There is no codes requiring that you replace your entire system after a certain amount of time. All smoke detectors should be replaced after about 10 years, but most fire inspectors won't do much. As long as it works and passes its quarterly/semi-annual/annual testing, then you should be fine.
NFPA 1 Fire Code requires that all smoke detectors be replaced when they fail the periodic sensitivity testing. Since many consumer products cannot be effectively field tested without damaging them, they must be replaced every ten years - same for CO detectors.
