When responding to an alarm, the appropriate action for a security guard is to investigate the cause of the alarm. This step is essential as it allows the guard to assess the situation before taking further action. By investigating, the guard can determine whether it is a false alarm, a mechanical error, or an actual security breach that requires intervention.

Investigating helps to prevent unnecessary panic or disruption and ensures that proper protocols are followed. In many cases, alarms may sound due to routine maintenance issues or errors, and by understanding the true nature of the alert, the security guard can efficiently manage the response.

While notifying law enforcement can be appropriate in some circumstances, especially if an actual threat is confirmed, initiating an investigation first allows the guard to gather information that could inform whether law enforcement needs to be involved. Conversely, silencing the alarm without investigation may lead to missing critical security issues, and ignoring alarms can result in missed threats and unsafe conditions. Thus, thorough investigation is a fundamental duty of a security professional in these scenarios.
