Customer Question
Ademco vista 20. Just moved...
Ademco vista 20. Just moved in house a year ago. I plugged system in and always said ready with green light. If door opened the green light would go off. I wanted to start using it. I'm not connected to phone line. I tried to find code on line. Hoping there was a default code. I read power off and on press#* till code 00 or 20 comes up. Mine said 00. I pressed #20. Goes ready no code comes up and now goes armed.

Hi Mike,

Electronics Technician: Pete, Electronic Engineer replied 2 years ago

If you have forgotten the code to arm/disarm the alarm system, then you will need the installer code to reset it.

The installer should have a note of the installer code if you don't have it available.
