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.

Mounting the Keypads

1. Make sure addressable-type keypads (6128, 6137, 6138, and 6139) are set to non-
addressable mode (address 31), which is the factory default setting. Refer to the
instructions provided with the keypad for address setting procedure.
2. Mount the keypads at a height that is convenient for the user. Refer to the instructions
provided with the keypad for mounting procedure.
You can either surface mount or flush mount keypads (using an appropriate Trim Ring
Kit: 6139TRK). Refer to the mounting instructions and template included with the
keypad and/or trim ring kit for specific information.

Supplementary Power for Additional Keypads

The control provides 500mA for powering keypads (up to a maximum of 4) and other devices
from the auxiliary power output. The backup battery will supply power to these keypads in
the event that AC power is lost.
When the control's auxiliary power load for all devices exceeds 500mA, you can power
additional keypads from a regulated, 12VDC power supply (e.g., 487-12 supplies 12V, 250mA;
488-12 supplies 12V, 500mA). Use a UL Listed, battery-backed supply for UL installations.
The 487-12/488-12 power supplies have a backup battery that can power these keypads in the
event of AC power loss.
