Ademco Ademco VISTA-20se/VISTA-20HWse Beeping

I have read many postings, but have not seen my specific problem. I have Ademco VISTA-20se/VISTA-20HWse, I have User's Manual and my code. It is 15 years old, I am the only owner, it is plugged into a landline phone jack, it has a new battery. The keypads (2) will randomly beep and will turn off upon pressing any button. The keypads will stay silent for a few minutes, or weeks or months. I do not have monitoring. The error code is 04, one of the zones that has a sliding door with 2 3 dimensional rectangular contacts, and 2 windows with a disc contact / magnet ? The system is hard wired. I have tried bypassing Zone 4 with no luck. I've had this problem with both the old battery and new. An electrician / former alarm guy thought it could be the door/window contacts, but bypassing them should solve the problem. After entering my code and off 2x's I get a green ready light and no error code displayed, but beeping eventually returns.

Any ideas? Thank you.

If the only thing showing is 04, then it's just an open zone. It could be a contact on the edge of the magnetic activation range, and once in awhile, the right vibration triggers it; or it could be a cable with a bit of damage somewhere in the attic/wall; or it could be the zone input starting to fail.

With the information provided, it's hard to do more than guess.

Remember, hardwired door and window contacts are just magnetic switches.
