Police Radio Codes – Emergency, Crime, Traffic and Support Practice Test

In police radio code usage, an alarm has its own specific numeric code within the 10-series. This coding lets dispatchers instantly recognize that an alarm has been triggered at a location and respond appropriately, without needing a lengthy description.

The alarm code is designated to convey that the situation involves an activated security system, signaling officers to treat it as an alarm event and prioritize the response. This helps ensure the right resources are sent quickly and that the call isn’t confused with other incident types like a welfare check, a disturbance, or a follow-up.

Other numbers in the same family map to different incident types, so they wouldn’t accurately represent an alarm. By using the alarm code, the system communicates the exact nature of the event, prompting the proper, timely response.
