After changing the system battery on our ADT alarm panel the default settings took over. The voice was turned on for every zone fault and we wanted to turn this feature off. It was very difficult to find this information, so once we found it we wanted to share it with others who might have the same issue. Portions are pixelated for privacy.
The correct manual with this information is called
Safewatch Pro 3000EN
Entrepreneur 3000EN
Security Manager 3000EN
and was published in June 2002. Relevant pages 7 and 22.
