Which term describes alarms that are not caused by hazardous conditions and are considered Unwanted?

• A. Malicious Alarms
• B. Nuisance Alarms
• C. Unintentional Alarm
• D. Unknown Alarm

Answer: (D)

Alarms that occur without a hazardous condition and are considered unwanted are described as nuisance alarms. This term covers triggers from non-emergency factors—dust or moisture on sensors, insects, improper maintenance, or other sensor faults—that cause the system to activate even though there’s no real fire. Recognizing nuisance alarms helps responders focus on true emergencies rather than responding to false alerts. Malicious alarms imply intentional triggering, which is a different scenario. An unintentional alarm can be accidental, but the established label for unwanted, non-hazard-related activations is nuisance alarm. An unknown alarm suggests the cause isn’t identified, which isn’t the same as being unwanted and non-hazardous.
