This section lists the wired keypads that may be used and provides
instructions for wiring and mounting the keypads.
A preliminary check-out procedure is also provided to ensure that the
connectedkeypadsarefimctioning properly in the system.

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
separatelyfkomthosekeypadaconnectedto Partition 1.
For devices(Keypads,RF Receivers,Zone Expander, etc.)connectedto 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
Section
14.F~AL POWER UP for current draw for all keypads.
