VISTA-10SEa Installation and Setup Guide
Example:
If total auxiliary device current drain is 450mA, add 100mA for the control panel, for a total
of 550mA (0.55 amps). If you want 24-hour standby, the calculation will be:
In this example, two 7 Amp/Hr batteries (connected in parallel) must be used.
Making the Battery Connections
1. Use the battery standby formula (shown above) to select the appropriate battery for the
installation. Remember, when calculating the battery size needed, you must add the
100mA used by the control itself to the total auxiliary current drain in the worksheet on
the next page.
Do not connect to the battery until all devices have been wired to the control.
2. Attach the red and black wires of the battery connector cable to the battery, as follows:
a. Red to the positive (+) terminal on the battery.
b. Black to the negative (–) terminal on the battery.

0.55mA x 24 hours = 13.2 Ampere/Hour battery needed.
