Section 3. INSTALLING REMOTE KEYPADS
This section lists the wired keypads that may be used and provides instructions for wiring and mounting the keypads.
A preliminary
Keypads That May Be Used
•
•Alpha Display: 5137AD, 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 Phone module, you MUST use addressable keypads (4137AD, 5137AD, 6128, 6137, 6138, 6139) in the system, but set to the
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
Note: Refer to “Auxiliary Device Current Draw Worksheet” in theFINAL 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.

*Includes Keypads, RF Receivers, Relay Units, or 4285 Phone module.
The length of all wire runs must not exceed 1500 feet (457m) when unshielded quad conductor cable is used (750 feet if shielded cable is used). This restriction is due to the capacitive effect on the data lines when quad cable is used.
2.Run field wiring from the control to the keypads (using standard 4- conductor twisted wire cable using the wire gauge determined in step 1).
3.Connect remote Keypads to terminals 4, 5, 6, and 7 on the control board, as shown in Figure 5.
