2. The power supply as recited in claim 1 , including a regulator receiving energy from the first energy store and communicating that energy to the processor.
3. The power supply as recited in claim 2 , including a charge control governing charging of the second energy store.
4. The power supply as recited in claim 1 , wherein a ratio of the second energy storage capacity to the first energy storage capacity is between 10 to 1 and 1000 to 1.
5. The power supply as recited in claim 1 , wherein a ratio of the second energy storage capacity to the first energy storage capacity is between about 1000 to 1 and 10,000 to 1.
6. The power supply as recited in claim 1 , wherein the first energy store charges to the first energy storage capacity within a first time and the second energy store charges to the second energy storage capacity within a second time that is longer than the first time.
7. The power supply as recited in claim 1 , wherein the second energy storage capacity stores enough energy to operate the processor through an extended power interruption.
8. The power supply as recited in claim 1 , wherein the second energy store charges the first energy store in response to an extended power interruption.
9. The power supply as recited in claim 1 , wherein the processor governs operation of at least one of a horn and a strobe.
10. A notification appliance circuit (NAC) comprising:
a plurality of notification appliances, wherein at least one of the plurality of notification appliances include a power source including:
a first energy store having a first energy storage capacity;
a processor powered by energy from the first energy store; and
a second energy store having a second energy storage capacity greater than the first energy storage capacity, wherein the processor delays charging of the second energy store after a delay beginning at a time of receipt of a charge of predefined level from the first energy store; and
circuit wiring connected to provide electric power to each of the plurality of notification appliances and synchronize operation of the plurality of notification appliances.
11. The notification appliance circuit (NAC) as recited in claim 10 , including a regulator receiving energy from the first energy store and communicating that energy to the processor and a charge control controlled by the processor for governing charging of the second energy store.
12. The notification appliance circuit (NAC) as recited in claim 10 , wherein a ratio of the second energy storage capacity to the first energy storage capacity is between 10 to 1 and 1000 to 1.
13. The notification appliance circuit (NAC) as recited in claim 10 , wherein a ratio of the second energy storage capacity to the first energy storage capacity is about 1000 to 1 and 10,000 to 1.

16. The notification appliance circuit (NAC) as recited in claim 10 , wherein the second energy store charges the first energy store during an extended power interruption.
17. The notification appliance circuit (NAC) as recited in claim 10 , wherein at least one of the notification appliances include at least one of a horn and a strobe.
18. A method of powering notification appliances in a notification appliance circuit (NAC) comprising:
charging a first energy store within the notification appliance with an input current from an NAC; and
charging a second energy store within the same notification appliance after a delay period beginning at a time of receipt by a processor of the notification appliance of current at a predefined level from the first energy store.
19. The method as recited in claim 18 , including setting a regulator start with a processor in response to receipt of charge at the predefined level.
