Table F describes the recommended maximum distances for 24 VAC applications, which are calculated
with a 10 percent voltage drop. (Ten percent is generally the maximum allowable voltage drop for
AC-powered devices.)
NOTE: Power consumption is 21 VA per unit. Use a power source with a minimum of 21 VA per unit.
