When your smoke detector's battery life is running out, a high-pitched 'chirp' usually signals the need to change the batteries. Yet, maintaining proper functionality of your smoke detectors involves an extra measure. It's crucial to remember that, besides just replacing the batteries, it's vital to swap out the smoke detectors once they reach a specific age. FEMA recommends replacing smoke detectors every 10 years from their production date. Contrary to the audible 'change battery' warnings, the signal to replace the entire smoke detector is silent.
