
getting to the programming section by memory because I last messed with
the programming over a year ago. I'm sure it will come back to me
because I installed and programmed the system initially. Again, thanks
for the help.

If your TLM is enabled and the alarm is set for the night, any phone outage lasting about 30 seconds will set the sirens off.It doesn't show up on the key pad, so a *2 on the keypad might help track down the problem.
