W~To The Keypade
1. Determine wire gauge by referring to the wiring lengtldgauge chart
below. Wire lengthdgauge for Partition 2 keypads should be determined
separatelyfkomthosekeypada connected to Partition 1.
For devices(Keypads,RF Receivers,Zone Expander, etc.)connected to a
single 4-wire run, determine the current drawn by all units connectedto
the single wire run, then refer to the Wiring Run chart to determine the
maximum wire length that can be safelyused for eachwire size. Current
draw for all devices can be found in the SPECIFICATIONS AND
ACCESSORIES section.
Note Refer to "Auxiliary Device Current Draw Worksheet" in
