What is the required power source configuration for carbon monoxide alarms in a new building?

The required power source configuration for carbon monoxide alarms in a new building must ensure reliable operation in a variety of scenarios, especially during power outages. This is why the combination of commercial power and a battery backup is mandated. A reliable power source is crucial for safety equipment; hence, using both an AC power supply and a battery ensures that the alarm functions continuously, even if there is a failure in the electrical system.

The AC power provides a constant source of energy for day-to-day operation, while the battery backup ensures that the alarm remains operational during outages. Regulatory standards, such as those outlined in building codes and safety guidelines, emphasize this dual-source approach to maximize safety.

Using an alternative source such as battery only would not provide the continuous power necessary for optimal function, and while solar power provides a renewable option, it could be unreliable due to weather conditions, making the commercial power and battery combination the most effective choice for consistent monitoring of carbon monoxide levels.
