Advent Commercial Fire System
Determining Maximum Panel Wire Length
Example:
Using 22 gauge wire to connect the following devices on
one wire run (length of cable):
Device Current Draw
(see note)
1- Hardwire 2-Line Alpha Touchpad = 120 mA
1- RF Transceiver Module = 50 mA
1-8Z Hardwire Input Module = 35 mA
Total Device Current Draw = 205 mA
Find the total device current draw in the table and match the
wire type used. In this example, the maximum recom-
mended wire length is about 154 feet. For longer lengths,
use a larger gauge wire.
Note
For self- or remotely-powered devices, the maximum rec-
ommended wire length is 4,000 feet using 22 gauge or
larger wire.
