What causes a malicious alarm?

• A. An individual when there is no fire event
• B. A faulty water valve
• C. A power outage
• D. A scheduled test

Answer: (A)

A malicious alarm is typically initiated by an individual who activates the fire alarm system without any actual fire event occurring. This action can result in unnecessary panic, potentially overwhelming emergency response systems, and can divert resources from real emergencies. The intent behind such an action is often to cause disruption and fear rather than to signal a legitimate hazard.

In contrast, the other options describe scenarios that do not reflect intentional wrongdoing. A faulty water valve may lead to issues with a sprinkler system but does not involve human intent. A power outage can disrupt alarm systems but is typically considered an operational failure rather than a malicious act. A scheduled test is a recognized practice meant to ensure systems are functioning correctly, again without any intent to deceive or cause alarm.
