The old obsolete LCN 7910-931 receiver can be powered off the Sr Swing control boxes made Dec. 9, 2019 or later because the CB low voltage output is 24VDC, 1A current draw.
BUT it should not be powered off a Sr Swing Control Box made prior to Dec. 9, 2019. Why -- The older CB power output was 24Vac which is incompatible with the receiver (7910-931) voltage of 12-16Vac or 12-24Vdc.
