VISTA-10SEa Installation and Setup Guide
The length of all wire runs must not exceed 450m when unshielded quad conductor cable is used
(225m if screened 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 size determined in step 1).
3. Connect remote keypads to terminals 4, 5, 6, and 7 on the control board.

Mounting the Keypads

1. Make sure keypads 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.
Refer to the mounting instructions and template included with the keypad for specific
information.

Supplementary Power for Additional Keypads

The control provides 500mA for powering keypads (up to 4) and other devices from the
auxiliary power output. The backup battery will supply power to these keypads in the event
that mains 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.
Keypads powered from supplies that do not have a backup battery will not function when mains
power is lost. Therefore, be sure to power at least one keypad from the control's auxiliary power
output.
Connect the additional keypads as shown in Figure 3-2, using the keypad wire colors shown.
Be sure to observe the current ratings for the power supply used.
Make connections directly to the screw terminals as shown in Figure 3-2. Make no
connection to the keypad blue wire (if present).
Be sure to connect the negative (–) terminal on the power supply unit to terminal 4 (AUX –)
on the control.
