Question: 1 / 1030

The most common cause of false fire warnings in continuous loop fire detection systems is

Low battery

Dents, kinks, or crushed sensor sections

Dents, kinks, or crushed sensor sections are the most common cause of false fire warnings in continuous loop fire detection systems. This is because these damages to the sensor sections can interfere with the accurate detection of fire or smoke, leading to false alarms. The other options, low battery, high humidity, and electrical interference, may also cause false alarms in some cases, but they are not as common or frequent as physical damage to the sensor sections. It is important to regularly inspect and maintain the sensor sections to prevent false fire warnings.
