摘要： A notification appliance circuit (NAC) includes notification devices having a high capacity rechargeable energy storage device such as a supercapacitor and a strobe circuit. The supercapacitor can provide energy to produce flashes over an extended time period without fully discharging. The notification devices can also make use of the fallback power strategy in which the strobe circuit operates with reduced intensity while the supercapacitor is being recharged.
