To prevent false alarms in a fire alarm system installed in a dusty environment, several specific measures should be implemented to minimize the impact of dust on the system's detectors and components. The first measure is to select appropriate detector types. Photoelectric smoke detectors are generally less susceptible to false alarms from dust than ionization detectors. Photoelectric detectors detect larger smoke particles, while ionization detectors are more sensitive to smaller particles, including dust. Heat detectors can also be used in areas where dust levels are very high, as they are not affected by airborne particles. The second measure is to use addressable smoke detectors with drift compensation.....
