Backup Battery; Earth Ground - ADEMCO VISTA-20PS Series Installation And Setup Manual

Backup Battery

1. Place the 12-volt backup battery in the cabinet.
2. After all connections to the control are completed and
AC 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.
CALIFORNIA STATE FIRE MARSHALL (CSFM) AND UL RESIDENTIAL FIRE
The California State Fire Marshal and UL have regulations which require that all residential fire alarm control
panels must be provided with a backup battery which has sufficient capacity to operate the panel and its attached
peripheral devices for 24 hours in the intended standby condition, followed by at least 4 minutes in the intended
fire alarm signaling condition. This control panel can meet these requirements without using a supplementary
power supply, provided that the panel's auxiliary power and bell output currents are limited as indicated below.

‡ NOTE: Use two batteries, connected in parallel. Obtain an Ademco Battery Harness Kit SA5140-1. (Both batteries
will fit inside the panel's cabinet.)

Earth Ground

Metal Cold Water Pipe:
Use a non-corrosive metal strap (copper is recommended)
firmly secured to the pipe to which the ground lead is
electrically connected and secured.
AC Power Outlet Ground:
Available from 3-prong, 120VAC power outlets only. To
test the integrity of the ground terminal, use a 3-wire
circuit tester with neon lamp indicators, such as the UL
Listed Ideal Model 61-035, or equivalent, available at
most electrical supply stores.

In UL installations, maximum current draw from the Auxiliary Output and the Alarm Output combined must not
exceed 600 mA (500 mA max from Auxiliary Output).

IMPORTANT: The panel will not power up
initially on battery power only. You must plug the
transformer in first, and then connect the battery.

Notes
• This product has been designed and laboratory-
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 most installations.
