7847i/7847i-E Installation and Setup Guide
Wiring the 7847i/7847i-E
Unshielded, 22 AWG cable is recommended for 7847i/7847i-E power/data wires.
Wiring for ECP, 4204 and Two-4204 Modes
Most Honeywell ADEMCO control panels support LRR-ECP data communication, (e.g.,
VISTA-10P,
VISTA-128FBP/250FP). However, there are some panels that do not. Check the Installation
and Setup Guide for the control panel you are using to see if it supports ECP communication.
Connect the 7847i/7847i-E to a compatible Honeywell VISTA control panel's ECP terminals,
in parallel with keypads and other peripheral devices, VIP module, etc. Wire length/gauge
limitations are the same for the module as they are for keypads and other peripheral devices.
To wire the module for ECP communication, see Figure 3 and do the following:
To install a 7847i/7847i-E with a LynxR-I Security System, wire the devices as shown in
Figure 4 below. Refer to LynxR-I Installation and Setup Guide.
