General Information
This section lists the wired keypads that may be used and provides instructions for wiring
and mounting the keypads.
A preliminary checkout procedure is also provided to ensure that the connected keypads are
functioning properly in the system.
Keypads That May Be Used
• Fixed-Word Display: 6128
• Alpha Display: SK6139A-BAY
Up to 4 keypads may be used in the system, independent of auxiliary power considerations
(you may need to use an auxiliary power supply if the 600mA aux. output is exceeded).
Be sure all keypads are set to the non-addressable mode (address 31).
Wiring to the Keypads
1. Determine wire gauge by referring to the Wiring Run Chart below.
For devices (keypads, RF receivers, zone expander, etc.) connected to a single 4-wire run,
determine the current drawn by all units connected to the single wire run, then refer to
the Wiring Run chart to determine the maximum wire length that can be safely used for
each wire size. Current draw for all devices can be found in
Section 26: Specifications
& Accessories
.
NOTE: Refer to Table 1. AUXILIARY DEVICE CURRENT DRAW WORKSHEET in
Section 13: Final Power-Up to obtain the current draw for all keypads.
MAXIMUM wire lengths for any device that is homerun to the control can also be determined from
the Wiring Run Chart, based on the current draw of that device
alone .
