DSC Zone Fault

[Jmonty]

I have a customer who has a DSC 5010 panel, with a 5132 wireless interface.
He has only wireless zones on this system 8 to be exact. One zone, which is
a wireless door contact developed a zone fault. When I went to the residence
and check it, everything seemed in order and the signal it sent was
excellent. I replaced it. Now 2 months later...same zone...same thing. Again
I tested and it has an excellent signal. No other problem have occurred on
this system. Has anyone else experienced anything like this?

Let me be the first to tell you I have no idea why this would be happening.
However, the 832 is a good panel, but does tend to due odd things on
occasion with the wireless supervision side of things. Perhaps there are
others on the NG with more experience on the 832 who know exactly why this
is happening, but two last resorts to check might be to:

1- check the plastic cover attachment tab on the wireless door contact.
Maybe it's coming loose and sending a tamper? (I had this happen to me)
2- If all else fails, software default and reprogram. I have found this will
sometimes cure those wierd wireless supervision signals that can't be solved
any other way (don't ask me why !!)

When you replaced the transmitter, did you power down & reset the
supervision? (902)...If this doesn't fix the problem, reset the 5132 (996),
and reprogram the sensors again. You don't really need to wipe the entire
panel. Also make sure your zone attributes are set correctly (101-108...)

Is the transmitter on the door, and the magnet on the frame ?

AH HA! as Paul might say.

Have you determined if the loss of supervision occurs at a particular time
of the day? Or have you tried to correlate the loss of supervision with some
event in the premise or in the surrounding area? Is there a ham radio
operator in the vicinity or some source of RF out put that could be causing
a problem? (police car or station, taxi cab or business with short wave
radio, etc) Take a line of sight from the transmitter to the receiver. Is
there any type of large metal object or source of RF in the vicinity of this
path? Have you tried relocating the receiver or adding a receiver to the
installation?

I had an installation once where I was getting intermittant supervisory
signals. I had put the upstairs receiver ( I almost *always* use two
receivers on every job) in a closet. The lady of the house chose the top
shelf, right next to the receiver, to store her clothes iron. Every couple
of weeks, she would put it in the closet for a few days and the rest of the
time it would stay by the ironing board. It only affected a couple of the
transmitters and not the same ones each time or somtimes none were affected.
Working with RF is 25% skill and experience the rest is trial and error and
magic.

Listen to Jim,
I had a wireless motion do the same thing to me. I did the reverse and
reprogrammed the panel to no avail. I did the 5132 reset and it solved my
problem. Don't forget the 902 after the reset. (I did)

-or- is the transmitter placed in such a way that moisture can get to it?

If its not programming"
Loose cover,
transmitter on wrong (door instead of frame and getting a little abuse)
transmitter sucking a little moisture

Replace the sensor, its possible you have older DSC wireless, zone faults
were common with those

The door it is on is a nook porch that is covered...doubtful it is
moisture...as far as a loose cover I think it would show a tamper instead of
a fault.

I'm not up on DSC wireless, but if a zone fault here refers to a supervisory
window and you've tried more than one transmitter in the same spot,
re-locate either the transmitter or the receiver. Alarm transmissions are
multiple and more likely to get through every time, check-ins are singular;
some (in your case, many) don't make it.

Sounds like your getting interference in that area that the panel
recognized, too bad Paul can't see this

[Jackson]

To the original poster :

When you put the transmitter on the door, and the door gets slammed hard
enough, the battery connection will become loose and the receiver will
generate a fault signal half a day later.

Solution, move the transmitter to the frame side and hot clue the batteries
to the holder.

I don't know what the design engineers from DSC had in their mind when they
design the wireless unit to work with multiple units of AAA batteries. Their
wireless motion detectors have similar problem (not checking in) due to the
cheap metal clips not making proper contact with the battery terminals in
the battery compartment.

I think they fixed that in the later models, while at Westinhouse we used to
have endless problems with zone faults on the original wireless devices, in
the last 2 years this has almost disappeared

I've heard of that happeniong when an installer puts the magnet on the frame
and the xmitter on the door.

When the door slams, the spring compresses just enough to cause a tamper.

Yup, coupled with that bizarre 1st generation design caused tons of problems

I have not worked on many DSC systems but just off hand I would test the
mag. If mounted on a steel door or frame I have seen the mags loose power
before and cause this same problem. I chased a mag problem on a ITI system
though 3 transmitters before I changed the mag problem went away. Just a
thought, hope it helps.

That's those cheap ITI magnets. Use real magnets and recess them. Sentrol
makes great steel door magnets as does GRI.

That won't cause a zone fault, DSC uses that term to mean problem with a
transmitter, wish they'd just call it zone TROUBLE...damn canadians....oops
sorry Robert! :)

Actually the "sorry Robert" was directed to Robert Campbell but if your
Canadian it would be meant to you as well :)
