Narrative:

We received an ECAM advisory of smoke lavatory and cargo detection fault, which means we had no detection of smoke or fire in any lavatory or cargo compartment. Company policy states that we are not to reset breakers to restore system function in-flight, unless we use 'captain's emergency authority/authorized' to do so. We were over landing weight, and I conferred with maintenance, and decided to reset breakers as a safer course of action to restore system function, than to fly with no smoke detection. This happened 14 mins out of dca. Because of security reasons, and being overweight (landing weight), it seemed prudent to try to restore system function, which we did. All operations normal for rest of flight.
