A false positive is when a scientist determines something is true when it is actually false (also called a type I error). A false positive is a “false alarm.” A false negative is saying something is false when it is actually true (also called a type II error).
1) Human error. By far and away the most common cause of false alarms being triggered on home security systems is simple human error.

Unwanted fire signals from fire alarm and fire detection systems, where alarms operate due to a mechanical or electrical fault, or false activation by non-fire conditions (e.g. cooking fumes, dust, cigarette smoke).
User error, weather conditions, system malfunctions or improper installations and a wide range of other reasons resulted in approximately 95 percent of all alarms to be false in 2023. To reduce the number of Residential false alarm incidents, check the property for: Alarm system batteries (low or old)
False alarms, also known as “false trips,” occur when a security system mistakenly detects an event, activating a detection device such as a motion sensor or smoke detector due to accidental or harmless conditions.
A false alarm is any alarm activation caused by human error or equipment malfunction requiring a police response, with no evidence of an actual crime having been committed.
False alarms are commonly caused by human error, unintentional calls, system malfunctions, old or faulty equipment, malicious calls, lack of maintenance and more.
False Alarm is caused by the inability of brain to distinguish, in the early stage of cognitive processing, stimulus objects with similar appearances. When the brain is able to distinguish the differences between different stimulus objects in the late stage of cognitive processing, False Alarm disappears.
This type of alarm sets off an erroneous report of an emergency, causing undue panic and/or bringing resources, such as emergency services, to a place where they are not needed. False alarms have the potential to divert emergency responders away from legitimate emergencies, which could ultimately lead to loss of life.
Approximately 80% of false alarms are caused by simple user error. Other common causes include installation mistakes and improper system maintenance. The good news is that these false alarms are largely avoidable.
A false alarm or unwanted fire signal (UWFS), is defined as an alarm activation resulting from a cause other than a fire. If an AFD and Fire Alarm System is correctly maintained, it can significantly improve safety by detecting a fire and sounding the alarm at the early stages of a fire's development.
