Which of the following factors can contribute to false alarms in fire detection systems?

The correct choice highlights critical factors that can lead to false alarms in fire detection systems. Environmental interferents refer to elements in the surroundings that may trigger the fire detection system inadvertently, such as steam, dust, or chemicals that resemble the signatures of smoke or heat. Improper installation can exacerbate these issues, as detectors might be placed in locations where they are more susceptible to false readings or not calibrated correctly, leading to erroneous alerts.

In addition to environmental interferents and installation issues, other factors, such as maintenance neglect, wiring problems, and human error, may also cause false alarms, but these are not limited to just those factors alone. The right choice captures a broader scope of influencing elements that can undermine the reliability of fire detection systems.
