Question: 1 / 400

What is a common reason for false alarms in a fire alarm system?

Interference from other electronic devices

Low battery power of detectors

Environmental conditions like smoke from cooking

A common reason for false alarms in a fire alarm system is environmental conditions, such as smoke from cooking. Cooking activities can produce wisps of smoke or steam that may be detected by smoke detectors, particularly ionization detectors, which can react to particles present in the air. This kind of environmental interference is one of the most frequent causes of false alarms in residential and commercial settings, especially if the detector is located too close to kitchens or cooking areas.

This scenario highlights the importance of proper placement of smoke detectors, as placing them in areas affected by normal day-to-day activities can lead to unnecessary alarms and may cause alarm fatigue among occupants, leading to potentially dangerous situations if a real fire occurs and people become desensitized to alarms.
