Backup Battery; Earth Ground - Honeywell ADEMCO VISTA-12A Installation And Setup Manual

Installation and Setup Guide

Backup Battery

1. Place the 12-volt backup battery in the cabinet.
2. After all connections to the control are
completed and AC mains power has been
applied, connect the red and black flying leads
on the control board to the battery. Do not
attach these leads to the battery terminals until
all connections are completed.
Battery Saver Feature: The battery will
disconnect from the system after its voltage
decreases below 9VDC. This assists the control
panel in recharging the battery when AC is
restored.

Earth Ground

Metal Cold Water Pipe or Earth Ground Rod:
Use a non-corrosive metal strap (copper is
recommended) firmly secured to the pipe/rod to
which the ground lead is electrically connected and
secured.

Notes
IMPORTANT: The panel will not power up
initially on battery power only. You must plug
the transformer in first, and then connect the
battery.
Operating on Battery Power Alone:
To operate the control on battery power only,
connect a jumper between the negative (–)
battery terminal and control PCB terminal 4
(– aux power).
Notes
• This product has been designed and
tested to ensure its resistance to damage
from generally expected levels of
lightning and electrical discharge, and
does not normally require an earth
ground.
• If an earth ground is desired for
additional protection in areas of severe
electrical activity, terminal 25 on the
control board, or the cabinet, may be
used as the ground connection point.
The examples of good earth grounds
listed at the left are available at some
installations.
