Electronic Alarms and Home Security Devices - Ademco Vista 40 Installer Code?

My wife has a business that just moved into a new complex. It has an Ademco Vista 40 Alarm system. The previous tenants skipped out without paying rent and we cannot get the alarm code for the panel. Is there anyway to change the installer code to re-program the unit. I have downloaded the installation manual, but it states the default installer code is 4140. The person(s) who installed this have changed the default code. The number on the circuit board is
SA 4142-4H. Two other numbers are WB 091 and X117.

Any help is much appreciated.

Thanks,

Kevin

From the sticky:

"Retrieving Installer code
Nearly all Ademco family (this includes First Alert, Security Link, and several ADT models) panels can retrieve the Installer code by disconnecting the battery, then the AC power. Wait a minute, then reconnect power in the opposite order. Within 50 seconds, on any keypad press * + # at the same time. Unless the system has had an installer lockout feature activated, the panel should go into program mode. The details by system will vary, but the programming section number that shows on the display will be the location for the installer code (on _most_ panels this will be 20). Key in # and the location number, and the panel will read back the installer code one digit at a time. Exit program mode using *99."

Thank-you I will try this.

Next time I will read the "Alarm Forum FAQ" before I bother people with my posts.

In the case of your system, the location will be 00.

There is a seperate programming location form for this system, it your manual download didn't include it, you will likely need it as well.

Thank-you for the update, I have also downloaded the programming guide.
