What does code 910 signify?

• A. In Service
• B. Suspicious Person
• C. Suicide
• D. Prowler Outside

Answer: (D)

Code 910 is a specific exterior threat alert: a prowler outside. It tells responders there’s someone outside the property who may be attempting to gain entry, so units should prioritize perimeter awareness, secure entry points, and coordinate with responding officers to locate and handle the suspect while keeping bystanders safe. This is distinct from a general “in service” status, which just means an officer is available, or a generic “suspicious person,” which can refer to someone anywhere and doesn’t specify activity outside the structure. It’s also different from a call about a suicide, which involves a mental health crisis and requires a different kind of response. When 910 is announced, the focus is on exterior threat assessment, containment, and backup as needed.
