After setting the alarm on a SCIF, which form must be completed?

The correct form to be completed after setting the alarm on a Sensitive Compartmented Information Facility (SCIF) is the SF-701, also known as the "Activity Security Checklist." This form is used to document actions taken to ensure that security measures are in place prior to the start of work in the SCIF, including the activation of alarm systems. By completing the SF-701, personnel confirm that they have followed the necessary procedures to safeguard classified information and that the environment is secure.

In the context of SCIF security protocols, the SF-702, which is the "Security Container Check Sheet," is used to document the opening and closing of containers that store classified material, and is not specifically related to alarms. The SF-703, known as the "Secure Address Form," and the SF-704, the "Security Violation Report," also serve different purposes and are not applicable to the immediate actions required after setting an alarm. Thus, the SF-701 is specifically designed for ensuring security readiness, making it the correct choice in this scenario.
