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: 6127, 6128, 6137
• Alpha Display: 6138, 6139
• Up to 4 keypads, independent of auxiliary power considerations (you may need to use an
auxiliary power supply if the 500mA aux. output is exceeded)
If you are going to use a 4285/4286 VIP Module, you MUST use addressable keypads (6128,
6137, 6138, 6139) in the system, but set to the non-addressable mode (address 31).
Wiring to the Keypads
1. Determine wire gauge by referring to the wiring length/gauge chart below.
For devices (keypads, RF receivers, 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 the
SPECIFICATIONS & ACCESSORIES
section.
NOTE: Refer to “Auxiliary Device Current Draw Worksheet” in the
FINAL POWER-UP
section for current draw for all keypads.
Maximum wire lengths for any device that is homerun to the control can also be determined
from the chart, based on the current draw of that device
alone
