I am trying to assemble a circuit using 12 volt Energizer A23 batteries as a backup. If switch 2 is opened, I would like the alarm and light to activate even if there is a loss in power.
1) Is the attached circuit functional?
2) The capacitor raises the voltage to the voltage regulator near the max for the voltage regulator.
a) Is the capacitor necessary for the circuit? If it is, would a smaller capacitor be sufficient?
b) Is the voltage regulator adequate for the circuit?https://www.fairchildsemi.com/ds/KA/KA278R05C.pdf
