Which code is used for SECURITY CHECK?

• A. 1026
• B. 1027
• C. 1029
• D. 1030

Answer: (B)

Understanding how radio codes compress actions helps you quickly interpret an officer’s transmission. A security check is a specific task where responders verify that a location is safe, often by sweeping the area, verifying doors and windows, and ensuring there are no hazards or unauthorized people present. This code signals to dispatch and other units that the primary objective is to confirm security, not to report a crime or request other services.

In this code set, the security check action is represented by the code 1027. That makes it the clear label for this task, so using this code immediately communicates the exact activity without extra words. The other numbers correspond to different duties or requests, so they wouldn’t accurately convey “security check.”
