This document is the first part of the user guide for ADEMCO VISTA-12A and ADEMCO VISTA-12E security systems. The document covers system compatibility notice, basic features, arming modes, disarming and silencing alarms, and other non-alarm functions.
This guide provides an overview of the Honeywell VISTA-12A/E security system, describing burglary system features, partition and zone concepts, and how to use the keypad for arming, disarming, and accessing voice functions. It also details exit/entry delays, bypass procedures, and basic arming modes such as Stay, Night‑Stay, Away, and Maximum.
Additional sections cover troubleshooting, alarm silencing, and the one‑year limited warranty, helping installers and users maintain reliable operation of the security system.
A rapid beep means an alarm occurred while you were away and an intruder may still be on the premises.
Enter your security code followed by the [3] key (STAY).
Press the security code, then [6] BYPASS, followed by the two‑digit zone numbers you wish to bypass.
