What is a requirement for the maintenance of smoke detectors in residential buildings according to codes?

For the maintenance of smoke detectors in residential buildings, testing them monthly is crucial. This requirement ensures that the smoke detectors are functioning properly and can effectively alert occupants in the event of a fire. Regular testing helps identify any issues, such as dead batteries or malfunctions, which could prevent the detectors from operating when needed.

While it is important to follow the manufacturer's recommendations—is often seen as best practice—it is commonly mandated in various property maintenance codes. This consistent approach to testing promotes safety and increases the likelihood of prompt action in emergencies, helping to protect lives.

Replacing smoke detectors every five years is a recommended practice, but it is not universal across all codes, making monthly testing a more universally applicable requirement. The other options, such as connection to hose pipes, do not pertain to smoke detectors under typical residential code requirements, and claiming no specific requirement undermines the emphasis on regular maintenance standards that prioritize safety.
