Ac Transformer And Battery; Panel Earth Ground Connections - ADEMCO VISTA-128B Installation And Setup Gude

VISTA-128B Installation and Setup Guide

AC Transformer and Battery

This product uses the 1361 transformer (1361CN in Canada). We recommend wiring all
zones and expansion modules according to each section's instructions before powering up the
system for programming and testing. Refer to the Final Power-Up Procedure section for
specific instructions on how to connect the transformer and backup battery.
If using Powerline Carrier devices, the 4300 transformer interface must be used instead of
the regular 1361 transformer. The 4300 supplies the control panel with AC, and also sends
control pulses through the premises electrical system to control the Powerline Carrier
devices. Refer to the Final Power Up Procedure for specific instructions on how to connect
the 4300 transformer.
Refer to the Final Power-Up Procedure section for battery standby calculations and battery
selection table.

Panel Earth Ground Connections

In order for the lightning transient protective devices in this product to be effective, the
designated earth ground terminal (terminal 30) must be terminated in a good earth ground.
Recommended wire gauge for the ground connection is #16 AWG run no further than 30 feet.
The following are examples of good earth grounds available at most installations:
•
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 three-wire circuit tester with neon lamp
indicators, such as the UL-Listed Ideal Model 61-035, or equivalent, available at most
electrical supply stores.
The panel requires this connection in order for its lightning transient protection devices.
