What is an important specification for smoke detectors in commercial buildings?

In commercial buildings, smoke detectors play a critical role in ensuring safety and compliance with fire codes. One important specification for smoke detectors is battery backup, which ensures that the smoke detectors will continue to function even during power outages. This is crucial for maintaining fire safety at all times.

Low power consumption is another important specification because it allows for extended battery life and reduces the frequency of battery replacements, ensuring that the smoke detectors remain operational with minimal maintenance.

Compatibility with other systems is vital as well, especially in larger commercial environments where smoke detectors need to interface with fire alarm systems, building management systems, or emergency notification systems. This integration allows for coordinated responses to fire events, improving overall safety.

Given these specifications, it can be concluded that all of these factors—battery backup, low power consumption, and compatibility with other systems—are essential in ensuring that smoke detectors operate effectively, making the option that encompasses all of these points the most comprehensive and correct choice.
