Car Alarms: Automate RPN491 in 99 Jeep Cherokee, jeep cherokee, alarmtek

Question
I bought my '99 Jeep Cherokee 1 year ago.  The first time the alarm went off, I disabled it using the button under the dash.  The alarm light went out and stayed that way for a year - just the way I liked it.  Suddenly, today, like the Terminator, the thing came back to life and has gone off a couple of times, scaring the socks off of people and creating a nuisance.  I want to disable it.  How do I do that?

P.S. - It seems impossible to find any information online about this particular car alarm.  Please help!

Answer
Please, if you would, restate this question
in my installers forum at www.installsupport.com
and see if my resident technician there can assist
with this project. (ask for Robert!)

This is a DEI product, and he's your man
on this one.

Good luck there.
