How Do I Turn Off Arm-Confirm for a Honeywell VISTA System?
You can turn off Arm-Confirm for a Honeywell VISTA System by using the *38 command in programming. You will need the Installer Code to access this setting. Each partition has its own setting. Once Arm-Confirm is turned off, your system's siren will no longer "ding" whenever you Arm Away.
The purpose of the Arm-Confirm setting it to alert you that the system has been Armed Away so that you know to exit the building. This can be very important for preventing false alarms. If the setting is enabled, and the system is Armed Away using a keypad or key fob, then the siren for the system will produce a quick "ding" sound. This sound is nothing more than a short burst, and it is just to let you and everyone else know to exit the building immediately.
However, some people find the Arm-Confirm sound to be annoying, and they want some method for turning if off. Fortunately, the sound can be turned off quite easily. You just need to disable the Arm-Confirm feature by accessing the *38 setting in programming. By setting *38 to  for each partition, you will disable Arm-Confirm for the system.
Complete the following steps to turn off Arm-Confirm for a Honeywell VISTA Security System:
1. Enter programming. Enter the command [Installer Code] +  to access programming. Remember that the default Installer Code for a Honeywell VISTA System is 4112. Assuming your system has the default Installer Code, the command to enter programming is  + .
2. Access *38. Enter [*] + . This will have you access the *38 field, which is used for turning the Arm-Confirm setting ON and OFF. The setting is adjusted individually for each system partition.
3. Turn OFF Arm-Confirm. For Arm-Confirm 1 = ENABLED, and 0 = DISABLED. Assuming you want to turn it OFF across the entire system, enter  for each partition. If you have a two (2) partition system like the VISTA-20P, you will enter  + . You cannot adjust the setting for a common partition, so those will be automatically skipped. Once you make the final entry, the system will beep to confirm, and you will be taken to the next programming field in the sequence, which is *39.
4. Exit programming. Press [*99] to safely exit programming. Always use that command to exit programming, as using a different method could cause you to become locked out later on.
