How often must conventional smoke detectors be cleaned according to FDNY guidelines?

Conventional smoke detectors must be cleaned semi-annually according to FDNY guidelines. This frequency is essential to ensure the detectors are functioning properly and free from dust, debris, and other contaminants that could interfere with their operation. Regular cleaning helps maintain sensitivity and ensures that the detectors can accurately sense smoke and alert occupants in case of a fire, thereby increasing safety in residential and commercial buildings. Cleaning them twice a year strikes a balance between effective maintenance and practicality, allowing for thorough inspections while minimizing disruption to the environment.
