I have a DSC 1832 alarm with a 5500 keypad. This is connected to my home phone to make an outgoing call to my and my wife's cell phone if the alarm is triggered. This has worked for the last 2 years but the phone company changed my cell phone number.

The company that installed the alarm is no longer in business and I need help reprogramming the phone number into the alarm.

I found a copy of the Installers Technical manual but, unfortunately, it is a bit too technical for me. I can make normal changes like the time, add / delete users etc.

If someone could give me the keystrokes to use change the numbers I and the person who now has my old cell phone number will be very grateful.

Thanks,

Dave
