If smoke alarms are powered by a primary battery, all power requirements must be met for at least how long?

Smoke alarms powered by a primary battery must meet all power requirements for a minimum duration of one year. This duration is critical because it ensures that the smoke alarm remains operational during its expected life cycle. Smoke alarms are essential for early detection of fires, and a reliable power source is crucial for their functionality.

The one-year requirement is based on industry standards and safety guidelines that aim to provide assurance that the smoke alarm will function continuously and effectively within its intended operational timeframe. Regular testing and maintenance, including battery replacement at specified intervals, is necessary to ensure that the alarm will properly alert occupants in the event of smoke or fire.

Understanding these timelines is essential for compliance with safety regulations and ensuring the effectiveness of fire safety systems in residential and commercial properties.
